a 400ex engine has been done in a 300ex chassis, i dont know who did it but it can be done,


you could also consider a big bore kit for a 350 x engine,


as for the 450r motor, im really not sure, im sure it could be done, but thats alot of engine for a 300ex frame to handle,

HOw much work needs to be done for the 400ex converstion??
Idk my 300ex frame has been through hell and its still strong....
I broke a front shock before the frame bent...Idk i jsut like the way a 300ex rides but i want more power out of it..Something to at least keep up to a 400ex.....Thanks for the info

well heres an idea


why dont you just build your 300 motor?

a well built 330 will run with a stock 400

and well built 390 will smoke a stock 400

Yeah i thought about it..
But with the money it takes i might as well go with a hybrid...
I want something to run with the big dogs and im not gonna get it from a 300...
No matter what i do....
SO a 400 with some mods should be about right..I jsut dont have the money for a 450 right now and and i have yet to decide if i should by the 300..
Its my friends and i changed the oil and whatnot for him and iv been riding it for a while....But i jsut wanted some ideas on what i should do and i think i might just get the z400 iv been lookin at...It has a bent frame but i have some people that can make it strieghter and ridable but it will never be streight....
Thanks for the info and if i make a sick hybrid ill post it up here....

Don't bother with that. PM me and I will give you the number of a guy who can make a 350X conversion that will blow the doors off CRF's YZ's 250R's and probly most of the production quads..

if you don't believe me, find a video of the 2003 High Point 250 Pro-Am holeshot when his 350X based quad pulled the holeshot by a few quad lengths..

He could do the same w/ a 300EX motor, but the 350X would be your best bet..

That may have been Gil Attix on that 350x powered quad. I know he had a few back then. He was an east coast rider so they may have video of it.
