    2005 r12 engine problem cant figure out

    it runs fine all day long if you keep it under 4500rpm try and give it more and it starts missing almost like a rev limiter. but its not. or you can grab alot of throttle and it will shoot up to 5500 and start missing without going over 5000rpm either way and no codes??????????

    Sounds like a plug mis-fire to me... I would put a fresh set of NGK's, and see if that cures the issue.
