did a little write up of what's involved with that gila kit. haven't actually had a chance to ride the bike though. there were some shimming issues when the engine got put back together that caused the rear wheel to be engaged to the pedals at all the time. it was my cousins bike and he hasn't had the time to dig back into it yet. that being said, with an mk3 pipe and a sha15 it sounded like a ripper when we started it up.
