03 954RR Rear Tire Chatter Please Help

Ok I just totally rebulit my 954 from the ground up. Last year my chain broke an bound up on front sprocket an blew tranny. So when I rebuilt I bought another motor to replace my old one. I put everything back to the way it was before. So now when I ride an I'm under hard acceleration an lift of throttle or tap rear brake I get a lot of rear tire chatter. It gets real hairy in the turns I gotta pull clutch in for it to stop. I pulled rear wheel check bearings, cush drive rubbers, sprocket, tire alignment everything. I don't get the wheel chatter I'm thinkin its the clutch. Anybody have any thoughts?? Please help before I wreck this thing in a turn.

Did you find out what caused the chain to break?
Is there any movement in the swingarm bearings?
Are all the spacers on the rear axle in the correct positions - particularly the sprocket carrier spacer and the bearing spacer inside the wheel?

Yea bad link from a cheap chain. I just put in new swing arm bearings. I will have to check if the spacers are on the correct sides an dont have them reversed. Could those spacers if they were reversed really cause wheel chatter?

Do you mean this has only been a problem since you changed the swingarm bearings?
Did you have any trouble installing them or pulling the old ones?
If the spacers aren't right it could cause all sorts of problems, that's why I asked about them. If the sprocket carrier spacer or centre wheel spacer are missing or not correct then the wheel might be floating on the bearings.

Re: 03 954RR Rear Tire Chatter Please Help

Have we ruled out the possibility that the replacement motor is faulty in some respect to driveline backlash? I hope it's just a spacer issue as BladeRacer suggested. Let us know what you find.

Yes this problem arose as soon as the rebuild was complete. No problem with the swing arm bearings when we pulled them an reinstalled them we used a shop press to do them. So Im gonna look into the spacers an make sure i have them on the correct sides.

No what do you mean by that? Driveline backlash? Does that have something to do with the clucth or tranny? Could you please elaborate more an what you mean by driveline backlash. Thanks

Re: 03 954RR Rear Tire Chatter Please Help

Usually I would say too much rear preload. The rebuild could be a red herring? Check the preload setting, my guess is it is on max but you're a lighter rider. Set it to factory. While you're in the area reset the dampers to factory settings to get a decent base line.

That's what you feel when there is excessive play in the driveline. Like the dampers in the rear wheel when they wear out. The driveline gets sloppy. I'm used to calling it backlash. I was just wondering if the tranny/clutch items were in good condition and there are no issues INSIDE the replacement engine causing the chatter. Did you say it goes away when you pull the clutch in? That would lead me to believe it may be an internal issue.

My first thought as well.

If the bike isn't braking properly, you don't start by rebuilding the engine.

Re: 03 954RR Rear Tire Chatter Please Help

I wonder, could the new engine have had a slipper clutch fitted??

Red Herring?? Whats that? No Im not a light rider lol I weigh like 230. My suspension was soft, we thought that was the issue too so we cranked up the damper to stiffer an its still there. I just checked my spacers an they are on the correct sides. I will have to try setting it back to stock. Any body know what the stock settings are??
