I just picked up a used Ohlins that Im hoping to get on before the end of the month and want to check the ride height.

Run the shock length at 320mm eye to eye.

Start by running the forks caps flush with the upper triple. Lower the forks into the triples as you get used to it/faster.

I am going to throw a set of Pirelli Slicks or Supercorsas on.

Does anyone know if I have to change anything in the setup?

Thanks.

Nope.....................

You want to run the forks in the triples to get more trail out of the bike. You still need to do it with the Pirelli's or the Michelin's

Your forgeting about the top out springs. When measuring the fork length you want to dial all of the spring preload in so the top out springs get overwhelmed and they will no longer be a factor in the measured length of the fork. That being said they still may end up a bit different, the 1K forks have 1.0+kg springs and the 750 has .90kg springs. They will load the top out springs a little bit differently. The only way to tell for sure is to have two people hold on to the fork and "stretch" it out as far as possible and then measure or take the springs out and measure.

So I made that call and as luck would have it Mike doesnt recommend GSXR1k forks on the 750. He thinks they're too beefy for my bike and highly recommends I stick with OEM.

So here I sit wondering which way I should go. Im not racing this yr so Im not in any real hurry (that might change tho for the CCS Barber round in August) so Im thinking about waiting on someone who's selling a set of STOCK 750 revalved or 25MM kitted forks.

I could send them to Mike for his $700 revalve (includes Ohlins 20MM kit) or LE for their $600 revalve but in the past few months Ive seen some good deals come n go on 25MM kitted forks for about that or a lil more including the forks. I know how I am and it'll just piss me off if I send them out and then run into a great deal soon afterwards.

I have been re-shimming (not re-valving) the GSXR600-750 since they came out. They are a great set of forks they just have the adjustment ranges all screwed up. For example there is hardly any rebound. While I am in there I remove the bottoming cones so you can trail brake the bike and still have some feel and of course a spring package that suits the rider. This service is $350 and that includes springs.

I have guys winning Expert races on a setup like this.

Suspension setup is 90% geometry and springs. The fluid and valves are only there to keep the springs under control

This post was from almost a year ago when Dunlop was still using the 190/60....
