after screwing with these stupid toys since 2005, lots of tuning, testing, making parts and building engines for other people... building dozens of different set ups on almost every make/model
the lesson i've learned is that there is a certain 'sweet spot' for tuning, where the bike is really happy, fun and rideable, and going beyond that you start to go off a cliff for reliability, rideability and cost/maintenance.
yea, sure, of course you can do it, and its still fun and i still build gonzo shit every now and then, but if you want to spend your time wrenching and not riding, there are recipes that just work well together, and stuff that doesn't.
my hat is off to the people that build gonzo shit, do it so well that it blasts, and have the time and dedication to keep it running. There are a few guys in the community that have achieved that master blaster status, the rest of us just have garages full of blown up shit.
