Emhyr Posted March 27, 2013 Report Share Posted March 27, 2013 Hi all on start i'm sorry for my english ;-) I have some problem with my shee, it started to run only on right side piston (left pipe is cold after ride) i dissasembled whole intake (airbox carbs reeds) , iv'e looked on pistons thru the intake ports and they look good any scratches/rings look good too - it's not an electrical issue (good blue spark) but something don't let me sleep - left piston got alot of free play (not forward-> backard) but left right 0_0 i can turn pisotn from intake side about 2-3 mm left and right - i know it's not good but could it avoid firing on that cylinder? compression i strong in my opinion but have much difference between cyls (left not firing 150psi, right running good has 170psi) ps it isn't a carb issue to because i run 2into1 Thanks for all ideas, i dont know what to do now - tearing it down (head.jugs) or look to find some other issue Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted March 29, 2013 Report Share Posted March 29, 2013 I would pull that cylinder and look at it better. Either the pin bearing is shot or the big end (crank) bearing is shot. Quote Link to comment Share on other sites More sharing options...
blowit Posted April 3, 2013 Report Share Posted April 3, 2013 No, radial movement of the LH piston should not cause what you are describing. I would recommend swapping the plug cab L ro R to be sure but if you are confident this is not electrical, that pretty much leaves carbs. When you sense the L side pulling back, pull the choke and see if it comes back. If it does, you know you need more fuel on the L. Check carb balance (slides), and carb clean. Usually the pilot jet is plugged. Brandon Mull Engineering Quote Link to comment Share on other sites More sharing options...
