Thought the Suzukis use the Ward 2-valve heads to gain additional displacement over the 4-valve, 4-cylinder displacement rule.

I'm most interested in how Rob does with the ZX14 in 2007. I'm a bit fuzzy on NHRA's Pro Stock rules; is the rulebook more equitable to 4 cylinder, 4-valves per cylinder motors in 2007?

I thought the exact same thing. In fact I had a discussion about that last night with a motor head friend of mine. Based on what I read on Muzzy's web site, I'd have to draw the conclusion that NHRA go their head out of their...well you know where...and things may be balancing out.
I have to think that Kaw and Rob wouldn't venture down a path of pointless frustration...let's hope not anyway...
Should be a good summer for guys like us Bob!

Do not Suzis rule prostock and top fuel these days?
No. S&S v-twins that resemble Harleys rule ProStock and Pumas that resemble Kawasakis rule Top Fuel.

But I did find this link among many via Google: NHRA Pro Stock Motorcycle Adjustments
At www.nhra.com/aboutnhr/classes.htm I learned that:
"Pro Stock Motorcycle
Pro Stock Motorcycles have differing weights depending on engine combination - 575 pounds for Kawasaki, 590 for 92-cid Suzuki, 615 for 101-cid Suzuki, and 615 for Harley-Davidson and V-Twin, including rider - and have a maximum wheelbase of 70 inches. Bikes must be 1998 or later models and retain their stock appearance, including a front fender, simulated headlight and taillight, and manufacturer identification on both sides. The engine and body make must be the same. All motorcycles must pass NHRA body inspection prior to competition."
Well, seeing what's out on the track in this class, the rules must be cast in jello. Where's my magnifying glass anyway?
