Ive been reading through forums all over the internet trying to figure out my problem for weeks now with no success. Hoping that someone might have something that could either point me in the right direction of what to try next, or point out the obvious. 1982 CB750SC with 25,000 miles, Runs great until I hit about 5500-6000RPM. If I can get it around 7000 RPMs it looses all power and feels like its going to die. If you ride it like a chainsaw with bad gas you can get it to almost half assedly run under lode past 7000+rpms
- Stock air filter
- OEM 4 to 4 exhaust
- valve clearance is in tolerance of FSM
- All 4 cylinders test at 150
- fuel flow is fine
- Battery/ charging system is in working order
I'll put up a picture of my plugs after driving 100+ miles around town.(sorry for the image quality) Cylinder #1 looks rich, but I think the rest look fine.
Any help is much appreciated.
