Pointy swing arm side play.

Mine was the same, I cranked it up (didn't use a torque wrench) until there was no play and the swingarm moved freely.

Transformed the feeling of the bike, got rid of the headshake and wobblyness mid corner!

but if you do that you stress frame. Better to take play out with shims.

I've checked a GSXR, an R6, a FZ1, and a CBR6 all with no play at all.

So have all SV's got this play?

Check your's tomorrow everyone, and report back

Mine doesn't. And I've got the back end apart so I've checked thoroughly. Only play is in the shock bottom bearing which was knackered. but it is curvy.

When the finnish? guy posted his findins my thoughts were that he was missing the end caps that curvy have and are about .5mm thick.

The roller bearings on a pointy have intergrated seals, hence the price.

I have a supplier trying to locate some for me at the right price, but when I quoted the number to him, he was a bit weary. Although the bearings are made in Germany, Suzuki may own the rights and may not let other dealers sell them with out a charge to Suzuki.

I was thinking shims, but still don't like the idea of the swing arm being a bearing surface.

As far as I can see there's no avoiding that, it's how it is on the curvy. Bearings like that can't provide any axial location.

Unless you machined swingarm down and fitted a thrust bearing each end.

I'm 100% confident that it won't put any excess stress on the frame, i'm sure they aren't manufactured to such a tight tolerance that a few extra lb/ft of torque will damage it.

[DavieSV]

so you recon that's what it is then?

Suzuki manufacturing tolerance + lack of proper bearing surface + lardy throwing it down the road, unlike the design brief = sloppy swing arm

ohh, I can hear the 'click clack' of loose swing arms being checked up & down the country

[yorkie_chris]

I'm 100% confident that if you bend something to take up 1mm of play it puts stress in it. It's a bit of metal, that's how it works...

Whether it will make any difference is another thing. Probably it won't hurt owt. But better to use a small shim to minimise the bending.

Out of curiosity, how much torque did you need?

It wont put any undue stress on the frame as it only bolts into one side, the threads may be under stress and the spacer tube may deform. the castle nut just secures the other side, don't over tighten that!

Must be alot to compress a tube axially by 1mm

But the bearings can slide so any pressure you put on the threads transfer straight through the spacer tube to the other side of the frame.
