Alright I'm new to this site, so if the question was already asked then please direct me to it. I have an 05 XB12R and was wondering if anyone knew anything about bore kits. I think I've seen some in the form of 1250 and on up. Any help would be great, thanks.
this is the company to buy from if you are considering big-bore. http://www.nrhsperformance.com/ekitbuell1200.shtml
a friend of mine just put a 1250 kit in his x1 lightning and he loves it. they also sell an 88" kit around 1442 cc or so, but that kit requires case boring and the 1250 is just a bolt on kit. depends on power goals and cash flow, both kits are rather expensive, but my friend sent them his heads and they did a port and polish on them as part of a package deal. hope that helps
