No one will rip on you man. The best part of all these builds is you learn a little something along the way and when your done, the bike is YOURS you know!

Thanks man, thats what its all about

That is very true.

79 views and this is all i get ? it's just as much your piece of shit as mine, only its in my garage. i copied all you hoons

I didn't read everything you wrote over there. Just listen to the advice you get, don't get in a hurry, and don't put lawnchair bends in your craddle and you'll be good!

I will have to wait to see your build because I'm not joining that stupid site over there, so you better make it quick.

I tried that. NO WORKIE!

Thanks for the pictures though, but you guys building CRF250R bikes are starting to make me wonder if I should of bought one instead of my gen 3 CR250R.

It's looking great so far, keep it going.

CR500R7 i can't say from experience about the cr250, from what i have read and know of from people i race with they like them.
the conversions are also popular.

I have no doubt that I'm going to enjoy My Gen 3 CR250 when it is converted to a 500.

I think it is "the kid in the candy store" syndrome.
Not happy with one conversion, must have one of every conversion.
What is funny though is that I really hate the CRF250 ( it looks like SH!T ) but as soon as you stuff a CR500 engine into it, it becomes a FANTASTIC looking Motocross bike.
It looks totally different, don't know why, just me I guess.

Pic's of the new mounts, i had to have my lowers made as left and right sides because of the radius of the new rails. the top mounts are siamesed.

those bottom mounts look beefy...i like'm

Looking good dog!

Thanks Hoons, just tryin to do my best

Looks good

OK today i took my frame, subframe and exhaust to the shop for weldng. Everything was setup and ready to go,spent 4-5 hours welding all of it including a repair to the fatty pipe that had vibration cracks in it. Its been awhile since i welded aluminum, the frame looks great and im happy with it.




Here's pic of the exhaust, it's bolted up with minumun tension on it. 8-)





The rear mount in this pic utilizes the fender mounting hole with a fully threaded collar that can be bolted to from both sides

up next is measure for the headstay and get the print to the machinist, while he's doing that i will start building the moter.

Getting to this point in the build has given me great pleasure and relief. Thanks to this website and the cr500riders site i was able to accomplish this build. I would have never even thought about it if i didn't find these two great websites and the info posted by some very talented hoons.

OK, THIS past weekend i put all the parts together. Sunday afternoon right before easter dinner i fired her up, went for a ride around the yard and ripped up some grass and dirt. This thing pulls the front wheel easier than my old crf 450 and sticks on the grass in turns great
( throttle control). heres some pics




heres some pics of the cdi mounted to the side of the frame with the rectifier and cap mounted on the inside of the works connection radiator guard. this is a temp position as the cdi is to big to fit behind the # plate, i plan to get a 2000-2001 iginition system so it will be a clean mount.


heres some pics of my headstay made from the stock crf250 stays, they bolt up without any side tension on the stays and the offset is perfect.




pics of the finished bike,


Here a quick review of parts i used to build my conversion:
2005 crf 250 frame, swingarm and subframe
1995 engine cases and clutch case
2001 cylinder
90 mm wiseco piston with new rings coated by swaintech
1992 close ratio transmission
39.5 mm PWK Airstriker carb
2000 cr 250 cdi, flywheel and stator
1998 cr 250 airboot and backing plate
1998 cr 250 rear brake pedal
modded right radiator to keep the stock cr500 cooling system
14/50 sprockets for now, seems to pull quick enough for me at this ratio
FMF Fatty with a new pro circuit 304 silencer, i have the new works pipe i just haven't got it to the shop to mod the rear mount yet
All new bearings, gaskets, seals and hardware. crankshaft was also rebuilt with a ims rod kit.
Everything else is stock for either the crf 250 chassie or the stock cr500 running gear.

This bike is diffenitly going to be fun and challenging to get around a mx track, after the first start up and cool down it did fire up with a couple kicks, this 500 is new to me and my first one so until i get some seat time and read the plug for jetting it seems to run pretty dam good as is. Also i don't have a
headstay yet and won't be riding the bike anymore until i get one, waiting for the machinist, until then im going to the shop tomorrow to fab up the crf headstays to use until i get the one peice stay.

side note: without a headstay i didn't notice any bad vibes except at idle, quess i got one of the cranks thats smooth.

Thanks to everyone who has posted build info on the 2 sites to make it possible for other people to imagine their dream and build it.

Really very nice, a great job for sure.

Build looks great!!

good work man!!!!! cant wait to finish mine
