    How do u find valve clearance specs? I’ve got a taotao 110 I want to make sure the valve lash is set correct

    • @VermontLife
      @VermontLife  4 месяца назад

      Hard to find any specs on these. When you buy a head they come with the valves already in them. Best thought as this is a Honda clone would be to get a spec for a Honda version and work from there. Other option I’d consider would be to pose the question to some Tao Tao Facebook groups and see what you get for feedback. Sometimes there’s some really talented people in those groups just watch for the scammers.

    • @VermontLife
      @VermontLife  Год назад

      Are you sure you don’t have a bad crank bearing giving some extra resistance? Try turning over by hand and feeling through the compression resistance. You’re looking to see if there are any other resistance ‘spots’. Not sure if I think valves would do that unless your valves are stuck. Good luck.

      ​@@VermontLifeyeah me, my dad and my brother having a similar issue with our 125cc, we couldn't get spark from our spark plug so we had to replace the stator which finally gave us spark but now we encountered a new issue where the atv wouldn't start when we put the spark plug into the atv, but when we take it out of the atv, the engine moves, and causing a bit of smoke with the red wire from the battery? Any tips?

    • @VermontLife
      @VermontLife  5 месяцев назад

      Huh, the way you describe it… there is too much compression for the starter to turn the motor over when the plug is in. When you take the plug out you then have no compression and the starter can turn the motor over… sounds like a bad starter. Then you have the smoking red wire. Sounds like you are really overloading the circuit. Feels like you have resistance somewhere and/or bad starter.

    I have a prs 110cc kids atv, i recently had the starter burn up and melt the battery wires , i added new starter , new wiring harness and all new electrical components, and new battery
    The issue is when i go to start it the starter only turns the motor over about half way before hitting the compression stroke and then the starter want turn the engine any further but when i remove the spark plug it turns over free with the starter , so i out the spark plug back in and same issue to much compression for the starter so i just removed the far rocker cover and ban it turns over free when that is removed , installed the rocker cover back , and it does the same thing again , timing is correct im stumped on y the starter want get past the compression stroke of the engine , please help trying to get this atv going for my daughters

    • @VermontLife
      @VermontLife  Месяц назад +1

      Hmm, my first thought would have been weak starter as it turns fine without the plug in. If you take the little circular cover off on the stator side and put a socket on the nut to turn the motor over by hand does it still feel like a compression stroke or does it feel like it is binding up like a shot crankshaft bearing for example? It seems something is giving you resistance that the starter can overcome without compression but the added force needed to overcome compression plus ‘perhaps’ a crank bearing is too much. I have a video where I find that I have a bad crank from low oil/no oil and repair it if that helps but overall I had a very similar issue and it was my crank bearing. Good luck and let me know what you find.

      @@VermontLife well i noticed when i had the clutch cover removed and put the spark plug back in and the rocker cover back on and tried to start it as the starter gets to that compression stroke i can actually take my hand and it seems to spin pas that point very easy but anyway as i spin the clutch a little to get past that compression point and make the motor turn past the compression stroke allowing the starter to still but in motion but when it makes the full revolution it stops again every time at the compression stroke , so either the new starter is just cheap and weak or that bearing is bad like ur saying i cant think of anything else unless the valves are not accurately adjusted properly but idk if that would cause that

    Having trouble with my lads atv 110cc chinese quad at the moment, so its been laid up for around 6-8 months but with ethanol free fuel, it WAS starting absolutely fine, iv charged the battery full and also got a jump pack on it incase it gets low - i pulled the spark plug and ground it an turned it over, its sparking maybe not PERFECT but its sparking, there appears to be fuel getting through to the carb at least - would my next port of call be firing some starter fluid down the neck of the carb with the air filter removed to see if it fires?

    • @VermontLife
      @VermontLife  Год назад

      A little starter fluid into the air filter should be enough. Sounds like you have fuel and spark. Unless you’ve sheared the timing key (unlikely as it had only been sitting and was running when you parked it) you have mechanical timing as well. Perhaps your compression is low but overall I’d hit it with a little starting fluid, get it warmed up and running and see how it does after that. Good luck.

      Electrical timing, sounds like you checked the mechanical timing by inspecting the timing gear and chain etc. a bad stator, bad stator wiring or bad CDI could cause that. I had to diagnose that on the yfm350er videos I did. In the end it was a bad cdi for me.

      No, should be on the intake stroke. Make sure the intake and exhaust valves are opening and closing properly. Might just need to have the valves adjusted at that point. If they are way out of spec it will have low compression and not start.

    Would you have any idea what would be the problem with my atv ? It’s just like the one in the video. So after a day of riding it suddenly stopped and wouldn’t crank anymore. My guess was that it overheated so I let it cool down but ever since that it hasn’t started again. Where do you think I can start by looking ?

    • @VermontLife
      @VermontLife  3 года назад

      Does the motor crank by hand? IE pull the plastic cover off the stator bolt hole by the left foot well and put a socket wrench in there to see if the motor is seized. If it is seized then there's a motor issue to go after. (no oil burned it up, part broke internally etc.) If you can turn it by hand then I'd check the basics. (Did your battery short out and is dead? Did a ground wire come loose. Do you get a click when you press the start button to make you believe you should check the solenoid etc.) I'd start with the above.

      @@JoseDiaz-zv3wp It would be the timing chain. It's not too bad a project. You should be able to remove it and replace it without taking the motor or head off. You'll access it by taking the stator cover off and a side cover on the head. Look for videos on timing chain replacement for tao taos and watch a video on two on finding top dead center on an atv like yours. With luck only the chain snapped and there's no or little other damage.

      Sounds like carb issues. Does it start and idle? What happens as you slowly give it throttle? (Ie spit and sputter, backfire, just bog out and die.) How it responds will help determine what the issue is and if the carb is the issue at all. option two… the clutch is worn out and not engaging until high rpm.

      No, a woodruff key is a half moon shaped ‘key’ that’s sits in a channel in the crankshaft. It ensures that when the flywheel spins the crankshaft does as well. You would need to pull the flywheel to check which implies you would need a flywheel pulled tool.

      Have you confirmed you have spark? I would pull the plug out, keep it attached to the coil and ground it to the chassis. You should be able to kick it and see blue spark. It might be helpful to have someone else kick it over while you watch. If you have spark then put a little starter fluid down the spark plug hole and try to start it again, if it starts then dies you likely have a fuel issue. If that’s the case you may need a carb cleaning. There could be a number of things but confirming spark is a good first step.
