JMAN, from the research I have done and from the guys here that have done it, you can run up to a 240 in the stock swingarm without changing anything but the tire/rim and rear fender. The rear runs slightly out of line but it is minimal and doesn't seem to cause any damage. You can check out CustomWorks or Breathless Performance or Eurocomponents for a lot of these products. I'm pretty sure all 3 are out of Florida. I have done business with Custom Works and they have been great. No experience with the others but there is a lot of info on the site.
Welcome BTW to the best site you are gonna find. Good luck with what you do, I plan on doing it this summer, as long as the wife doesn't see the stuff arrive. :diablo:
