Ok,
I just got an 01 400ex and I love it. It came with a white bros e series slip on and thats it. Well since then I've added a k&n filter and ground down the header welds and it ran like ****. I could be climing a hill and it studder and bog big time. So I took of the air box lid and it ran good for a while. But now it studdering again and can't pull up a wheelie in 3rd when I could before.
Anyhow I took out the plug and its white.
I know this means it is lean but what all would I have to change? Just the main?
What size jet should I go up to it has stock jetting now a 148 main.
Later Ryan H.
