motor mount kit for 4-stroke motors?

[250R Baja Rider]

A friend of mine asked me a question I couldn't answer.

He just about had it with 2-strokes and he wants to install a 4-stroke motor on his 250r frame. He doesn't want to sell the whole bike since he dropped a ton on money on the R already.

Does anyone make a motor mount kit to do a conversion?

Any help would be appreciated...

none that i know of...

and if he cant keep a 2 stroke running i doubt he will be able to make the mods himself to put in the thumper.

Racerx573 did that to his R, he put a Yz426 motor into an aftermarket 250r chassis.
