I decided to do the starter upgrade on my '03 wr450. I was putting the cover back on and tightening the bolts and I cracked the cover. I don't really know what I did wrong but I must have not had everything lined up right. Anyhow, anybody have a cover lying around? Thanks, Huero Update, I looked and realized what I did wrong. I did not have the case cover pushed onto the starter enough. As a result, it bound up the case cover and when I tightened the bolts I cracked the cover.
