Your piston is hitting your valves... probaly going to have to replace valves, or at least get your valves adjusted, but they might be bent now since the piston was hitting it... if thats what it is.

take the rocker cover/cam cover off .. an make shure that the rockers and sub rockers are moving freely .. and go from there ... they can stick really quickly from loss of oil

I dont know much about the best brand to get, they all gotta be somewhat good if they still make their product, so the brand isnt a big deal. I would go just look for your best price. I did the valve job on mine and it was like 18$ for one an 26$ for the other and they worked fine when it was running

Ya it ran great for the time that i was able to run it... my starter clutch went out a little while after that so it isnt running right now. But when i replaced the valves, i had my timing chain off by 1 chain link and my piston was hitting my valves again, and i was worried about my valves bending but i got that fixed again at work this time and the valves werent bent at all and it ran great after that too.

Are you able to do at least a valve adjustment by yourself? Because that might be all that is wrong with it and that way you will save a little money

      Hi guys I'm new to the forums and I need some help to make a decision. I recently started riding quads a few months ago and have been riding a Yamaha blaster. I'm now deciding of getting a raptor 350, Honda 400ex, trx450, or yfz 450. At first I looked into the 350 but I wanted more power. Recently I looked into the yfz and read it has a smoother ride and something about adjusting the cylinders? Any information on what I should get, pros? Cons? Would all be extremely helpful.

      Hi everyone,
      I have a question, if the starter clutch gear looks fine but is still not working correctly then all I should need to replace is the one way bearing, right?
      thanks,

      Just picked this up over the weekend;
      2001 400ex starts and runs great with fairly new rubber, nerf bars, aftermarket subframe (needs a grab bar), aftermarket bearing carrier & LEX MXe exhaust. Needs bushings and bearings front and rear. Oh yeah and it's got alum wheels too.
      It may be leaking at the bottom of the cylinder on the carb side (cleaned it all off and ran it/road it for an hour or so but didnt see any sign of oil or leaking and needs the chain replaced. picked it up for $1200
      If I take the cylinder off to replace the gaskets, should i do anything else while Im in there?

      I have a 07 trx 400ex. I had issues with the shifting. It would shift up to 2nd then hit a roof and go no higher. I took it apart and split the case. The shift drum works fine when shifting by hand or with pliers. But when you use the gearshift plate and shifter it will not move. Any ideas?

      i have an 06 400ex, just put on an hmf slip on exhaust, uni air filter with the airbox lid on, new spark plug, 42 pilot jet, and i started with a 160 main and when i checked the plug it looked a little dark so i switched to a 155 main. both jets ran perfectly fine. should i adjust the a/f screw and see what happens?
