i am going to be ruinnin a +6 and ive got my bike drag ported, i dont know how much hp it will be pushing but we did try them on cp5899's bike with a +8 on there and he was either keeping up or beating 25,000 and a 27,000 $ bikes, one was like a 586 and the other was supposed to be bigger, we have video's of them racing.. anyway.. the +8 on his bike wasnt enough for him but it also depends on how much traction your getting on his bike he runs 12 paddle haulers, on mine i will be getting 10 paddle extremes, also your gearing comes into play for this also. on your suspension im going to be running the stock shock in the rear and its going to be set to get the most bite i can get. hope this helps you out,
Later B
