removed filler cap, still no good. If I remove fuel pipe from bottom of tank, fuel flows plenty.
The float chamber is not so accessible. Take about 10+ mins to get at it. So, the carb is the only thing I can't really check so well.
I've removed, sprayed carb cleaner all through it, and cleaned/dried with compressed air.
I do think it's fuel related though (just my thoughts)
The bike is also so powerless when moving off from stand still. If that is a hint to anything else? Unless all 50's are sluggish to get going from 0mph?
