well i am starting my build on two hybrids. one for my son. one for my self. i am goingot put a cr500 in my yfz450 chassis. tierd of building 450 motors and having them blow up. so i am going back to fun and more reliable 2 strokes and to be different. i hope to have this built and running by the beging of flat track season in late november.

udated pics. got the motor in. got the intake plumbed and figured out. gonna use my fci intake, but had to have a angled shim. made the front and lower mounts. had the bushings the swing arm bolt goes through drilled out to fit he yfz swing arm bolt. have to mad a head stay mount and finish modding the pipe. so hope fully in the next week or so i can get the initial mock up done. then i can take it apart and finish weld everything. and put it back together and fire it up.

Ever considered the thought maybe you suck at or dont know how to rebuild a 4 stroke?

I know many fellow snowmobile mechanics who **** on four strokes only because they have no clue how to rebuild one correctly...too used to the easy 2 strokes....

Building a reliable 450 isnt rocket science...

On a better note.....i like the choice for a hybrid though....the cr500s were an awsome bike!

hopefully you reinforced that frame at all its possible failure points. also, find a liquid polymer to fill the chassis tubes with that will retard some of the harmonic vibrations that will reak havoc on your chassis and persons.

looks good so far.

well i am pretty sure i can build a motor. 4 or 2 stroke. have never had a problem with any motor i have personally built. but my yfz motor was blowing up and i wasnt turningthe wrenches. but never the less. i prefer 2 strokes any way. they are more fun and less common.

Be sure to keep us updated on this project. I have often thought about a YFZ with a 250R engine. I just love the light weight!

i dont think its rebuilding thats the hard part... its shelling out twice the amount of money... i got a whole 250r motor for 250 bucks... i also could got just a bottom end for 250.. its also alot faster to go through a top end and they last alot longer then a 4 stroke... they rebuild them every race and some times they get more but back in the day they would run them for 3 years straight...
