Hi, nice to be back. Camchain? Signs of wear, noise, how to check and replace? Any advice.
Pack your long johns away in the north!! Cheers.

Welcome back stranger....

Check the download page and find the K75-K100 Haynes manual. The procedure is very well explained in the chapter "Re-Assembly" starting at page 82.
If something is not clear ask for clarification.
This procedure can be done in about 4 hours (or less) and doesn't require to remove the engine. The biggest job will be to remove the bottom fairing.
Don't forget to mark the position of the Hall sensors before removing them.

Have fun.

Bert
