n.wales_sherco_lad1 Posted November 7, 2005 Report Share Posted November 7, 2005 probably main bearings or piston rings. where about is the rattle coming from? Quote Link to comment Share on other sites More sharing options...
alan bechard Posted November 7, 2005 Report Share Posted November 7, 2005 Fill out your profile so we know where you are located and can refer you to someone possibly. Clutch in / Clutch out / under load / under deceleration / constant / intermittent????? Could be clutch, could be bearings, could be gears. Just too many variables, and not enough info, to give an accurate diagnosis. Quote Link to comment Share on other sites More sharing options...
howard wallace Posted November 7, 2005 Report Share Posted November 7, 2005 Does the rattle change when you pull the clutch in, or if you put the brakes on and load up the clutch.If it goes away, most likely rattle between the straight cut gears on the primary drive, and clutch basket. Nothing to worry about. Quote Link to comment Share on other sites More sharing options...
pete Posted November 7, 2005 Report Share Posted November 7, 2005 As stated above, more info needed! Mine rattled for a long time, and it was a woen clutch basket. It stopped when the clutch was pulled in. It also made a noise like a machine gun when the main bearings gave up and split, and a lot of other things make a bike rattle as well! Pete.

austini Posted November 8, 2005 Report Share Posted November 8, 2005 My 250 (2000) also rattles from the top end, I have changed the clutch basket (now the rubberised one), main bearings,rings etc: so now i'm thinking piston slap....... is this common for a sherco after 4 seasons?

trial_master Posted November 10, 2005 Report Share Posted November 10, 2005 My 03 290 was making a tapping sound when reved in neutral or in gear, clutch in or out. I thought it was an engine problem, but turned out to be the waterpump shaft! The tapping/pinging sound was coming from the bike overheating. (it sounded a bit like an old diesel car) It cost about Quote Link to comment Share on other sites More sharing options...
