I've been scanning through the ATV aftermarket sites looking at upgrades that there are for the sp700.

I noticed on a few sites that there putting a 40mm carb on these bikes and finding a 4-5 hp gain.

Has anyone done this mod? and if so how much screwing around did it take to get the carb dialed in and how did you like the way it ran compared to the stock carb.

thanks.
