A lot of the stuff vendors are selling up there is crap. I'd rather buy stuff for my bike from a shop that will be there in two weeks. There is some good stuff here and there, but that is generally hard to come by. The key is to know what you're buying. The other thing is dyno runs. There are a lot of people up there with trailer dynos offering dyno tuning. Most of them don't really know what they are doing, and some even burn up motors once in a while. Just something to keep in mind. If you are into bikes, check out another forum I'm on:
