This was part of our line of thinking when we started making changes to our stock '02 Sportster late last year. The favorite mod for Sporty owners is upgrading their 883cc motor with a 1,200cc conversion kit, and while it was tempting to do just that right off the bat with our `02 Sportster 883R, we took a different approach. All of these modifications were relatively easy and served to give us more bang for a small outlay of bucks ($906 total for parts). Beyond that, once we did add a 1,200 kit, we'd already have a performance platform ready to take maximum advantage of the increase in power gained from the conversion.
That time has come. We took a trip to Harley-Davidson of Fullerton/Anaheim to watch as it bored out our cylinders, then added James gaskets and a 1,200 piston kit from JE Pistons. JE is known for its high-performance pistons, and the James aluminum gaskets seemed like a great way to seal the deal.
