I work in a machine shop where we bore, resleeve,do porting, grind heads, etc etc etc. most banshee cylinders are nicklesealed, and yes you can bore them out as far as .100. (paperthin wall). We bore them with a diamond boring stone, if you want to them (or need them) bored say .20 over, we bore them .10 clockwise, then .10 over counterclock wise to reduce friction going around on one way of the cylinder. etc.

you guys have it all wrong. banshee cylinders are NOT nickelsealed. and im about 95% positive you cant bore nickelseal cylinders. you have to have them replated.

They are a standard cast iron sleeve, pressed into an aluminum cast cylinder.

 

You can have them bored anywhere.

they are not nickel sealed. anyone telling you they are is a fuckin idiot. your local yamaha shop can bore them. and no you cant bore nicle seal cylinders. most guys that have them in dirtbikes just re ring and put a new piston in. if the cylinder walls are fucked up you have to have them re plated. but dont worry becuase your banshee cylinders are absolutely not nickel sealed.
