I just picked up a 93-94 xlt. I was wodering how do you tell the difference between the 580 and 600? I have a pink/purple head cover that says xtra light triple. It is also a Speicial. Whatevers that means.
Not much difference. If it's a 93 or 94 the stock engine is a 580 (579cc 64x60 bore and stroke). 95 they bored it out to 65x60 or 597cc which added about 2hp. If the engine was transplanted then it would be difficult to tell.
