too_fazt Posted November 5, 2010 Report Share Posted November 5, 2010 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 Quote Link to comment Share on other sites More sharing options...

Nothing to worry about really, just check the reeds for wear. Quote Link to comment Share on other sites More sharing options...

too_fazt Posted November 6, 2010 Author Report Share Posted November 6, 2010 well mine doesnt make the same noise in the video. that one sounds more of a flapping noise. mine is more of a tick. after i did a little searching i realized the idler gear is not supposed to have any wobble to it. i had always assumed this was normal, after tearing into 3 different engines and them being the same. now why its making more noise now then before? i dont know. ill get a video of mine so u can compare to yours.

AKheathen Posted November 6, 2010 Report Share Posted November 6, 2010 now, keep in mind, i said "probably" I'd hate to see you go replacing a good basket, lol......you just need to pull the clutch discs and check the different plays. radial is the basket conical washer and cushions. wobbling is just the bushing. really, the basket doesn't need replacing until the fingers get real grooved, and makes your bike creep and jump in gear with the clutch released. that idler gear needs tightened up, though....
