HI, you can get a straight through exhaust and open up the airbox. new jets can be bought from kedo in germany. you could go for cr carbs and k&n's but it would be cheaper to just bung a 600 engine in. its a straight swap for either twinshock to twinshock or mono to mono shock. Crs carbs are about £450? the choice is yours.........
