I want to try a 22 tooth gear, 23 is to steep at the moment as others have said. Canít seem to find a US store with one in stock for a 2007 Stella. I donít need an entire clutch assembly. Itís not a Cosa setup.
I think you'll be happier with the 22, for sure. You're gonna be pissed at yourself if you ultimately wind up back on the 21 for more speed off the line, though
1-3 are good for me, I didnít like the 21, 1st was to short. Replacing my Sito+ with a PM tuning chamber may help with the 23 teeth. Dyno charts Iíve seen says itís better than the Sito around 55mph.
Box exhaust are primarily kingís of torque. If you install a chambered pipe on it, such as a PM Tuning, I foresee it making 4th gear with a 23T clutch even worse...1st through 3rd gear will probably still be pretty fun though...but it will most likely fall flat in its face in fourth. Gearing can be really tricky in our scooters. Having a 1st gear thatís too short can take the fun out of accelerating into the 2nd gear. I really think a 22T will be a great match with your cylinder and current exhaust. It should go great on the flat roads and mild hills. The real litmus test will be how well it pulls up mountain grades (if you live in the hilly part of the country).
