North-half ryder Posted April 10, 2009 Report Posted April 10, 2009 So I put a new wiseco crank in,(stock stroke) and an adjustable timing plate. Then put my old set of jugs and pistons back on.(65mm) started it up, and shee was running backwards. Got the timing set so I'm runnin the right way, then shee won't start!! Got good blue spark, carb slides in the right way, e-brake and tors plugs removed, clean carbs, new reeds, new plugs, stator pickup gap at a business card thickness. The motor would start but not rev when I had the slides in backwards, but when they were switched, no start. I'm runnin stock mikuni's, tors removed. I been at this all week, an I'm befuddled. Any help???? Quote

MILO Posted April 10, 2009 Report Posted April 10, 2009 crossover tube in place, carb bowls switched, floats need set, carbs in sync. that's where i'd start. if all is good, i'm sure someone here can help you dig a little deeper. Quote

Unfortunatly I all that too. I'm just blown away on why it won't run. Sure would like to figure it out!! Quote
brian Posted April 11, 2009 Report Posted April 11, 2009 Look for the obvious leaks at the intakes/reeds. Also do a leakdown test to make sure the base gaskets and seals are good. If all that checks out you need to take a closer look at the carbs. Cuz if you have good spark and no fire then you either arent getting any fuel, or you are getting way too much fuel. Quote

Thanx for the advise guyz, I'll let you know if/when I get her running. Quote

Well, back to the draw'n board!! Quote
