I hate the way Yoshi's sound. Too damn raspy unless they have improved recently. I'll check out some videos tonight when I get a chance..
I commute with the bike so heat gets to be an issue. That's why I'm looking for CF. Plus I think it'll just go with the bike much better since I picked up a black one this time.
Not sure if I really need a full system since I don't plan on getting a PC for a while..again, I commute and like the gas mileage I get out of it for now..
Patrick or Amber
Congrats on getting a bike again.... finially 
For teh screen - I perfer the Zero Gravity Corsa style - functions like a double bubble but not as ugly as one. But if you want I have a Lochart Phillips clear double bubble, never used (except to mark and drill hole on a set race bodywork) I'd sell really cheap.
For the exhaust - FTW - titanium... everyones' got Carbon now days...
Thanks Jason.
I'm looking for a "smoke" or "blacked out" windscreen.
Also, I checked on their website and it seems as if their pricing is a bit higher than many other places..do they give better pricing for forum members?
