Just something I noticed in one of the eariler post you mentiond that the bike was sitting for a while. If the lines were never purged methonal has a bad habit of gumming up lines, jets, etc. and corroding aluminum. So before you run it i would go through all the fuel lines, petcock, carbs etc... That's a nice motor that I wouldn't want to lean out.
Now I have never run meth on a banshee, but in sprint cars i have and I always found marvel mystery oil works the best on keeping the lines clean. :thumbsup:
