500cc alcohol two stroke go-kart
I was going through some old stuff (old to me!), and found this....I thought some of you gear heads might be interested..
500cc (yz490) heavily ported using a mikuni 44mm carb converted to alcohol. The needle in the carb was made from 1/8" stainless welding rod and turned on a lathe 1/4" at a time. the frame is 4130 chromoly with 7075 aluminum structural support around engine. There is a spring loaded wheelie bar in the rear to control wheelies at speeds below where the front wing starts to work (65 mph or so).
on an 1/8th mile, we were doing 9 second lap times, and on the quarter mile we were doing 11 second lap times, hitting about 115 on the straights...
I miss that thing!!!
