yz conversian to 300

[redrider69]

does the engine of the yz 80 bolt right up to my 300ex frame or will i have to do some moddifying i found a cheap yz 80 motor and wondering how hard the conversion is and if anybody has any pics or anything all help wanted thnks

i'm sure there is some fab work needed, but it shouldnt be much, there are quite a few of cr80 300ex's out there

you'll probably need some new mounts.. will be a sweet project though. i'd wanna stick a 125 in maybe.

i think alot of people do this conversion to run the 90 mod class at the gnc's
