Ok. My '01 VFR has been having rough engine problems on and off when ever it feels like. She pretty much rides fine, but then one day it feels like someone is tugging on the bike of my bike when holding a steady speed. You can feel the bogging when getting on the throttle and she'll die some times when I pull in the clutch. I'm sure my starter valves need to be sync but I'm sure they can be way off and still not make the engine run this bad, can it? I'm leaning more to fuel problems. Either the regulator or the EFI pump. You can hear the "prime whine" just fine and sounds the same everytime. I've heard a bad pump on a chevy. Sounds like crap. A guy I work with said he had the same problems with his minivan. It ended up being the pump. It would work fine, but then somedays it would run like crap. All opinions are welcome. Even the stupid ones.
