ccs trial run?

[britx303]

hey everyone,i currently race elseWera and I am giving a serious thought to trying ccs at summit next weekend.i race an fzr400/600,and cannot figure where it would best fit in besides thunderbike(I believe).yes ive read through the rulebook,but we know how that goes.also can I show up with my current orgs license as eligibility,or contact someone ahead of time?thanks in advance!

Truthfully, its not legal in Thunderbike either. Because it is a hybrid of FZR400/FZR600 then it would fit into the GP and GT class. Since it displaces 600(599) then it would be legal for the middleweight stuff. In all due to the age it wouldn't be competitive against any of the middleweight machinery. CCS just isn't set up for older machinery built like what you have. CCS is typically geared for modern machinery.

What would make your machine a little more competitive is if the 600 motor was downsized to 565cc and then it would be legal in lightweight.

I think because of its age it can run in the LWGP, GTL and LWF40.

No it can't. LW GT or GP is up to 565cc. Haven't seen any exceptions for older bikes. The answer I have always been given is that the motor has always been intended as a middleweight so as long as it displaces 599 and not 565cc then it is middleweight. If something changes then I will be racing my 1991 FZR600 in GT lights. I don't see that happening because then my 2000 Ducati 748 would be legal too.

dang I don't know why I thought thunderbike.i could have sworn that's what I was told to run it in when I inquired last year. great, now I need a 400 engine to put back in.

[roadracer162]

Or just run it and don't tell anyone. It's only me that will identify the difference in the motor.

Am I reading this wrong?

[britx303]

Is formula 40 based on the racers age? Im 4 years too early,if so

[roadracer162]

Unless they have changed it to allow these hybrid bikes this is my take of it. LW formula 40 includes a couple of classes and what you have stated are the absolutes. Thunderbike and LW GP are inclusive to the LW F40 class. LW F40 was not a stand alone class. The portion stating liquid cooled four cylinder up to 650cc is from the Thunderbike class when used in a 600 frame. It is not legal to put a FZR600 motor into a FZR400 frame. Thunderbike rules state same frame, cases and head from that model bike.

LW GP state liquid cooled inline four up to 565cc. So if you follow LW GP rules where a motor swap is allowed then the 565 cc limit comes into play. If you follow Thunderbike rules then a motor swap is not allowed.

I must say I hope you are correct because I would love to use my FZR630cc motor in my FZR 400 frame. Of course the only class it will be legal for and have a chance is the LW F40 class.

ccs rulebook is grey with my bike plus I just got off the phone with my tire guy who also runs a 400/600,and as soon as I mentioned coming to ccs,he asked if im going to run it in thunderbike before I even mentioned the class. I think I need a ccs official
