Loose play in swingarm.

[mobil1]

Hi Gang.

I've a problem I think. When I've got the rear wheel off the ground I can lift the swingarm by about 5mm.

Is this natural or the suspension needs a set up? Or bearings?

I've had it all apart and checked things out and have also fitted a zx12r shock in. It's doing the same as with the new shock as it did with the old.

Help!! Pretty please.

Either a bushing or bearing gone bad. Start cycling the arm and find where movement stops. Usually the pivot at the frame but sometimes the bushing where the dogbones connect.

You might need another set of eyes to pinpoint it.

I found the issue. I hadn't torqued one of the dog bones up tight. Either the bolt or the nut seem to jump back a thread.
Luckily I had a spare bolt from a scrapper. All good now.

Cheers for the info tho. That will come in handy for sure at a later time.

I had the exact thing happen on my fz1(fazer) when i put a bmw shock on, it got hung up on the start of the major diameter. I thought i was stretching the bolt out when torquing it, and then it went pop and it tightened up.
