[jk99z24]

i have removed my engine from my 02 ex for a rebuild an have a line on a good 450r motor is it worth converting over or what possible problems will i run into?

it may be hard if you don't have the a welder handy or have some mechanics. you need to add a radiator,plus align the carb to the air box. u will need to make new motor mounts. The best way to start is the buy the front motor mounts from atv four play and go from there.
