hello i am the proud owner of a 124cc kit that i pit on a 2001 xr50 frame.... bike has run immaculate for years. i have a spark issue almost none to very intermintent. is there coil or stator problems? or cdi or harness issues u have run into before?! and where can i find a wiring diagram? i have found little to no information on troublshootig these motors. can u help?! when the bike kicks over it will run each time it will start for the same 2-3minute period then cut out. then not start again with no spark.... thanx
