What kind of mileage are you guys getting out of your 38mm Airstyker? I am currently running a 275 Duncan PC2000 cylinder, CR250 boot, CR250 Boysen Rad Valve, 1/2" reed spacer and stock airbox boot with an open airbox (EHS Racing cover) and 4 gallon IMS tank. I have run two trips on this setup and I able to go about 40 miles on 4 gallons of gas at a moderate pace. Is this reasonable for this size carb? I was running a ESR 310 (non-pv) cylinder with UPP boot, V-Force 2 reeds and a 35mm Keihin (non-airstryker) and could go the same distance and use only a gallon and half of fuel. This was a great setup and I am thinking of switching back to that, with the exception of the PC2000 cylinder, as I need to be able to cover more miles when I trail ride and race and I am now using VP 110 and I really don't want to spend $50 for one single ride. Yes, I am cheap :highly_amused:

If i remember right, my buddy was doing about 25 miles per tank(stock tank i believe 2.4?) with VF3 reeds, 38 a/s, trx9 cm pipe, and airbox elim kit. mixed 40:1 on 93 pump gas. I dont really notice much of a difference on my wifes bike with a 34pj compared to my bike with a 40.5. And i know she isnt riding harder than me! haha.
