1998 gsxr 750, just did an oil change 2 weeks ago, oil level is perfect, but lately the bike will shut down, CEL flashes F1 i think and the red light blinks. Now, it first started when i would do a catwalk, after bringing my front tire down it would stall, and i would hit the kill switch and bomb start it and keep going. Now tonight i was bringing up the revs merging on the highway and it did it again. Anyone have any idea what the hell could be going on? Thanks.
