this is what I know on that kit... its a big bore kit.. it has a big ass sleeve in the cylinders.the guy I got it from said they were a 69mm, now with that trinitys big bore kit as the 420 comes with the 69mm piston..you can go from 69,69.5,70..up to 72mm piston as they claim. me not being a knowledgable banhsee person might have not described what I have for sale the best that it could have been..so to you banshee smart ass people that want to correct me go ahead explain.. I dont have a +4 crank I never had this set up on my bike got it..then got a bigger better set up for a good deal..so this is why its for sale. sorry for the confussion.
