I am putting the head back on my 110cc motor I took the timing chain sprocket off the camshaft when i dismantled it. I have know idea how to set up the timing and the site in the how to section does not really - im having trouble understanding it
get the motor at TDC, piston at the top, with the timing mark on the flywheel pointing straight up to 12 o'clock,
then the cam gear has a pointer at one tooth, this points to 9 o'clock
Firstly take the ignition cover off the engine. Turn the flywheel around until the letter T lines up with the small groove above the flywheel. This is T.D.C on your crankshaft . Then with your top valve cover off with a light check that the 2 cam lobes are facing towards the piston. In this position you should be able to line up the cam sprocket holes up with the cam holes and there is a small circle or arrow on the cam sprocket that should line up with a V groove at the 9 o'clock position on the head. Before fitting the sprocket to the cam,fit the timing chain to the cam sprocket then to the camshaft and then fit the bolts and tighten. Just make shore that you keep the T on the bottom of your engine lined up when you install the cam sprocket and chain to the camshaft. It would be good to check the valve clearances at this time there is a tutoral on this site on how to do this. I hope this helps you. I have done this many times but this is the first time i have had to explain it so i hope it is clear if anyone else would like to add to this they are welcome.

Don't these things have marks on the sprockets?
Can not find a mark on the crank shaft sprocket
This is the timing marks on the camshaft sprocket, note how the three bolts are sitting, that way you cant have the timing out 180 degrees.
This is the timing marks for the flywheel, as long as the flywheel and the camshaft sprocket marks are aligned with the chain on then your timing is set
flywheel markings
camshaft gear markings
Hey i was trying to set it with the magneto off and did not see the marks Thanks for the photos.
Because i took the cam sprocket off i am still confused with what you are saying
I have the crankshaft lined up on the t and the camshaft is between lobes is that right
the camshaft lobes are to face towards the piston

See the cam sprocket picture, that explains how it should sit while the magneto is on the T
Thanks for yor response to this amateur Where is thetiming chain adjuster as i am having a real problem putting the cam sprocket and chain on
At the bottom of your engine on the ignition side it will be on a angle.
there is a bolt on the bottom/underneath of the motor, just back from the crank line
undo it and it will spring out, then there is no tension left on the chain
Thanks for your response, i could not find a mark on the camshaft housing but tried to set it up on your info and it came up good.
The bike is running awsome
aah i get you, just done it and the engine fired up great, thanks for the help, those pics are really usefull.

Chinese-made ATVs like the TaoTao 110cc ATV have been growing in popularity in the past decade for a good number of reasons. They are affordable and good beginner vehicles for kiddos and youngsters training for more serious riding. This article will go over another one of these economical off-road wheelers.
The TaoTao 110 ATV is a U.
S.-manufactured Chinese kid quad by Tao Motor. It features an automatic transmission, a speed limiter, a wireless key fob with an engine shut-off, utility racks, and a California Green Sticker. This mini machine perfectly caters to both beginner and experienced youngsters.
The quad’s rugged steel frame, full suspension, and a wide array of color options make it a massive hit with parents and kids who want to bond over experiencing the outdoors. Plus, it makes it a very viable choice for a fun, safe ride. Does the Chinese ATV truly live up to its reputation? Read on to find out.
Despite what others may think, TaoTao 110cc ATVs did not inch their way into the off-roading landscape simply because of their low price point. Like any other Chinese-made quads, TaoTao wheelers are feature-rich machines with all the safety features kids would need as they embark on a journey to off-roading and drag racing. Big-name brands provide quality, durability, and a solid platform for practice – and the TaoTao ATV does so, too.
Introduced to the public in the past half-decade, the TaoTao 110cc ATV had a total of five models and approximately 11 trims released in the market, as follows:
All these models boasted an automatic transmission with reverse, full suspension, a multitude of color options, and tons of safety features parents would love. They had bike-like handlebars that provide the young rider good control of the quad. The rear rack offered an 11-lb (5 Kg) carrying capacity – great for snacks and some protective gear. Full floorboards allowed for sure footing while riding on bumpy or wooded trails.
The Tao Tao 110 ATV is brought to life by a four-stroke, air-cooled, single-cylinder engine. Engine displacement is 107 cm3, and the bore-stroke ratio is 52.
4 x 49.5 mm (2.06 x 1.95 inches) with a compression ratio of 9.5:1. The air-fuel mixture is handled by a 19-mm PZ19 carburetor and 35-mm fully adjustable air filter. Fuel tank capacity is 2.3 Liters/0.60 US gallons.
Recommended fuel is unleaded gasoline with a PON rating of 87+ or RON rating of 91+, while oil would be 15W-40 standard motor oil, like Valvoline VV70506-05 Premium Blue 15W40 Motor Oil (view on Amazon).
Power travels to the wheels via an automatic transmission with neutral and reverse and a centrifugal clutch assembly. Its foot-operated chain drive has a maximum torque of 6.5 ft-lb (8.8 Nm @ 6,000 RPM) and marketed top speed of 33 mph. It comes with an adjustable speed limiter that slows down the machine by turning the adjustment screw clockwise and increases the top speed by doing the reverse.
The TaoTao 110 is powered by an electronic CDI ignition with an auxiliary pull-start system. An AC-Magneto alternator powers up electronic accessories.
The wheeler requires a 12V 4Ah 70-CCA (Cold Cranking Amps) 5L-BS battery with assembled dimensions of 4.49 x 4.21 x 2.76 inches (114 x 107 x 70 mm – L x W x H) – excluding wiring harness and mounting accessories. It requires an NST A7RTC or an NGK CR6HSA spark plug with a 0.024- to 0.028-inch (0.06-0.085 mm) gap.
Tubeless valved 14.5 x 7-6 front and rear tires with textured tread are mounted on steel rims and enable this youth ATV to navigate diverse terrain, making it beginner-friendly. Tire pressure should be 34.47 kPa (0.35 kg/cm², 5 psi). 68.95 kPa (0.70 kg/cm², 10 psi) should be the maximum pressure when seating the tire beads. When airing down your knobbies, never go below 13.79 kPa (0.14 kg/cm², 2 psi). Replace stock rubber with Kenda Scorpion K290 ATV Tires (view on Amazon) in case of wear and tear.
This four-wheeler is equipped with hand-operated front mechanical drum brakes and foot-operated rear hydraulic disc brakes – unlike the brake setup for most ATVs with hydraulic disc brakes found at the front and mechanically sealed drums placed at the back.
The TaoTao 110cc ATV features 10.8-inch front shock absorbers and 9.6-inch rear shocks without rebound damping. You may find stock front suspension to be too long for the vehicle (and too stiff for young riders despite being on the softest setting). In this case, replace them with shorter shocks for the quad to operate correctly and prevent the shock from slamming or jumping back to its stock position.
While there is nothing documented in the service manual, you can determine the optimal shock length you need with a bit of testing. Do this by placing the front end of your wheeler on a jack stand and removing one of the shocks (keep the wheel in place).
Next, see if bump steer exists by cycling the wheel up and down through the range (this is the paramount issue that needs addressing). If it does, select shocks that allow the wheel to travel up and down without turning left or right spontaneously.
The quad’s overall dimensions are 45.
7 × 28 × 33.3 inches (1,160 x 711 x 845 mm – L x W x H). Conversely, carton dimensions are 45.5 x 27.2 x 24 inches (1,155 x 690 x 610 mm – L x W x H). The vehicle wheelbase is 31.5 inches (800 mm), while its seat height is 24.4 inches (620 mm). Gross weight is between 205 and 225 lbs (93-102 Kg), depending on the ATV model. The maximum loading capacity is 132 lbs (60 Kg).
The TaoTao 110cc comprises a tubular steel frame and plastic body material (in Pink Camo, Yellow Camo, Green Camo, Black, Burgundy Red, blue, Red Spider, Black Spider, Pink Spider, and Blue Spider). All models feature modern aesthetics and an 11-lb-capacity rear utility rack.
The fuel tank is under the driver’s seat. The front brake and throttle levers, speed limiter, parking brake button, and lanyard are on the right handlebar, while the main and start/stop switches are on the left.
The list price of a TaoTao 110 ATV ranges from $799 to $1,099, depending on the seller, trim, and whether the quad is delivered fully assembled.
This amount generally does not include shipping fees, liftgate service, and product warranty – although other reseller sites like TX Powersports already include shipping expenses in the four-wheeler’s resale price.
Buyers can even get more savings by purchasing more than one unit. Layaway and finance plans are also available for consumers who cannot pay the full cost of the wheeler upfront.
Based on most (if not all) Chinese ATV forums, the main complaint about the Tao Tao 110 ATV has to do with no spark, starting, or idling issues. And TaoTao owners could not agree more. Like full-sized ATVs, starting problems with kiddie quads typically indicate plugged fuel lines or a dirty carburetor.
It is not necessarily a standard problem for Chinese wheelers. But for buyers of secondhand units, this is something to be expected, especially if the vehicle has had multiple previous owners.
Since the TaoTao ATV has a fully automatic transmission, you can skip checking on the choke position.
However, compression and voltage tests, spark plug inspection, and CDI box/wiring diagram checks are still required.
Part of what you need to inspect should be ensuring that exciter coils are producing a lot more volts and black/white kill wires are earthed with the correct switches. Rule out a potentially defective trigger coil or CDI box by swapping either one out with a working unit.
In some cases, the stator cover may need to be removed to see if there is a wire cut in half. Repairing this usually gets your quad’s spark back and takes care of starting issues. Other times, a simple gasket replacement or fuel change does the trick.
Owners often forget that the TaoTao 110cc ATV is a bit picky with fuel and ethanol-added variants (with sulfuric content) lead to a clogged carb and an adverse reaction with TaoTao 110cc ATV parts having brass and aluminum components. A fuel stabilizer helps mitigate damaging effects. But the right type of fuel always works best.
Installing a battery-off switch in the wheeler will prevent battery drain when the vehicle is not in use.The TaoTao 110cc ATV top speed is 33 mph (53.1 km/h) and could be lowered further, depending on how young the rider is. This speed perfectly fits youngsters and first-timers. But for those who find the quad’s top-end lacking, here are some things to try to help increase it:
Many experienced owners advise upgrading to a higher fuel rating in moderation so as not to blow up the engine right away.
Going one to two fuel-grade points each time is fine – for example, going from 85 to 87 instead of jumping straight into a PON rating of 91. Additionally, researching the fuel composition is also recommended, as some higher-grade variants may have additives that are harmful to your ATV.
These components comprise a more unorthodox approach but are guaranteed to increase your TaoTao 110’s top speed. The fan makes for forced induction, while the alcohol injection for more combustion. When put together, more airflow and combustion mean more power.
Porting the head, having a good cold air intake, and taking the exhaust system out are also sure-fire ways to wake up your quad’s powerplant. The biggest challenge with these is that you may not find many aftermarket parts to accomplish this job since 110cc ATVs were designed initially for kids or younger riders.
Taking off useless or unnecessary parts from your 4×4 reduces aerodynamic drag and helps improve top speed.
Not so much so on a straightaway, but this will be evident when going uphill. Pair that with new shocks for better bump absorption, and you are certain to go faster off-road. Complete the setup with new tires and wheels (these also improve your vehicle’s handling characteristics), new clutching, a larger carburetor, and different gearing – and you are all set.
Tao Motor – the maker of TaoTao 110cc ATV – is a subsidiary of Taotao Vehicles Company Ltd. It is a premier Chinese motorsports vehicle manufacturer that produces all-terrain vehicles, dirt bikes, go-karts, scooters, and electric vehicles.
This firm has earned itself a reputation for producing quality ATVs at family-affordable prices and has several warehouses in Indiana, Georgia, California, and Canada. Tao Motor has followed through with its commitment – to provide families a means to revel in the outdoors on value motorsports vehicles. Today, Tao Motor continues to develop and expand its product line and services.
TaoTao 110cc ATV reviews are largely positive, and that is what is great about this vehicle. Given its price point, it surprisingly delivers on quality, features, and capabilities. It has a sleek, sporty design, is beginner-friendly yet versatile, and is one of the few youth ATVs that can boast of a California Green Sticker. It rides great on trails, tracks, and dunes.
Installation and repair are not as difficult as counterparts – thanks to its huge community and aftermarket support. It is an off-road vehicle youngsters can learn from without hurting their wallets so much.
So, the question remains – does this Chinese ATV live up to its reputation? I would say yes – it does!
In order for the ATV to work like a clock, the rider needs to regularly carry out a complete maintenance of the equipment.
And a key element of maintenance is ATV carburetor adjustment. Over time, the system starts to work incorrectly, which increases fuel consumption, worsens dynamics and other problems appear. So how do you adjust an ATV carburetor?
The operation and life of the engine directly depends on the quality of the fuel mixture. The carburetor is responsible for the preparation of the composition, but after prolonged use of the equipment, the settings “go astray”. This results in:
Many riders who decide to buy an inexpensive ATV simply do not spare the technique and ignore this procedure. But even if you plan to change your device in 1.5-2 years, adjustment is needed. The reason for this is increased fuel consumption. A quad with an untuned carburetor "eats" 30-40% more gasoline, and these are tangible costs.
So how do you adjust the carburetor on a Chinese ATV? For this you need:
However, it is important to remember that all adjustments are made only with a "clean" carburettor. This means that the rider needs to remove all the dirt from the node and flush the system to remove condensation and sediment from it.
Note: Just before adjusting, the engine must be warmed up to operating temperature.
To set the carburetor idle speed, the float chamber must first be cleared of fuel. To do this, start the ATV, close the fuel cock and wait until the machine stalls (5-10 minutes). To speed up the process, you can take a little ride on the quadric. Of course, gasoline can be drained, but in any case you will have to warm up the device, so the first method of "removing" gasoline is more effective.
Then:
Read the manual before adjusting the carburetor on a 125cc ATV to be sure. Remember that the location of the bolts is different in different devices, so read the documentation in advance.
To evaluate the quality of the fuel composition, make a test run.
After that, unscrew the candle, and evaluate its condition. If it is:
Also look out for these “symptoms”: damaged tip (electrode failure), oil deposits (damage to rings and caps), chips and inclusions (sign of motor failure).
To adjust the mixture you need to twist the needle cover and pull it out. To get the needle, pull out the cable. After that, move the ring in the required direction (lower - more air, but less fuel and vice versa).
Then start the engine and make sure it doesn't stall.
The last step in adjusting the 125cc ATV carburetor is adjusting the petrol level. To do this, you need:
Note: Adjust as carefully as possible as system components are very fragile. Ideally, carburetor tuning should be done by a specialist.

It often seems like an insurmountable task for beginners to tune and adjust the carburetor of an ATV, but in fact, it is far from being the case. Using our instructions, you can easily set up a carburetor with your own hands.
Due to improper carburetor settings, problems such as: failures during acceleration, jerks while driving, uncertain start of the engine, poor acceleration dynamics, overheating, loss of power, increased fuel consumption, formation of deposits in the combustion chamber.
So what exactly are we going to tune?
Attention! The adjustment is carried out under the condition of a warm engine and a clean carburetor.
First, make sure there is no condensation in the carburetor. First, you need to drain the gasoline from the float chamber, for this you need to close the fuel cock and partially unscrew the screw No. 1, after the gasoline has drained from the float chamber, tighten the screw No. 1.
Let's look at photos of candles with various deposits and defects.
A 100% indicator of a correctly adjusted combustible mixture is carbon deposits on a candle.
Consider the location of the screws for adjusting the quality of the mixture and idle speed of carburetors of different models.
#1 Float chamber plug; No. 2 Mixture quality screw;
#3 Idle adjustment screw.
1 - quality adjustment screw at idle; 2 - fuel inlet fitting; 3 - fitting through which you can sleep fuel from the float chamber; 4 - screw-plug of the float chamber.
1 - ventilation tube; 2 - idle speed adjustment screw; 3 - screw for adjusting the composition of the air-fuel mixture.
ATV carburetor speed and mixture adjustment.
1. Start and warm up the engine until it reaches operating temperature.
2. Adjust the idle screw to set the idle speed to normal. Completely, until it stops, tighten the fuel mixture screw, the engine should stall. If this does not happen, check the tightness of the air supply system from the air filter.
3. Loosen the fuel mixture screw 1 turn. (Turning the screw clockwise, we enrich the mixture, unscrewing it counterclockwise, we lean).
4. Start the engine and, by adjusting the idle screw, set the speed slightly higher than usual
5. Slowly unscrew the fuel mixture screw until the engine reaches maximum speed (we unscrew the screw no more than 2 turns, but depending range may fluctuate due to engine wear and other faults).
6. Re-adjust the idle screw to set the idle speed to normal.
7. Press the throttle trigger several times, check if the idle speed is stable.
Mixture quality adjustment with a needle.
Probably you have heard more than once about adjusting the quality of the mixture on the carburetor by manipulating the needle. I note that these are extreme measures, for the initial adjustment, use the mixture quality screw, and only if you do not get the desired result, unscrew the mount and remove the needle. What does she represent? This is the main element that regulates the amount of gasoline supplied to the combustion chamber. Connected directly to the throttle handle through a cable. When you turn the knob, the needle rises higher, opening up a channel for fuel, thereby delivering more mixture, which increases power, which translates into speed.
You will see 5 grooves on the needle at the attachment point. Initially, the retaining ring fixes it in the central position, this is the best option. But sometimes it is not possible to achieve the required quality of the mixture.
