400EX ?

I just bought a 2001 400EX. A friend of mine said there was a plate or something that I could take off of it to open it up for more power and speed. Is this true? If so what is it?

He may be talking about the air box lid. If so, I don't recommend it. If you want more power, get a K&N, a jet kit, and a Big Gun slip-on. That'll impress you I'm sure...

Re: 400EX ?

there is supposed to be a way to disconect the rev limiter, thats probably what you are thinking of( I ride with a guy that has one ,but I'm not that up on the thing) I do know that if you pipe it, it makes a big dif. there is a ton of things you can do to it to make it fast , NOW MUCH $$$$ DO YOU WANT TO SPEND???

Pipe, K&N filter, and jet it! Thats all you need, Don't start messing with the rev limiter, you will be sorry for that. just make those changes and you will have plenty of power! Good Luck! Thats a nice machine.
