...wow, that's a tough call...the S8 150 is an awesome ride...
..your states laws are like here in NC...
..it translates to a half-dozen citations if you get caught..and the fact that after that, you're no longer "invisible" to the po-po....they might take your ride, i dunno...
...speed limit for 49 cc scoots here is 35 mph...so it's always a risk...
..lighter roller weights..4.5-4.7gr....a 1500 main torque spring and +50% fly clutch springs will help....some....
..keep your tire air pressures up, your oil changed often, and maintain proper valve clearances...
..free-flow air filter, less restrictive exhaust and up-sizing the main jet in your carburetor will also help ...some...
..you can install a larger carburetor, and that will help...some....
..i'm still at the mercy of the big hills and stiff headwinds, even with the things mentioned above, except for the exhaust and the 1500 spring, i've done them all...it's just the nature of the lil 50 4t beast...
