I am looking to do some mods to my 400 I don't think im going to go with a 440 big bore kit yet but id like to have a nice cam in it. The bike i got has a whitebrothers pipe on it not sure on how good it is, but i have seen it on a lot of different 400s out there so it must not be to bad or just really cheap? Anyways back to my question i wouldn't mind having some head work done and maybe porting and polishing. Where should i go to have this done what kind of cam should i look for? Who is good with working on the 400ex's i don't want someone who doesn't know what they are doing touchen my head.

 

do you have the number for mad racing?
