CBR 600rr Engine On a 400ex? Any Info?

[minimac21234]

I tried searching around a little and couldnt find anyone thats done or attempted this. Anyone with any input or pics or whatnot? Im buying an 05 600rr motor and goin to try and fab up something on the 400ex with a few friends of mine.

Can't help on the conversion but I'd love to see a step by a step, with pics of the journey to super quad.

There are a couple of quads here that run road bike motors, all with 1000's in them.

450r with CBR1000
450r with BRM1000
ltr450 with gsxr1000

Apparently there is a suzuki ltr450 in the build that will have a hybusa motor with turbo and they are looking for about 250hp.

They are all pretty chopped up and not much good for anything other than hill climbs on gravel.

If you want to have a look just google " ian ffitch" there is heaps of stuff.

well i figure with the 600rr motor...when i get it hopefully within the next few days, i can do some measurements. The 1000's are ENORMOUS motors. The 600 isnt huge but it isnt going to be exactly an easy swap. I figure if i can keep everything the way it looks now minus the frame, ill be happy, or with minimal adjustments to the plastics. I want it to be stock looking plastics, no adjustments or minor asjustments to the tank, and hopefully running fairly quick. I want it to be as torque like as i can get it compared to the 400ex's but beat 450r's in the stretch. It will take some time so hopefully i can rig up some plans and keep you guys updated.

I've seen a DS650 with a hayabusa engine in it. It was a turbo too.

The engine looked like it was MADE for the quad, since the DS is so big it got away with it pretty damn good. Other than the extended swingarm, you can pretty much ride it anywhere you want. The only difference was the swinger and the engine.

But heres a video of an lt500 with a hayabusa engine in it.
