WTB: Front rotor ZR250/ZZR250

[Devil]

Anyone got one of these lying around somewhere?

[MrMelon]

What'd you do now?!

[Devil]

Haha! Nah, mines warped, always has been. Irritating.
Not a disc-locking incident fortunately

How badly warped is it? Some warping can be fixed - you need a felt-tipped marker and a big adjustable spanner. Spin the front wheel with the tyre off the ground, and the marker pen held against the fork leg so it just touches the disk at the points where it wobbles outwards. Then you can use the big spanner (with cardboard under the jaws) to bend the disk in and out as required. Then repeat as necessary. I've used this with success on my VF500 and on a diamond sawblade that I jammed a ceramic tile in the side off. OOoops...
Small warpages can be lessened by adding/removing spacers between the disk and the mounts on some bikes. My VF had a badly worn disk on the front due to the caliper slides sticking, and I found out that NR/NSR(??)250 disks were the same apart from being drilled. Unfortunately, all the right-hand ones at the wreckers were warped, so I had to fit two left-hand ones, one of which was slightly warped. I got rid of almost all the warping by swapping around the spacers under the mounting points. They looked like they were made of gasket paper, so I made some extra ones from this.
Another method is to take it off, park it on a hard, flat surface (like custom wood on concrete, or a flat piece of steel), and with a block on top of the disk, pound it with a BIG hammer. Helps if you heat it first too.

Find out whether other model's disks will fit - a wrecker or Kawasaki enthusiast should know this.

Plenty.

No thanks

Good idea, ill have a look at that.

yer so far the only lead I have is the ZZR250 disc, most people hear ZR250 and go ".........you mean a ZXR250?". From Frosty's opinion it looks like a ZZR front end. But if anyone has any suggestions... anyone know if the ZZR400's front rotor is larger than the ZZR250's?

Guess what, I have a new disc if your keen. Thanks
