Hey Guys, long time Kawaie guy here, had alot of Kawasaki products in my life including Quads, Dirt Bikes, Ninja, and now a brand new 09 VN900 Special Edition. I was in the market for a cruiser and found a left over special edition for $5895!! When I bought it, it only had 0.5 miles on it! I think it was a pretty good deal. Anycase, I did what alot of you guys do with the exhaust. I removed the baffle plates, and drilled 8, 1/2" holes in the baffles and drilled out the center plug in the center of the baffle to get more sound. The sound is pretty good, not really deep enough, but not that bad. But I am getting some popping on decell and a small backfire here and there. Anyone know a remedy to fix it, or is it just what these bikes do? Also, what is the best bang for the buck Mod on these bikes for HP/TQ increase? Plug and play fuel controller? Pipes? Big air kit?
