Honing barrels

A bit of a numpty question

I was wondering if the 1200's have a coated barrel liner (like the old 850 T3) or steel,  and if you can hone both types to glaze bust for new rings to be put in?

thanks

They are all Nigusil (Nikasil the Guzzi way).....as I understand it you can 'glaze-bust' them with a flexi-hone at around 240 grit AO ...only know this because my engine burns a fair amount of oil & one day (if I get around to it - I DO have replacement ring set ready) I'll likely go that way.

Thanks Paul, useful to know

Generally no need to hone but if you're re-ringing you can give a few passes with a boron ball hone if you wish.

Paul, are you sure your engine is burning oil? You don't just keep topping it up to the 'Full' mark on the stick? If you do that it'll just pump it out.

No, always at or even below min..... it's always burned oil (piston crowns were clearly oily when I rollerised it), & sometimes can smell burned ester oil when I pull up at lights.... Initially I thought could be 'worn' due to two failed sets of flat tappets in it's early life BUT I checked bore & didn't seem too polished - valve guides checked & replaced valve oil seals when I rollerised as well.

hasn't affected it in any other way & it's managable level of burning, so new ring set & head gaskets just sitting there waiting until I feel like doing it.

Weird. It'll be interesting to see what the old rings look like.
