I was doing some basic maintenace on my new purchase when I noticed a "dial" of some sort behind the gas tank. It reads -2, -1, 0, +1, +2, and +3. What is this thing? Thanks guys
Thanks freeride! Its setup for race gas and has the stock "snopro mod" heads on it. The dial is set at 0 so i think this is probably good?!? Thanks for your answer i appreciate it a lot!
