KX250AF build

[stevea100m]

So I spent the better part of a day and a half workin on the adapter plate for the airbox to put the cr250 air boot on and once I got done with it and got it mounted up i just have to get a reed space. The only thing im tryin to figure out is weather I want to put it in between the cylinder and reeds or the intake and the reeds. I also got a set of oversized cr250 radiators for the bike and now have to move the lower water spicket on the right radiator out about an inch or so. I have all the plastic on the way for it so it should look like a bike by the end of the week.

SO i got a little work done this weekend. I worked on gettin the radiator brackets made for the oversized 02 CR250 radiators. I also figured out how im going to run the radiator hoses for the bike. I have to have the right side lower radiator spicket moved outward as it hits the cylinder. I got my new plastic in so i just had to put it on to see how it looks. Gonna get the now rod and piston ordered friday. Figure if I'm building a new bike might as well have a new motor

So i changed how most have mounted the radiators. I decided to make an adapter bracket to make them fit easier. I havent finished them yet as i have to weld two spacers on each bracket and once i get that all done then im going to trim the excess material away so they dont catch anything

So I finally got my over sized tank I was hopin to get. Its an IMS 2.8 gallon tank. It has a lot more clearance for the spark plug than the stock tank. Im taking it all apart this weekend to take it to the welder. I probably wont finish it till the middle of may as Im headed to Vegas for the supercross finale.

Gettin some real work done today! I bent up a set of frame rails and started fitting them to the frame so far Ive got one done and am going to start doin the other side after a short break

I really like the radiator adaptor plate idea! I never thought about that! I just cut the lower mounts out of my 500SF project and welded them forward slightly. It would have been a ton easier and nicer looking to make the bracket. Oh well Ill remember it next time.

Do yo still have the steel roller? If you do, are you willing to sell it as a whole roller?, and how much$?

Where do I begin, its been a while since I posted an update on the bike. Since my last update I completely changed which radiators I used, I decided to go with radiators off of a 2002 kx250 and just have the tanks modified to clear the frame. obviously the radiators have the to crossover pipes on them so i had to figure out what to do there. So I got on the summit racing website and found weld on threaded bungs and some -an fittings that thread on and come straight out of the radiator and turn to a 90 degree angle and they work really well. I also have since the last update made the motor mounts and had the whole frame welded by a very reputable welder that has welded some AF conversions before. THe bike is fully assembled and I am just waiting on a petcock so I can hear this thing run. I still need to heat the bottom of the tank to clear the shorty spark plug that is in the motor. One thing I had to also do was use the hammer head designs brake clevis kit as the pin was missing for the pedal and i couldnt get the spring hooked to the pedal as the motor was in the way. I highly recommended this as you can also adjust the pedal tension. Here are some pics of the stuff that I have done if anybody wants more specific pics let me know

bit late i guess but i used kx125 rads fit straight on no mods required ,again bit late but if you need any info check out my post jan de groot etc

I had seen your when I was looking at moding a set of radiators but this was the easiest as I already had the radiators and made the block off plates myself, so just cost effective on my side. But if I smash one I may try that next

Looking good!

I'm trying to be meticulous about a lot of it as i want this thing to make jaws drop when I'm at the track

like this one?

[stevea100m]

IT LIVES!!!!!! I had it running last night on the stand and all I can say is I cant wait to ride this thing. I just got some tall stiff seat foam installed today as well, and what a difference it makes for a taller rider.

No pictures... it never happened!

Im hoping to have a video up this weekend
