i want to put a xr650 motor in my 400ex frame is it possible or would it take alot of modifaications
or has anyone here tried this
thanks in advance

 

theres a guy on here that put that motor in a warrior frame... so it could be done... i dont know how difficult it would be but i dotn think itd be easy...

 

yeah, easier to do in a 400ex frame, but still a LOT of cut weld and fab. probabaly be better to go nuts with mods on a 400ex motor. you would also have to adapt a radiator, completely fab an oil tank. not an easy job

 

Not an easy conversion by far, many months and countless hours of cutting, welding, and fabricating things from scratch. I have a 400 EX also and another XR650 engine that will probably end up in the EX as well, but the conversion doesn't look like it's gonna be much easier than the warrior was.

 

I think it would be a lot easier to get a raptor or a ds650, but I guess there would be no fun in that.

 

XR650Warrior, Do you have any pics of your doing your xr 650 project? I would be very interested in seeing the builing of that monster! Thanks

 

Well I built the XR650 Warrior before Raptors and DS650's even existed because I was tired of waiting for the Mfg.'s to come up with a 'Big Block' 4-stroke, soon after everything started coming out, but it's nice to have a custom bike anyway and now I have plenty of competition, but I hold my own and run with the best of 'um with my 80's technology motor and just have a good time doing it.

 

Blasteridr, yea I've got a photo albulm full of the conversion, but have a hard time posting pics on my junk computer.

 

ive done it i used the 650r motor and a 250r radiator it looks factory the frame and swingarm are painted yellow the subframe and steering stem and all the little brackets are getting chromed and the motor is at thumper racing getting a 680 kit i cant wait to get it all done i will be in kermit texas on thanksgiving weekend

 

We might make Kermit on Thanksgiving wknd. as well,

maybe we'll have a ( liquid-cooled vs. air-cooled ) Honda 650 shoot-out
