Would like to hear from active riders in TX

40cc

One of the nice things about building one of these things is you can placard it anyway you want. Since you are the builder, it's hard to argue against you. Aircraft homebuilders do it all the time. If an engine causes an airframe overspeed, you can derate it with a different prop or even write an RPM limit into the Operating manual. The homebuilder IS the manufacturer. Just bike friendly.
 
'walt...you nailed it...now, all we have to do is make sure our motorsport (like lite-aircrafting) is viewed as a serious adult endeavor...and that comes down to rider-behavior.

if you're only supposed to have 40cc, the only way to get "caught" with more displacement is if you're out there asking for trouble. we have to demonstrate a willingness to self-regulate & standardize.
 
That's pretty clear cut and easy to understand. Only problem is that 40cc thing since most gas engine kits are a minimum 49cc.

Well,

Most name-brand engine manufacturers supply engines in a range of sizes, and the kit & M-bike makers who use name-brand engines (GEBE, Stanton, and the like,) offer the whole range. However, the Chinese imports don't seem to have anything smaller than the 49cc available...

Part of the standards problem also rests with the states. Each one is implementing a different set of standards. In Texas, they are saying 40cc. In Arizona and apparently in several other locations, it is 48cc 2HP, and running at 20mph or less.

I think that IF we can develop enough numbers to influence more states to standardize on a common max engine size, we could start to see those same standards trickle down from the "low-cost" engine makers also.
