The drive is always run clean, unfortunate, as a used bike, I can't tell how many miles -I've done 2000 on this chain anyway.
..seems he may have been suggesting that a chain change MAY result in me finding out I need a cluster too.
It may skip...it may not, I believe I will try the new chain only -see IF it will run and not skip.
If it does -a new cluster, if not and it runs fine, I'll do the cluster later.
Thanks for the input.
