YES YES YES. Methanol "not 'alky'" is TOTALLY worth it, especially for a drag bike.
People make purging out to be a way bigger deal than it really is.
1) Either drain the existing methanol out of your tank when you're finished riding, put in a little purge gas and run the bike.
2) Get a small bottle (like a Lucas oil stabilizer bottle or similar with a nozzle on the end), make a tee out of fuel line, unhook your fuel lines and hook up the tee, bottle feed and run the bike.
It's really pretty simple, takes about 5mins.
The gains from going to meth from race gas are awesome. You won't be sorry you did.
There IS a learning curve on the tuning though, that's the most time consuming part is getting it dialed in, but when you do you will have a grin.
