QUESTION, 800R big bore cyls....
when you big bore, an 800 / 1200 R cyl there is a sleeve put in correct?? the reason i ask, is i have a 800 cyl here, that is broken on the very bottom ( were it goes down in the case).
i just want to know, is this still a good core, or is it now a paper weight??

Sorry, no sleeve... it has nicasil imbedded into the aluminum. I have had the ears re-welded before on cylinders with a lot of machine work performed. If its just a stock cylinder, then its probably not economically worth it.
Check with Millenium Technologies. They may be able to fix it or exchange for a useable core.

thanks for the quick reply. this is what i was afraid of. it is one of the ears broken off, and i DO NOT have the piece that is missing.
it is a stock cyl. i was just wonering if it was any good for a big bore. ( thinking "maybe" they used a sleeve, and the missing ear was of no concern).
this will either just become a big paper weight on my desk then, or go in the alum scrap.

This is still a good core and a good candidate for a sleeve. If you slleve this cylinder it will no longer be nicasil plated (this is what SBT and several other remanufacturers do with their cylinders) If you have someone like Dan Lamey @ DASA do a BB conversion he also sleeves the cylinder, others Bore and re-plate. Depending on what you want to do...you still have a "good" cylinder. Don't have the ears re-rewlded and machined....it's not cost effective.
