if you think about it just buy a windage tray and put a one inch spacer under you carb. it is much cheaper and does about the same thing. The only thing that the airgap does is it cuts down on heat by keeping hot oil from under the carb and it helps itomize fuel a little better. another thing you could add is a heat sheild forthe carb too. Look at the cost. Option one 239.99 + shipping(250.00) option two windage tray 25.00 a one inch carb spacer 40.00 a carb heat shield 15.00 total 80.00 + shipping 90.00. just think half the price same performance= more money to spend elsewhere!!!!! that is great!!!
