SuperChris Posted February 27, 2005 Report Share Posted February 27, 2005 I had the same problem untill I built a pressure tester. Found that the whole motor was a leak. Fixed it and now the bike is totally different. Quote Link to comment Share on other sites More sharing options...

banshee boy 98 Posted February 27, 2005 Report Share Posted February 27, 2005 post a pic of the piston, so we can see it? did you do a leak down test? what is the compression on the motor? what fuel are you running? Quote Link to comment Share on other sites More sharing options...

FUTURE Posted February 28, 2005 Author Report Share Posted February 28, 2005 Not yet done leak testing ( tools no available in here ) I believe jetting is fine Today I will post pic of damage piston.

jeffro189 Posted February 28, 2005 Report Share Posted February 28, 2005 it is running lean ,lean, lean on the left side. look for an air leak ( can use starting fluid and spray aroud, and idle will change) or jetting in carb, or jet is somewhat restricted in the carb. few things too look for Quote Link to comment Share on other sites More sharing options...
Fireman-hott Posted February 28, 2005 Report Share Posted February 28, 2005 http://www.mztech.fsnet.co.uk/workshop/wrk_piston.html Match your piston to the picture and theres your problem. This link should be a sticky anymore. Quote Link to comment Share on other sites More sharing options...
Holyman Posted February 28, 2005 Report Share Posted February 28, 2005 Your crank could also be twisted allowing only the one side to be advanced too much. Quote Link to comment Share on other sites More sharing options...
