hi gfact46,

thanks for the feedback, sounds like something and nothing then, unless we hear otherwise. can't say i've had a reason to rev it out as you described as i haven't checked the rc valve openings but i will do soon enough when i get around to it as i'm getting my mc21 ready for an mot and having plenty of fiddly little jobs to do on that first. i'll send you a pm when i have a look.

i think you should post the question as it is a good one. you'll probably get a better more reliable answer plus i live around people that don't share our love of blue smoke and they wouldn't be best pleased me reving it out to 9000rpm.

have you posted any pictures yet on the site. i will when i have sourced a hugger for mine.

thanks
