Hi, I'm new to the forum, so let me start by saying that I am the owner of a 1995 Polaris Xplorer 300 with a 350 2stroke motor in it. I bought it like this, I never did anything to it. The wrist pin bearing went out while riding it one day, and the rod slapped through the casing of the motor. I need a new engine, to say the least. I am wanting to put a 4 stroke engine back in, because I have had very bad luck with 2 strokes. What can I put in that will relatively easily bolt up? I can do some modifications, but I really don't want to be cutting the frame and such. Any ideas would be appreciated.

 

Ive got a good 97-425 motor that would probably work,everything is there , and still together, think I still have the carb for it too, I built a 5oo motor and put in the bioke, 425 motor ran very well before I pulled it.
