I’ve just rebuilt my forks off a Kawasaki KLX300 (Kayaba 43mm USD) with White Brothers Bushes part nos 29-408 and 29-404 and on the outer bushing I noticed that it was still loose around the fork tube when the gap was squeezed together, I assembled it anyway to see if it would tighten up but the assembled fork still had way too much play. I have measured the fork tube diameter against a new one and there is no wear.
In comparing the old and new bushes I noticed the code numbers are different – DD3C 9J on the old and DD3Z 3F on the new, can you help me interpret these and do they explain why I am getting play in the forks. Any help in what the problem might be or what else I can check would be appreciated.
Thanks for any help
