CRF250R Gen 4 CR5 conversion
CRF250R Gen 4 CR5 conversion
Hey all,
Figured I should post up the build pics for those who are interested, I have been reading up big for the last year on both forums and the knowledge available has been invaluable and gave me confidence in doing my own. I live in Australia so importing one becomes pretty expensive.
For this conversion I picked up a rolling CRF250R 2007 chassis and I am using my 94' CR500 motor. I ordered Jercs conversion kit which is not only cost effective but accurate for fittment, easy to do, and the instructions and support from him is good
The hardest thing for me was the actual cutting the frame up, it just didnt feel right but it had to be done and the results have changed my thoughts on that, now pass me that saw !!
pics or it didnt happen right.
Old V new.
This jig is a must for saving time. now who did i get that from I wonder?
CR125 spacers
bit of a clean up, motor in.
Headstay brackets lined up nicely.
Radiator outlet ready to weld
ready for my welder to finish the brackets.
MRE decomp head.
Hinson basket and oem fibres. Magura hyd clutch.
Parts on order:
OEM reeds
CR250 airboot and cage
CR250 brake pedal
CR5 kicker
head stem bearings.
new plastics
Clarke 3G tank
CRF'X' model tank petcock.
bolts/screws, collets, rubbers for tank etc.
Once all this is done it is the shakedown ride.
Next on the list will be:
Suspension reset for my style and weight.
Sticker kit yet to be designed
Later on will be a full engine rebuild.
Dig ign
Lighting stator/kit
D inj if or when it is proven and available.
Maybe a GMX tank (bling)
Recommend that a good experienced alloy TIG welder is sourced
Biggest issue is the unpredictable shipping time for parts.
Would I do another one, yes

Np. I am running the 2000-2001 GEN 2 kicker. I like the GEN 3 (2002 and up) kicker alot more but find the bushings in it wear out quickly and it rattles like crazy. Also believe with the gen 3 kicker if you run a FMF pipe it will interfere with the kicker about mid-way down the shaft (Atleast it did for me). You can try to avoid this by "clocking" the spline on the the kicker mechanism or just run a PC pipe which should have a bit more clearance.
CR250 kicker shares the same spline as the CR500 and fits the frame better![/quote]
and breaks easier busted 2 brand new 250 kickers within a month of fitting them us the cr500 kicker its designed to start a cr500

I need to prune those bushes in the background.
Its running after a few electical issues. My fault
How do you get youtube to work?
Heading out thursday for the shakedown, all goes well the Husky will stay in the trailer for the long weekend, had a few issues and moments of how the hell can I make this work, having a beer and thinking about it worked many times. Beer is good
I will miss the lounge chair seat ride of the steel frame.
Looking at the old frame then I look at this, those who have done it know

Oppertunity arose to take it to a friends property yesterday, not many good photos as it was raining too much to have my good DSLR out.
I tell you what it is definately like a scalpel as others have mentioned, it felt light and turns brilliantly, ran 14/45 gearing and it was much more manageable in the tight single trails out of the turns, it has to be one of the best bikes I have riden. Didnt notice any vibrations but I will find out on the longer trails.
Not one issue with the build results, the motor ran sweet with new reeds and Roosti's decomp head and could ride a gear higher even in the tight stuff. it was jumped a few times, we hit the stutters fairly quick and generally tested over 3+ hours.
Front tyre just barely touches the pipe under full fork compression. Should be fine.
Waiting on some stickers and a few tasty bits to finish it off, what a ride from the building phase to the testing and having no issues, if it wasnt for this website and all the freely available info i would never have attempted my own build.
Cheers all
If your thinking about converting do it, so much better than the steel frame version.
