Banging into first

[b1k3rdude]

My Gen 1 makes a right big BANG noise as I put it in first. Is this normal and if not is it a known issue?

If your gear changes into 1st and 2nd require more force on the gear lever or even dont go in untill you feather the clutch then you have an easily fixable issue.

A known issue with Gen1's (as I found out recently when I diagnosed a gear change issue) is the clutch hub can become worn where the steel clutch plates hit against it  and also the basket where the friction plates hit against that.

I took the clutch out of the bike (complete) and then fashioned a small rubber block the same width as the slots in the clutch hub and some with fine grade (800 or 1000 I think) emery paper and dressed each slot till the wear marks from the plates were mostly gone.
