01 cbr f4i help
Ok guys I hate to be that guy that post the same forum but
I've read a bunch and I'm still having trouble
Problem:
I bought a 01 f4i to stunt it's my first bike with a full set up
The guy I bought it from said it need new injectors and fuel and engine
Cut relays I bought all that replaced it bike cranks no fuel prime (with relays)
But when I jump them fuel pump primes bike cranks but won't start
I bypassed bas sensor checked fuses checked kill switch all good
I was checking connectors and I found one under the fuel tank three wires pink green and black I think can't remember now but it lead straight down to a connector going in to the engine idk what that is could that cause it to not start?
Would love some input from someone more experienced so I can finally ride
Thanks guys!

Re: 01 cbr f4i help
Its more than likley your tip over senor. Just search for f4i ttip over sensor bypass. I have no mechanical experience or know how and I was able to do it. It is in the upper fairing right by the headlight. The kill switches on f4i's are know to go bad as well. but my best guess is the tip over sensor. I have an 01 f4i that had the same problem- bugged the **** out of me for weeks and I did the mod and it worked just fine.
