depend on the money you have to spend > new carbs are much$$$$if it where me I would use stock carb start with a kehin 42 pilot, 170 main ,raise needle one notch on carb 4th from top of needle, and mixture screw 3 turns out that will put you in the ballpark, unless you have the money then go with is it the fcr carb people say the performance gain is worth the cash I think it is about $400, but I may be wrong, as opposed to $ 30 in jets with the stock carb, the fcr is better if money is not a issue hope this helps.
