Anyone take a twin cooled 103 and do complete exhaust, A/C and tune along with a set of heads? What kind of numbers did you get? I currently have Jackpot 2-1-2, 4" dyno tuned mufflers, pro billet A/C and PV2... What horsepower gains should I expect by adding Fuel Moto heads? I could call Fuel Moto of course...

 

To get the best answer I suggest you call them.

 

You'd be better off by going with cams first, with stock heads. Cams are the bottle neck after stage one. Or add the cams along with the fuel moto heads. The fuel moto heads by themselves with the stock cams won't be the best money spent. The velocity of air will possibly slow down and you may lose performance. Hence the need to add cams with the heads. The stock cams simply can't support the flow potential of fuel moto heads.

 

Thanks Dude...
