I had my first trip out on the 400/4 of 2016 a few days ago and I was quickly reminded that the front end does seem a bit under damped. Noticed it on the first few post rebuild rides last year, but having never owned a 400 before, I'm not sure what's 'normal' !
The forks were rebuilt with the rest of the bike last year with the old springs and fresh 10wt oil, but there does seem to be a bit of bounce to the front end - should I be looking to move to 15wt oil, or trying more volume of exiting oil ? anything else to be checking ?
Also noticed a very minor weep of oil from n/s drain bolt, which had that horrible stripping thread feel when I attempted to nip it up a bit, so I'm pondering if I going to be able to helicoil without a complete strip of that fork leg - I'm guessing I'll have to to make sure there's no swarf from drill / tap for the insert ?
Thoughts and advice welcomed !
