What Scott said.
Alan also asked me about the throttle body bit. This is what I sent him:
To open up bolt on air filter possibilities as well as allowing for better air flow into the throttle body. I don't know if it's actually beneficial to top speed or anything. It seems that quite a few people have already done it though. I figured listing the most common modifications would be good, and turning the throttle body around seems to be up there with a pipe etc.
Just trying to make it appealing to people that have Groms to show up and race with minimal work to their bikes.
