r6rider04 Posted January 18, 2006 Report Posted January 18, 2006 I was riding around in second, hit a small jump and started to turn around. When this knocking/clunking sound started , at first it sounded like either the magneto was loose or maybe the clutch, but after romoving both covers i could rule those two out. So it has to be internal, any ideas what may have happened. just put in a new HOTRODS long rod +4 crank last january, so i'm thinking its not that. Tranny? what could have let go in there? i'm pulling the motor in about an hour or so . Any feedback would be greatly appreciated. Thanks, Brian Quote
fast87 Posted January 18, 2006 Report Posted January 18, 2006 try to recreate this sound by rolling it in neutral...make sure its not the chain, pull the head first to see what you can see...if its coming apart anyway it doesnt matter the order you remove parts, good luck and let us know what the problem was ~Mark~ Quote
RIPPEN Posted January 19, 2006 Report Posted January 19, 2006 Sounds like the exact same thing that happend to a buddy of mine When we pulled his apart we found a piston that was trashed.... Like fast87 said check the obvious simple things first then I would go for the head and jugs. RIPPEN Quote
Shee-Male Posted January 19, 2006 Report Posted January 19, 2006 gaskets are cheap, pull the jugs and make sure everything is ok, could be a peice of piston getting between the rod and the case Quote
crazywheelerman365 Posted January 19, 2006 Report Posted January 19, 2006 The claw washer and sir clip popped off my idler gear behind the clutch basket once and made a shity noise that sounded like a piston gone haywire! dont rule this area out.. Quote

r6rider04 Posted January 19, 2006 Author Report Posted January 19, 2006 (edited) well i just came in from garage..... and the verdict is..........no fu**ing idea checked everything. split the cases and everything looks good. all crank bearings good all bearings associated with tranny are good, nothing loose or broken. the only thing i found inside was the o-ring on the stator side of the crank shaft had broken and the broken piece was collected on the bottom half of the case (so the bearing is spining freely). and inside the clutch cover there is a collar that holds the bearing for the main shaft of the tranny in place, and one of those screws was missing. But there is nothing i can see that would be making the noise that i heard. sorry this is so long but were can i find a replacment o-ring for the crank bearings? thanks, Brian Edited January 19, 2006 by r6rider04 Quote
r6rider04 Posted January 19, 2006 Author Report Posted January 19, 2006 oh and the whole top end is good everything still looks new, just carbon on the pistons and head everything looks normal Quote
crazywheelerman365 Posted January 20, 2006 Report Posted January 20, 2006 I dont suppose you strained the oil when you split the case ? The culprit could be layin in the bucket of old oil? Quote
sandornothing Posted January 20, 2006 Report Posted January 20, 2006 This may not be the answer you are looking for, but I ride with a whole pack of banshees.Some make funny noises and some dont. Mine has had a clunking noise (at idle) since i brought it home. Quote
