Methinks it will run, perhaps just not all that well. If you're just replacing a rusted-out stocker, it may be worth doing just because it's handy and paid-for. If you seek performance gains, you will need to do a bit more reading. Unless you have already adapted the header to the M/C chamber, it'd probably be easier and a whole lot less work simply to locate a nicer/newer stock pipe. The Elite ES pipes should fit and are reportedly an upgrade for the Spree pipes. They turn up frequently on eBay and here.
