durden, maybe try just the 13T sproket first? If you buy a pipe you will most likely have to rejet. There is no problem with reliability when done right. When you increase the air flow in the exhaust you have to increase the air flow in the intake (air filter with air box removed) with the increased air flow you need to match the fuel mixture. have it done buy a guy that does it all day and he will get it done right the first time with no reliability issues.

je2000 you have to decide what you really want. Yes you can change the front sproket from a 14T to a 15T and the rear should be a 45 I think and they should have a larger size available; however your lower end will suck. The stock gearing is not that bad? Maybe try the 15T front sproket and see where that takes you as high speed on this bike is not that stable you may not want to go to fast?
