My first post here and I’m looking for some help. I have a 2006 trx400ex that had an upgraded piston which caused the breakage of several parts. I have replaced the bottom end, piston, valves, CAM shaft sprocket, and a few other items. I have also had to redo the timing which is my first question. I have turned the timing both clockwise and counterclockwise does turning it the wrong way mess it up? my other issue is that it won’t start it had compression spark and gas but won’t start. the engine sounds fine (no knocking or anything like that) but every other second there’s like a puff noise that comes from the quad. hopefully someone will know what’s the matter and anything yall can help with would be great.
Thanks Ryan C.
