Had the bike out last weekend, it started ratcheting in first gear on launch. I did replace the chain and made sure it was tight. Its a really fast ratcheting in 1st. The bike is a 1441 2008. I thought I saw a thread a while ago saying it could be the clutch basket, but can"t find that thread/post.
The basket does have significant heat signature evidence at the back, browning discoloration, I will post a picture shortly. Could this be the cause? Anyway to check prior to replacing?
