250r conversion

[Martin Blair]

well it looks like i might be putting a cr250 motor in my 400 this year. heres my plan, to get a cr250 motor, a denton radiator, cr250 carb, and lrd pipe. But does anyone know if a 250r pipe will fit on a cr250 jug? or do i need to get a new flang machined?

Also do i nned to modifie my swingarm for this?

Thanks.

nice quad...how many time u have to weld the frame?

[hondaracer3x]

I welded cracks twice, then I gusseted the frame, and I haven't touched it in over 6 months

Sounds like a project! If i had the money i would do it!

yeah money thats why i wanted the cr250 motor there half the price of a r motor, i can buy a whole r for the price of r motor.
