I did a track day again yesterday on my MC21 R and it was really great fun. However, I felt I was losing out in the braking to bigger sports bikes. The main issue seems to be the initial bite of the brakes and the dive of the suspension, which really upsets the bike and throws a lot of weight on your wrists and the bars (may be partly my riding style). My plan is to rebuild all of the calipers and change the pads and lines, but also feel the font forks maybe need setting up for me. So here are my questions.

1. What would be the best (easiest and most cost efficient) improvement for the front end?

2. Are up rated spring available for the R spec forks?

3. Will MC28 SP forks fit and if so do they need the calipers from an MC28?

Lots of questions I know, but I would welcome any other comments too, as the track lark is great fun and I want to make some improvemenst next time and show the big boys that the strokers can still do the business

THanks.

Easy, replace the oil with the correct amount of made up (15w and 10w 50/50 mix) 12.5w oil, the difference is night and day.

As a racer I'm not fast by anyones measure but I can hang in the fast group at 15st with 60odd bhp runnning R fork set up as above with no worries.
They don't bottom out, I can sail past 400's I race against with ease and TD boys on 600's or bigger are just cannon fodder

Have you ever changed the fork oil? Probably worth trying fresh oil, heavier weight oil or raising the oil height before you start spending money.

All mc28 forks will require different calipers and the 28sp forks are probably the hardest to get hold of, 21sp forks can be picked up easier and cheaper and give you a bit of adjustability over the r forks.

When I drained the oil from my forks I got a of light grey watery mush that might have passed for rat sick.

Amazing the difference having fresh oil in your forks rather than 20 year old gravy

Thanks for the tips chaps. Sounds like I need to pull the forks off and give them a fresh-n-up. The rear also sits a bit low, so that may benefit from being looked at too.

A pair of paddock stands may be in order. Is there something lat lifts from the footpegs so you can get the shock out?

ABBA stand is pretty damn good. I originally purchsed mine for my Trumpet Triple R and then modded it for the NSR. I am sure that they do the corect adaptors though.
It's so easy to use and is very stable.

I got some adaptors for the NSR, if they havnt kept a record of the sizes you will have to send them over. Its basically a cup that sits over one end of swingarm bolt and a pin that goes in the other, good bit of kit if you have to remove forks or shock.
