thinking about doing this over the summer on my 99 zrt... is it worth it? would I have to beef up the motor for this? probly going to 136 also. This is a trail sled also, If you think it's worth it where should i get parts?
I think you would be better off with clutching and porting. You need to contact Snow800 on here, Mike will give your sled a "tune up" and you will be happy.
