700cc 400EX????
i'm wondering if it would be possible to put a 700cc or 800cc engine in a 400EX. i'm thinking a 4 stroke engine, not jus for drag racing, i'd use it as an all around quad. how much would a motor like this cost? what other modifications would i need in order to make this work? would puttin and like this in the quad even be worth it? or could i spend the same money and get a raptor and a bunch of mods? thanx

If you have good fabrication skill, it wouldn't be much of a problem. I would prefer a twin, over a 4 cylinder, mainly because of weight. I am going to build a 800cc or bigger next year. I think it's better when you build your own, than buy one! Look at it this way, no one else will have one like your's, when it's finished![img]i/expressions/face-icon-small-tongue.gif[/img]

Yeah the 400EX frame wouldn't be my first choice. Could be done tho. I wonder if one of the old 650-750 twins could be made to fit? There were a ton of those around in the late 70's early 80's. Theyre air cooled so you wouldnt need to worry about a radiator. Reliable engines to. I had a old Yamaha 650 that went 65k without a rebuild. Not bad for a 20 year old air cooled twin. Of course the power wouldnt be anywhere near as big as a newer water cooled motor but it'd be a big jump from the 400ex engine.
You would have to come up with engine mounts and an exhaust. Beyond that it's mainly a matter of fitting the whole beast in there....
I've never done this tho... just speculation.
