Prime Posted July 29, 2018 Share Posted July 29, 2018 (edited) (Thanks to admin for moving my post appreciated) Hi guys and gals A mate had a bandit 12 motor run fine from what I can remember, he changed the cam chain guide as it was broken (was running fine before he took the head off and found this issues) after fixing this I don’t remember the engine being ran back up after that in my presence I have now acquired the motor and it has a bad noise from what sounds like the gear box (front sprocket side id personally say) Before parting the crank casing I took the clutch basket etc out and found the roller bearing had ovaled great I thought however this didn’t change anything I took the basket etc out once again and for a second ran up the engine The noise had gone completely upon doing this (clutch all seems fine upon visual inspection) Now I have the crank cases apart as I was thinking it was the bearings within the gearbox however they all seem fine I haven’t measured anything to see if there within spec according the the manual im just wondering if anyone had any experience with what ever I’m chasing Appreciate any input Thanks Edited July 29, 2018 by Prime Quote Link to comment
wraith Posted July 29, 2018 Share Posted July 29, 2018 You could always ask, say @vizman to move it over for you Sorry can't help with the engine bit. Quote Link to comment
Captain Chaos Posted July 29, 2018 Share Posted July 29, 2018 You had it running without the clutch basket and the noise was gone? The clutch also drives the oil pump and the generator. Maybe the generator driven sprocket is loose? Quote Link to comment

Gsxrsam Posted August 1, 2018 Share Posted August 1, 2018 Bearing behind sprocket is worth a check too........ Quote Link to comment
no class Posted August 2, 2018 Share Posted August 2, 2018 Basket was improperly installed !..... how the hell do you " oval " a roller bearing ???? Check the oil pump gear for damage ....and the alternator drive gear ..... that will be the one behind the clutch basket . 1 Quote Link to comment
