  1. Sorry for not posting in over a month. Today is the first day in over a month I am able to work on the quad. If the piston and rings look good, what do you think the problem could be? I have a replacement piston, however I could not manage to get the long studs off.
  2. I am in a bit of a predicament right now. I managed to get the timing chain, camshaft, and head off of the engine but due to the engine still being on the quad and an odd frame design I am unable to fully remove it from the rest of the machine. I have managed to slide it and the cylinder far up enough to where I have clear access to the piston. I firmly believe that if I were to remove the engine from the quad that it would never run again. What should my next step be? Here are some photos of the piston and what I’m trying to describe:
  3. I can’t seem to get the chain off despite fully removing the chain tensioner. The chain has slack but not enough to remove it fully.
  4. I have removed the carburetor, exhaust, valve cover, and timing chain tensioner. I can’t seem to figure out how to remove the timing chain sprocket. Here is a photo of the sprocket:
  5. This is where I am at right now. How would I go about removing the valve system? I do not have a torque wrench (which I heard might be an issue).
  6. Sorry for not posting for a while. I got very busy the past two weeks. Anyways, I believe the problem to be oil getting past the piston rings and into the combustion chamber. The quad starts very hard and doesn’t stay running for long. I got a piston and ring kit to install. I’ve read online and am going to remove the exhaust and valve cover. How do I remove the valves so I can reach the combustion chamber?
  7. No more smoke and it drives just fine. Just gushing oil from the tube.
  8. I went on a longer ride (~10 mins) and everything is not ok. The left rear tire (the side the hose is on) is covered in oil spatters and the frame under the hose is too. It appears that I drained enough oil to the fill line but it didn’t work. On the bright side I’m no longer blowing smoke and the quad performs like it did before all of this.
  9. I tried what you suggested and it runs just fine! Just curious, why would it start smoking just now after about 30 mins of time spent riding it?
  10. Yes. Would that cause it to smoke from the oil vent hose?
  11. When I tried to start it up it started spewing white smoke. Not from the exhaust but just from the head of the engine. I shut off the quad as not to damage the motor any more. Any ideas what it could be? The white smoke started instantly after I started it, which leads me to believe that it isn’t oil that might’ve accumulated on the outside of the engine burning.
  12. Oil is coming from the end of the tube visible in the first photo. The tube is pointing directly down and is right over the oil spot visible on the ground. And as for the bolt missing I removed the bolts holding the footrests onto the frame so I could look under the engine easier. I was in the process of reattaching when I took the picture.
  13. A new issue has arisen that isn’t the brakes. I am leaking oil. There is a hose coming from the cylinder head that is leaking oil. Any help would be greatly appreciated. I have attached photos of the tube leaking oil.
  14. As the quad cost me $75 when I picked it up I don’t see the benefit in spending more than that for just the brakes. Now that I have a battery and don’t have to jump the quad there is no problem for me to hold the front brake lever in when stopped or just shutting the quad off.
  15. I have ridden the quad two more times since the first start and would now like to fix the rear brakes. In one of my first posts in this thread I falsely called the broken brake cylinder a clutch cylinder. In the image you see a brake cylinder with the bubble where the liquid should go shattered. How can I get the rear brakes fully operational?
