500 progress pics!
« on: July 11, 2010, 09:38:54 AM »
Heres my 2009 KX250F bike, the motor was a tight fit but I got her to work with the factory Y piece in the head stem with some modifying of course. Man what a giant motor this thing is, now I am on to making some motor mounts for it and hopefully the motor will still come out after there welded in :?. I already got the airbox ready to go so all thats left is the rads and some mounts for the motor and pipe not to much longer I dont think. I traded the 09 250f motor that was in the bike for a 97kx500 motor that mcr suspension had (a local race shop) . They rebuilt the hole thing matched the cases ported it out v-force3, brand new everything from the crank and piston even the whole tranny so it should be a really nice unit. I will post more pics when its all done!

Looks like your off to a great start! What did you use for frame rails? They look like they're still one piece?

I used j fabs rails but I had to use them backwards cause the 250f frame was a lot diff. But it turned out looking perfect.

Very cool. thank you for posting your build pictures. I know it's easy to forget to take pictures as you go but it sure is a huge favor to the rest of us. what kind of amperage did you find yourself welding at if you don't mind.

Welding looks excellent, admire you taking on the 250 frame. They all say it's a big job compared to the 450.

I had a friend do the welding he has a syncrowave 350 I think.  he put down one main weld everywere and then double lapped them as well, I will take better pics of just the cradle when I take the motor back out for the motor mounts It looks pretty factory, And the 250 frame is WAY smaller then the 450, It took me a long time to get the motor in the position I wanted it in it has about .020" from the front of the motor to the head stem I had to take out little by little to get it perfect.
