400ex Parts

I am also adding a step of 2 Hot Cam. I have a new cam chain, do I replace the sprocket? I am also replacing the seals. Any idea of the size of jet? I have a rev box, go get a hose, consumption. Any other top end I replace it?

the kit should have all the stuff inside to finish the job, but you may have to jet to allow for more fuel to pump into the head ....
I would like to communicate with people who make the kit 440 and ask them to throw specifications and recommendations, and then try to ...... first and then play with the stream of what works best for you .....

what pinion are you talking about this issue, the sprocket chain or sprocket drive ?????


If you ask on the sprocket chain, if worn, then yes, if an old bike that has lots of time on it, then yes .......
