Hey bud, I'm working on a friends F4i right now. It's running strong at idle and has plenty of smoothe power while on the gas but......as soon as you roll off or pull in the clutch it dies. After it dies it takes a while to get it restarted again. 1 Known problem: It's been sitting for several months, but I put some STP fuel injector cleaner in and topped off the tank with fresh premium Does this sound like a tip over switch problem? Some other electrical issue? Any help would be appriciated.
