Need help from some of you mudder guys. I pushed my bike pretty hard this weekend at a derby. I found that in 4wd with diff lock on I would hear clunking in the front diff and the front right tire would not engage as I would expect it too. Is this normal. Now let me explain this was in a mudhole and under heavy load not under regular conditions. Does the front diff slip? I think I've heard guys adjusting the front diff cable as it stretches. Could this be the problem. What is the proper way to test that the diff lock is working properly? Sorry new to Kawi diffs have not worked with adjusting them at all. Came off a polaris. Thanks for the replies.
