In case you guys fall asleep before ya get to my version of what the rules SHOULD be. I copied and pasted them so you can read them right here. Bear in mind that I ride a big 'ol Trail bike. I'm not the kid that whooped everybody on the KLX140 though. I'm a +40 Vet Class rider. I do like to show up and ride/race though. It's fun, and it helps keep the scene afloat-- that's what we all have to keep in mind here.
In the serious bigger races, and money races, I agree with Justin. 12 inch, open cradle, etc... I agree that a 150R is way too much bike in the pit bike races. We differ when it comes to letting the bigger bikes into random races where there aren't alot of classes, and alot of dis-similar bike types all get lumped together.
The race in question had 9 entries. It was actually called OPEN pit bike. There were 6 12 inch Mod bikes, two CRF150F's (one being me), and a lightning fast kid on a close to stock KLX140L. I got 6th, the other 150F got 8th, and the kid on the 140L won, which isn't suprising because the kid is a local A rider.
Now-- I agree that the bigger wheels are definitely an advantage, but more or less on big bike tracks with big bumps and ruts. Not so much on the perfectly groomed track we ran that night. Also-- I can assure you that the big trail bikes don't have more than 12 horse stock (I know that the two 150F's were bone stock. Not sure about the 140L). BUT! They weigh 220-240 lbs! I know alot of the mod 110's are doing 15-20 horse, and weigh half that.
Also-- I'm not trying to start another what IS or ISN'T a pit bike war again on here. I'm buds with Justin for sure. We're just discussing in an intelligent fashion a topic of pit bike rules here. We have to keep the rules (if there were any) in line with what bikes are readily available, and what the current trends are in our sport/hobby. We can't do what we did in 2005, b/c the scene is changing and evolving. The bigger trail bikes are becoming really popular in our region (Ohio) b/c they're everywhere for sale, cheap, fun to ride, super reliable, and they don't need $5000 into them to be raceable. It only makes sense to run them-- no?
Well- here are the rules as Mr. Luckystar would have them. Lemme know what ya think.
Stock 10-- No engine mods, Chassis mods limited to tall seat, bars, shock, fork internals. Pipe allowed on 50cc bikes. 70cc must run stock exhuast.
Open 10-- Anything goes.
Stock 12-- No engine mods, stock pipe. Chassis mods limited to tall seat, bars, shock, fork internals. 4th gear drums allowed on pre '10 KLX110's. (Every manufacturer but Suzuki has a 110 now!)
Open 12-- Anything goes.
Stock 16-- No mods other than shock, and fork internals. (Maybe let the 125's have pipes, but no pipes for KLX140's or CRF150F's? Just to try and get some parity for the displacement advantage of the 140 ind 150F? The 150 is one heavy beast though! Let XR100's go to 120cc's and run a pipe?)
Open 16-- Anything goes. NO 150R's.
Vet-- +40, Stock 16 rules.
Youth-- 12 and under. Stock 10 and Stock 12 bikes only.
