Ok I have a quick question for ya guys. Heres what happened, my sprocket retaining ring failed to hold the nut in place which resulted in the nut backing off and oil leaking on to the chain and flinging all over the place. My question is, Is this a normal result in the nut loosining up or do I have bigger problems? And can i just tighten up the nut to stop the leak? This is on my 2003 WR450. Thanks guys!
