I would not run alky if you are doing much if any duning.
If you are building a drag bike, there is no other way...run the alcohol. Easier to tune and jet. Purging is the only real thing you have to do besides keep a little closer eye on your plugs. Alky is a little more sensitive to temp and humidity changes, but unlike gas, you can run a alky so rich the temp and humidity changes won't matter. The power difference is substantial. If you change nothing else but the things required to run alky optimally, it will put a smile on your face. And, even though you burn twice as much fuel it is still way cheaper. I paid 12.50 to fill up a f gallon jug of alky this last weekend!
