I just purchased an 06 450r. I an a 250r guy and am not familiar with the factory jetting on these bikes. I believe it is stock, with an aftermarket silencer. The jetting is way off. The way the bike looks, it looks like it used to be raced, and they threw all the stock stuff back on just to sell it not caring one but if it ran right. I need to know if anyone knows what the entire jetting setup would be fur a stock bike with aftermarket silencer just so I have a starting point.

42 pilot. 122 main

You might as well go ahead and see what needle you have and get a 162 or 165 main & an NCVQ needle in there... stock pilot should be just fine
