ok we this is it i have a 900rr and play w/ carbs but iam helpin my buddy w/ a 76 fx 9or something0 750 triple, cleaned the carbs aout and started great, but when it runs is slowly idles down and stalls and hates to start again w/ out playin w/ the trottle. the plugs are black and it WAS RUNNING RICH but seems ok now no fuel on plugs after about a solid minute of cranking the only thing iam leanin torwards is tank vapor locking, iam gunna check it after work seein if anyone could throw any thoughts for me.

 

ok i figured it out thanks everone

 

if it's a 750 triple, be careful when you take it for a test spin. seriously, a 750 two stroke, i'm jealous.
