i have a 660 roller my co worker wants to sell me for 200$ Complete with blown and rusted motor. I know i can make my money back selling the cases and tires alone. What i want to know is this roller a good candidate for my 10mil serval? I have never rode a 660 will it be a huge improvement over my stock suspension banshee frame? There is a guy on another forum who has done this conversion and is willing to fab me up motor mounts for 150$, He also says that the rator frame requires no modifications to your pipes he ran cpi's no problem. Any advice? I heard the 660s where wheelie monsters but i also heard you coud fab a banshee swingarm to fit it which is 2" longer and wider that a raptor stock swinger? I'm gonna get the bike reguardless because its worth more than 200 in parts... All posts welcome...
