Engine rough at 3200rpm?

mike270 · 09-12-2003, 12:36 AM

I have noticed lately that my engine seems to run roughly at almost exactly 3200rpm. Only happens while cruising at that rpm, so little throttle. But happens in every gear. Happens at 50mph in 4th and 70mph in 5th.

No CEL's. Power feels good. Just when slowly accelerating through the point it goes smooth.....rough.....smooth. Almost feels like the roughness is coming through frame but since it happens in all gears. Its hard to notice unless you kindof look for it. I notice all the time now though.

I have done the grounding mod as well. Only other mods are kartboy ss/bushings, and ganzflow intake.

Any ideas? It seems like it might just be normal operation but I only noticed it lately so I wanted to make sure.

Mine is different though.

Mine only happens when cruising at a constant rpm. Almost feels like the engine is resonating at that rpm or something.
