I have an 88 blaster and the bump stop has fully disintegrated over the years on the rear shock. I went to my Yamaha dealer and they no longer make them and I have searched all over for them on ebay. My two options are to find a new bump stop or have someone help me find works or elka shocks for a reasonable price. I have a 400ex shock but wasn't happy that I would have to cut the rear fender.
