ok heres the sequence of events.
bike ran fine but had a slipping clutch. took the clutch cover off, replaced clutch springs with stiffer ones, put clutch cover back on. replaced fluids. kicked it on and a distinct knock, like the normal engine noise but louder, comming from around the clutch cover.
bit the bullet and tore it down again.
took the entire clutch side assembly apart, checked the oil for metal shavings, found very few. checked everything and didnt notice anything broken, scratched, nothing. threw it back together...still the damn knock. checked compression even across the board.
i let it idle for about 8 minutes, idled fine, started first kick. ran it around for about 5 minutes still ran hard. but the "knock" is still there.
where is the noise commin from
