collyolly Posted July 7, 2021 Report Share Posted July 7, 2021 Hello again Blockage in the carb means that one of the small airways could be obstructed, if it was, the pilot system would not be working correctly so the bike starts on choke but then will not run when the choke is turned off. Try the compression test again after you have put a few cc’s of oil down the plug hole, this may seal up the piston clearance and give a higher compression result. If it does then you should investigate for ring and piston wear although I note you have replaced the piston and cylinder ! Good luck Quote Link to comment Share on other sites More sharing options...
KevinKOG Posted May 25, 2022 Report Share Posted May 25, 2022 75 psi is too low. It will not run. I see the post is almost a year old so probably you have solved it. Was it stuck rings? Quote Link to comment Share on other sites More sharing options...
