Im gettin about 6hp outta that awesome Honda cx35...40mph is pretty fast. Ported and polished intake and exhaust, Juice box intake, 15mm Walbro carb, High flow air cleaner. Straight pipe sounds cool like a Harley it chugga chuggs till it revs up to speed. Brake is suicide handle, stops good looks cool, but a little gettin usedto. I've git it reduced right now, just to make a sale... 600, seller arrange for pickup. The tranny is an X-2 pocketbike, I've had good reliability out of them, easy to service too.
