I live in Florida and it is NOT cold here I am having the same darn problem. after its been running with the clutch down for a bit i pop it up putting it at full throttle then slowly rev it up if i don't maintain it JUST right it just dies on me. and if i rev it up to fast then let it go down it dies. I have a 92 tomos bullet TT with an A35 engine "basicaly the same as the targa LX" the chain is not on yet i just rebuilt this thing i cleaned the carb etc. it does have oil injection too.
