400ex 416 426 440 motor

[400exto450mx]

Ok this is what i am looking for. I would like a 400ex motor with some motor work that runs good and does not smoke. It doesnt matter if i have to run race fuel or not. I have 5 weeks before my next race and i need a motor to get my quad back togeather. So just shoot me a message and let me know what you got and i will get back to you.

why don't you just rebuild yours? i have a 426 w/gasktes, piston and a new tc cam...heavy duty valve springs...and over-sized head studs....

dont have the money to spend a grand on parts and them 5 to 6 hundred on the build and i really dont have the know how to do it myself and i am planing on redoing one of them this winter with a curtis sparks 416 kit anyways.
