The slicks raise the front by 8mm and the rear by around 12mm over standard tyre sizes. So overall your c of g is now higher and possibly more forwards than previous.
Dropping just the front or trying settings that 'work' for the NSR won't really work. It's not really an NSR anymore.
Work through it methodically to find what works for you.
Do you know if the ZXR forks have changed the offset of the forks / front axle at all?
Thanks Greggo. Good point there. It's true that it's not a true NSR anymore, but reference points for setup are handy.
Thanks for the tyre measurements. I am using an RVF 3.5 front wheel though, was your 8mm for a 3.0 inch front wheel? The rear is the standard Magtek 4.5, so your 12mm is probably accurate there.
The ZXR triples have approx. 35mm offset (will need to confirm that when I get home - it may be slightly less at around 32mm). So my theory was to get a general setting close to what is know to work for the chassis, then make changes from there.
For example, if I wound down the rear ride height by 12mm to what would have been the max height with stock tyres, then dropped the front approx. 32mm (ZXR forks already 24mm longer than NSR), would I achieve the same rake and wheelbase of the NSR with standard forks and an ohlins rear shock?
I know that the trail is not so simple to correct, though reducing the rake further could balance that right?
Does anyone have the MC21 standard rake, trail, wheelbase and offset figures?
