Picking up my new '08 this afternoon and will be moving several parts over from my '06 (stabilizer, bars, handguards, etc, etc.) but I wanted to get some thoughts from the forum on a couple ideas. Exhaust: It seems pretty evident that the '08 exhaust sucks. Right now I have a full Leo Vince X-3 system on my '06 that I could use, or I have the stock '06 exhaust that I could use. I could even keep both and throw the '08 stock exhaust on the '06 and sell it, right? Recommendations? Carburetor: The carb on my '06 has had the Zipty Racing carb mod done to it...should I throw that on the '08 or did Yamaha tweak the '07 and '08 carbs enough that the Zipty mod is not necessary? Any other tips or recommendations?
