I just want to say that I'm no expert, far from it. There are others on here that can give you a lot better advice on porting than I can. You should start thread asking for advice on porting a x-torq. If you're lucky, one of the experts will chime in and advise you.Have not, just tested compression out of suspicion and sure enough she is worn out. So I figured I'd just order up a rebuild kit and carb rebuild and see how it goes from their. But figured I'd ask you experts if I should do more while it's torn down.
