I was wondering if any body has put a dirt bike motor on their 250 trailblazer and what motor it was . Or if any body might know what dirt bike motor would fit in the chassis with less work to the chassis than any other motor. thanks for any info u can give.

 

I haven't heard of anyone puting a dirt bike engine in a TB, but I have heard of them puting snowmobile engines in them. I personally wouldn't put a dirt bike engine in one, because there are so many other lighter frames that are out there.

 

There used to be a guy on here that had an 800cc snowmobile engine on a trailblazer, but I can't remember his name.
