I am getting my sons 94 M944 monster (high comps, Keihin carbs, open airbox) running again. Sprage clutch went out. Have it all back together and bike turns over fine now. Problem is when its cold it turns over but wont start very easily. It also backfires as its turning over. I blew out all the passages I could find with compressed air in the carbs themselves. Didnt seem to change anything. I disassembled the timing plate getting to the sprage clutch. Upon assembly I noticed the light weight flywheel didnt have the timing marks like the stock flywheel. I kind of winged it when assembling the timing plate since I dont have the marks as a reference. I retarded the timing slightly, but was wondering if the timing was too much retarded if that would cause it to backfire when starting cold. When starting hot no problems at all. And the bike runs like a raped ape. I also backed out on the fuel mixture screws underneath the carbs about 1 turn from the recommended settings. When starting I twist the throttle 2 times then just crack the throttle to start. Any input would be appreciated as I am going to sell the bike and it needs to start easier.
thanks
