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?

Thanks for posting the 2003 LW Sportsman rules. I agree that your CR500 was legal in that class. The discussion regarding singles gets a little confusing, but my understanding of the rules was that singles could use any frame/engine combo, but that Spondon, Tigcraft etc hybrids & race bikes such as Duc Supermono, Wood-Rotax, etc were not permitted in the class, and were bumped to Supersingles (and GP Singles before that class was created) MW Sptsmn (Ultra LW Sprbike now), LW GP, etc. But these rules could be interpreted to mean that even street-framed based hybrids over 500cc like an SRX/Hawk would have been excluded. Looks like a smaller non-production hybrid e.g. CRF450/TZ could have run in the class.
The CCS LW sportsman & WERA Clubman rules convinced me to build a production based MuZ vs an exotic hybrid, so I'd have more classes to run...well I got to run one CCS race, ROC 2003, on the newly completed MZ and then the class went away for '04 :(
Just for comparison, here are the WERA Clubman class rules. Sportsman (and then later LW Sportsman) was pretty much CCS's version of Clubman.
They're pretty permissive about hybrid singles, but specify no Duc Supermonos. I think CCS's 2003 Sptsmn rules were more equitable since it treated racing framed hybrids the same as the purpose-built racers, but the language needs to be clarified, i.e. does "production" frame include one produced to be used for racing only, or a frame produced to be used on a "street" motorcycle?
