Alright, I put this up before and got some good responses so here goes again........
72' Honda 350 twin that runs great accept for anything over 5000 rpm. Only has a hair over 10,000 miles on it.
- Air boxes replaced with stacks
- megaphone exhaust with cherry-bomb style baffles
- Timing and (new) points are spot on, mechanical advance working fine
- valves set to stock spec.
- fuel tank flushed, fuel flow is good
I didn't ride it much before I did anything to it because the tires were junk so I can't say if it did this before the air boxes and exhaust got pulled.
I drilled the jets once, approx. .003 bigger and then it only had a tiny bit of a miss over 5000 rpm. I drilled them again and I'm back to where I started.
Would a stretched timming chain be at fault?? I've heard these were known for this. Or did I go too big on the jets?? This thing is driving me nuts and I'm running out of warm weather. HELP!!!
