Kitty Cat Snowmobiles

Is anyone selling or advertising a drop in 4 stroke engine for the Kitty Cats? Just curious since many of the vintage 2 strokers would probably be better off as a paper weight.

Get out the tape measure and put on your thinking cap. There must be options but I don't see anyone advertising a drop-in 4 stroke kit.

A 4 stroke engine replacement job requires some engineering any way you slice it.
