If you're gonna propose something, then you've got to open it up.LW Sportsman would have been the class for my three cylinder Kawasaki street bike racer project. Would have been very competitive, and should be. Look at the original rules and try to put something together based on that.
Under the previous rules, air cooled two strokes up to 500cc were allowed. H2 would not have been allowed as it's a 750. That would have been legal for MW Sportsman. As would have older CB750's in MW Sportsman.The trick is if you're going to try to rewrite a rule, you need to cover all the bases. I got the LW Sportsman rules changed to allow H1's in it as RD's were allowed. In vintage racing all around the country, most organizations recognize "Formula 500" as a class. Under CCS's previous structure, the cut off was like 450cc's or something.If you're gonna remake LW Sportsman, you'll have to take into account what bikes, over a long span of manufacturer builds, could be raced in it...then you're gonna need to figure out how the other racing classes would be affected...and rewrite those rules too.
6.5 SPORTSMAN - Sportsman machines are based upon production models, sold by manufacturers and their dealersin North America for street use. Proof of compliance rests with the competitor entering the motorcycle. Singlecylinder machines are exempt from street use requirements. Single cylinder 2 stroke GP road race machines are notallowed in this class. All machines must have unaltered VIN numbers.6.5.1 Production machines not sold by manufacturers and their dealers for street use in North America via normalcommercial channels may be approved on an individual basis . CCS will maintain a list of non-standardapproved models and that list will be available at each event from the Race Director.6.5.2. All machines must meet the equipment standards of Section 5, as well as the following:A. Frame, head(s), cylinders, and engine cases must be from the same production model motorcycle.(1.) Single cylinder motorcycles may use any frame and engine in Middleweight Sportsman.B. The frame must be as originally supplied by the manufacturer on the approved model. Strengtheninggussets or tubes may be added. Only brackets or tubes not supporting suspension, engine, or drive linecomponents may be removed. Swing arms may be modified or replaced and rear shocks may be replaced orrelocated. Single cylinder motorcycles are excluded from this restriction.C. Reducing engine size of machines from stock displacement to meet Sportsman class displacement limits isnot allowed.D. Fairings that meet the requirements of Section 5 may be used.E. Liquid cooling is not allowed unless original equipment on the model being used.F. Original type of induction system must be retained. If a machine originally was sold with fuel injection, thenit must remain fuel injected. If the machine originally came with carburetors, then it must use carburetors,however they need not be the original type or size.6.5.3- Sportsman Class displacement limits are absolute and are set as follows:LIGHTWEIGHT SPORTSMAN (Amateur & Expert Divisions)Single cylinder, unlimited displacement, production frameSingle cylinder, up to 500cc, unlimited frameTwo stroke, liquid cooled, up to 410ccTwo stroke, air cooled, up to 550ccTwin cylinder, air cooled, non-desmodromic valves up to 700ccTwin cylinder, air cooled, desmodromic valves, up to 650ccTwin cylinder, air cooled, 2 valve, push rod, up to 895ccTwin cylinder, liquid cooled, up to 515ccFour cylinder, air cooled, 2 valve, up to 625ccFour cylinder, liquid cooled, up 410cc
You may be right, the old rules might need some refining, but don't you think a Hybrid H2 in LW Sportsman is cherrypicking ;D? O.K....let's discuss it, but meanwhile we need to get CCS on board.
Here is the LWSM rules from the 2003 rules:I'm up for a new class as long as my CR500 is legal (It's a water cooled 2-stroke, which would be limited to 410cc, but it is a single cylinder "production" frame, which would be unlimited. The LWSB rules are this way as well, I've always run it as an "unlimited single" and not a "two-stroke")If you really intend for a new class to accomidate singles and other LWSM bikes, LWSM is more restrictive than SuperSingles, which allows the Supermonos and Tigcrafts and homebuilt hybrids. Should they be allowed into the new class as well?-z.
Like I stated above, a 750 a/c two stroke was legal for MWSM...that's the H2. H1 is a 500.Still has to use a production frame, remember.Regardless, I raced a 1969 Honda 750 at Daytona (air cooled four stroke) and set the vintage lap record with the previous chicane. I would have been pretty competitive in Thunderbike...even though that bike would have been a MWSM bike.With what I am doing to the H1, I fully expected to go faster than I did on the CB750. Still a production frame with dual shocks, wire wheels, etc.As for getting CCS on board...You've got to show where the numbers of riders will come from.
The numbers would presumably come from the hordes of (former)LW Sportsman & Supersingles riders that find themselves bumped into Ultra LW Sbike w/ the MW Sptsmn bikes.
