[KX4FIFSHEE]

I have come across a complete top end, my compression is at 90psi and needs to be one. I would like to have 2 sets of cylinders and heads taht way i can just swap over and not wait for the machine shop time.... So, i came across this : set of standard bore banshee cylinders off of a 2004 350 twin these are trail detailed ported very minor basically cleaned up with a cylinder head that has had .075 surfaced off it with the squish recut to enhance performance also they come with a set of pistons rings circlips top end bearings and wrist pins these cylinders are nice take a look upgraded to cheetah motor is reason for removal..can be used on 350 standard and 4 mil strokers as well Does this sound like a decent deal at $300? I will be doing strictly desert riding for now and i have full pro circuit exhaust with K&N's on the carbs...
