[QUOTE="Jasle, post: 791236, member: 26675"] [b]Few things you can do[/b] Well I'd second the vote for the Cobra PW3 Check [url]www.cobramotorcycle.com[/url] to see them. But for your PW50 the QT50 ring and pinion is a HUGE difference. it takes you from 4.9:1 to 5.7:1 gearing. I go about 230lbs and I can tell big time the differenct. Also you can deck the cylinder taking about .030 of material out to bump the compression up. Makes a huge difference. If you race stock classes don't do this! But if you just want more power for plasting around you can do it. Also a 60cc kit is availible. as well as a FMF pipe. Remove the oil injector setup and run premix. Take the stock main 70 jet out and use a 67.5 or 65. Stock the bike is way too rich. Also you can either shorten your stock clutch springs by one or two coils or get aftermarket springs. They make the clutch engage later so it is closer to the powerband when it hits. The springs are under $20 and the pinion gear is under $60 usually on that popular E lectronic Bay site. [/QUOTE]
