Gen 4 crf250r-cr500 conversion getting started
Gen 4 crf250r-cr500 conversion getting started
Hi everyone, just gettin' started with my conversion, it's been a little slow to start with but I'm slowly getting the parts together. Thanks to Bean and Paul Stoffers for the rails and mounts
The doner, 1991 cr500 picked it up from the local trading post.
The 2006 crf250r, picked this up on Gumtree locally, it was a roller with a buggered engine, have gotten back $700 and still have a couple of good bits left that can be sold to help fund the project.
Chipping away at it last weekend,
The Donk
chop chop
A little way off but getting there, waiting on some parts to progress further. Thanks to everyone that has posted their builds on the site as it has made it a lot easier for me to do the conversion.

More progress this weekend, sat the engine in and starting to work out the locations and clearancing of the radiators, exhaust and airbox boot.
The mounts, it seemed a little off with out the washer so I put one in to make the rails sit better
I made a template out of 3mm mdf and was able to test fit the boot/airbox before using some 5mm aluminium sheet for the final product.
The template (free to good home if it will help with your crf250airbox/2000 mdl cr250 boot adaption)
I will have a shot of the finished adaptor next time, I was short of time and wanted to check the boot clearances
Kick starter and exhaust clearance was good
Finally I have a crf450 airbox adaptor that was no good for my conversion, If you are looking for one for your 450 style conversion drop me a line and make me an offer, it is a Bean ind made adaptor that i purchased earlier this year with my rails, I was unaware that wouldn't work with my crf250.

Hi everyone,
Finally getting things back on track after moving ect, time seems to slip away if you're not carefull,
A couple of new pic's to get things rolling again. frame is all welded now.
Went balls deep and bought a set of the chinese rads and for the money can't really complain! they where a fair bit larger than the OEM's but feel they came up fine with good pipe clearance now.
The coil seemed to fit well enough in here
I had to take the crank back to the chap that fitted the new rod seems it isn't quite right and was a touch tight when the casing were torqued up so this put a stop to the assy until next week
Going the single coolant outlet way, have access to a good machinist and machining up a new out let was easy according to him and should flow pretty well as it is bigger than one of the old outlets.

chipping away doin' some more to the bike.
As i said Bob the fcuked up tank effort, looked easy on your sticky
The single coolant set up I ran with
Exhaust mount, I saw a few styles but this was simple and worked fine.
Been doing all the crap but essential jobs like greasing the linkage bearings and the like, but finally getting to the good stuff.

Hey mate looks good you could you could always run the second out let out of the head just like the stock setup you just need to mod the radiator and run a cross over hose.

Hi Gregrobo,
I did want to run the two outlet with the elbows but was having trouble getting the clearance under the tank and didn't want to weld fittings in to the head, this is why i wanted to keep the head std so that when i get the cash for the Acerbis tank i can go back to the std setup if I have problems.
Hows the WB resto going?? still doin' it??

Hi all,
Just about done but waiting on a low profile plug to finish things off and couldn't wait to see how it would look. here a few picks of it almost finshed.
I will post a ride report when I receive the last parts to get it running.
Thanks to Paz for letting me spread my bike out at his work shop for 12 monthes while i got my shit together and Matt for welding up the frame.
I look forward to catching up with any W.A hoons for a ride and a few beers.
Cheers Max

Hi Redbull500,
I got mine from the normal auction site most of us use. I just searched "silicone hose 90 deg elbow" and got the 19mm one with 150mm long legs as the fab'ed elbow in the head was made to suit the CRF250 left radiator top port (I think std 500 is 16mm), the rest of my hose is a blue CRF250R kit as all my prefitting was done with the original hoses just cut to different lengths for the barrel and bottom rad hose. I did this because I didnt want to purchase a CR500 hose kit for some hoses and a CRF250 kit for the rest.
hope this helps??
