only the one i had was equipped with yoshimura pipes and a power commander. It's kawi's z-1000 for those who dont know, and let me tell you! jeez! being my first time on a crotch rocket, i took it pretty easy, but it didn't take long to get comfterable. right when it hits about 4000 the power starts coming in and you start to smile, by 7k it's like hitting the NAWZ on need for speed underground and by about 9k (the highest i took it) youre screaming your ass off lol. the damn thing pulled harder then any car ive been in, and it was an absolute blast, but with my luck i'd probably die on one so i dont think im gonna buy a bike at this time, but i just thought i'd shre my experience
p.s. oh and would any one know how much an aluminum headed long block 302 weigh (roughly) i need to get some qoutes on getting one shipped.
