Hello, I just purchased my first 4-stroke and after 2 rides I love it. It seems to be running great but I have a couple of questions. 1) Anybody in the NC or surrounding areas figured changed the stock jetting on the bike. My seems to run fine but it being my first 4 stroke I don't have any experience to go on. 2) I see all these topics on what type of fuel to use. The dealer I purchased the bike from suggested race fuel. (which I have no problem running) His reasoning is to make it run cooler. However, I was reading some info on pipes and the FMF literature specifically stated to run 93 octane in a 4-stroke with their pipe as for that's what it is designed for. Then the first thing a respected friend (Billy Liles) informed me to do is to run only 93 octane in a 4-stroke. (Preferrably Amoco.) His reasoning was the opposite of the dealer, in the fact that he indicated that the 4-strokes were designed to run hotter so you get better performance out of 93 octane. In my two rides, pump gas seems to do the trick. I would just like any opinions anybody that has experimented with both on an 01 or 02 bike. I'm hoping to get enough material to help make an educated guess without having to "reinvent the wheel" so to speak. Thanks.
