So hopefully I can get some help here (or Andy might delete the thread for being an overused topic
)
Ok I bought an MC21, which has what I believe are ZXR400 USD forks. The brake discs have been changed to VFR400 296mm discs. This seemed all good, but I have encounterd 3 problems, 2 of which I believe can be fixed by fabricating a bracket.
1. The caliper mounts on the ZXR400 forks position the NSR calipers too high on the disc. I.e. only 2/3 of the pad makes contact with the larger-that-standard vfr disc.I assume this problem is common? Will a bracket be able to successfully reposition the caliper?
2. The discs do not sit central between the two pads. I assume this is an offset issue with either the discs or forks? The bracket in my mind should fix this, but I also believe it could be related to problem 3.
3. The front axle that has been used is (in my uneducated eyes) too short for the wheel and forks. The end with the holes (that a thin bar can be passed through to aid with the removal of the axle) sits almost flush with the side of the pinch-clamp area of the fork. The axle also appears to be sporting some home made spacers, which I think could contribute to the wheel not centreing correctly. Could the axle be replaced with a standard ZXR400 model and still work fine? Or should I just have new spacers made?
Has anyone done this conversion and had the same problems? How did you get around them?
