Default Will a 500cc Two Stroke Engine fit in an 2011 GasGas Frame

I was considering a new project. I was thinking about looking for a GASGAS rolling chassis. Would a CR500 engine or KX500 engine fit in a 2010/2011 GasGas B Frame? I know the motor mounts would have to be moved, down tube may have to be cut, head on the 500 would have to be turned around for the head mount to clear the fuel tank. Has this ever been done?

I can see it now... "Why would anyone want to do this???" "What a useless bike that would be!!!" Whatever to that bro I'm with ya I love projects like this that involve some real fabrication challenges. I haven't seen anything like that so I hope you give it a go!

My buddy has a CR500, that motor in a GG chassis would be insane.... I love it! It's a larger motor so I'd imagine some changes would need to be made. Mounts etc..

I'm on the lets make this happen train!

First thing would be getting some measurements and specs for both and then deciding if its feasable and how much work would be involved. I'm guessing you don't want to modify the chasis too much as you'll be looking at retaining the gasser feel just with more grunt!

Default Just Guessing

My thought is a kx might be an easier swap
The original gasser frames were supposedly a lot like the kxs of the time
So maybe............
Anyway good luck and we'll all want a build up thread

Default Do it!

Have you seen Donny Emler's KTM/KX500? I think there's a article on it in MXA. They slid a Service Kawasaki KX 500 motor into SX 250 frame. It's a beast!
If you need any help, let me know .

The GasGas motor was stolen from a late 80's Honda motor. Could go either way. If you want a cheap gasgas rolling chassis, look for a 450 with a lunched motor. That chassis would have more room for the 500 mill. Find a nice one with low hours, U-rims, and the zinc plated frame.

I'm waaaay on board. What about using the KX500 mainframe & attaching the rear half of a Gasser to it. Shave the mounts for the KX shrouds off the frame, drop in the GG fuel cell...blah, blah, blah

Frame is the same on 450 and 2 stroke frames, just the mounts are different. So any bike is the same frame size anyway.
