I just noticed that Lightweight F40 allows a 800cc, watercooled, 4-valve, (non desmo) V-twin. What bike are they talking about? They only allow LWSB to be 700cc. ??? I know. I ask too many stupid questions.
Remember Kevin, there is no stupid questions. Just stupid people. ;D
My guess is that Forumula 40 goes by sportsman rules and not superbike rules. ;D
BTW gonna be at RA? If so hope to see ya there. (If lucky I'll have teh YZF750 out there to play with Kimmie ;D. OTherwise I'll have to beat her with the F2 in HWSS ;D )
Maybe a Suzuki VX 800 ??? If I was you I'd be worrying more about the part that says "Twin cylinder,air cooled,Unlimited displacement" ;D

LW40 allows Thunderbikes to compete.
Oh my god! How you doing Jim? Am I gonna see you at Road Am? I sure hope so. I missed racing you last year.

800cc WATER COOLED 4-VALVE V-twin?
Hi Kevin! Yea, I'll be at RA. I finally got my credit cards paid off from the '02 season :o and I've applied for a few more so I'm ready for '04!!!!!!!
Besides, when I saw we got a lightweight class for us "mature" racers I couldn't resist, I knew I wouldn't have to race Eddie ;D (unless he's added a small Suzuki to his stable).
See you on the grid at RA!

So that means that an 1100cc horizontally opposed twin with built in ground feelers(otherwise known as cylinder heads) could run? Could I get bonus points for getting off of it and just letting it spin around in circles, pivoting on a cyclinder head?

;D ;D ;D
Oh God, I raced one of those air head things many years ago. Biggest worry is sticking that head into the pavement and levering the front wheel off the ground. It's not a good feeling! :o
I've always wanted to drag that old behemoth out again just for kicks but couldn't talk the owner into it. Quit trying years ago. I think he still has the thing. Hmmmm..... ;D ;D ;D
As per 2004n rulebook
All machines legal for LWSS, LWSB, LWGP, or Thunderbike are legal for LW40.
Yes Kevin, 800cc liquid cooled, 4 valve per cylinder non desmo bikes are legal.

Isn't 700cc the limit in LWSB and LWGP?
Just looked at the rule book. 800cc is the Middleweight SB and GP V-twin 4 valve limit. What gives?

I guess I should rephrase the question. What brand and model of bike would fall into this catagory? (800cc V-twin)
I think I'll destroke a TL1000. ;D
Bored and stroked SV?
SV too current... not legal
SV's are legal, as are all Thunderbikes, that is why the rules read the way they do.
Good luck, have fun!
Doh! I was thinking Ultra LW Superbike when I wrote that...sorry!
