Left cylinder cutting out


Recommended Posts

New to this so hopefully I explain it right. first off mods cool head not sure what size domes, bored to 64.75, Toomey t-5 pipes and silencers, trinity stage 4 1 into 2 intake, keihin 35mm crab.bought the shee with all this on it blew up the clutch first month of having it. Did rebuild with moose gasket kit new clutch is a driveline HD it has hinson clutch basket in it also new piston rings and honed cylinders since rings had little wear. Rebuilt the engine did break in ran good first 3 rides and now it idles nice fires right up 1 to 4 kicks but about mid throttle left cylinder cuts out and give it more throttle seems to run lil bit and cut out back and fourth but mainly not as far as I can tell.got any ideas???checked compression its between 130 and 135 both cylinders.. switched spark plug wires to the other cylinder still left side, played with the caps resistor sounded lose so replaced them both with new NGK resistor caps still same problem got a coil from a friend haven't tried it yet not sure if it is even a good one..the reeds I'm not sure if stock or upgraded I haven't looked to see if they could be bad yet..wondering if any body has any other ideas on this problem, most people have two carbs and have my same problem but its usually there one side carb is bad.by the way I think my shee is rich when it before an after the build it lil boggy/rich sounding/feeling when taking off but more rpm better the power. Think it could be way rich were its fowling out my left plug? Some help would be very appreciated thanks..

oh yeah I live in salt lake Utah elevation is 4,226 ft and the dunes are 5,000 to 5,500 ft above sea level but I kinda ride every where..

Hopefully this make sense thanks

First task: punctuation and sentence structuring. 

 

Second task: Leak test

:whistling:  was going to warn about the grammer Nazis but my head hurt from trying to read it.

Thought about being the Nazi, but was tired.

 

Tried reading it again :whoa: Have you tried new plugs? Even if the yare new, swap plugs one cyl to other, might be bad plug. Clean nubs on flywheel and set gap with feeler gage. Check at both nubs.
