No, you can send the outer cover for polishing and still do the layshaft bearing.

There is debate, Mikuni will give you easy start and reliability but lack some of the top end vs dual carbs. Search the forum and you can get lost in Mikuni-Amal threads.
My bike came with an ancient Mikuni, I use it and it works well if not a bit rich. I have tried all sorts of jetting, slide combos and consider mine a work in progress. For now it gets me down the road fine.
If it's what you've got, mount it up and see if you like it, if you don't, try the Amals. Now you have 3 carbs to yell at.

My dad said the same thing, you lose a little on the top end but everything else will be good. Plus I think it’ll be easier and cheaper one vs. two.

Opened up my gearbox today to replace the layshaft bearing. Everything looks real good as far as I can see. No chipped or worn gears and no chunks floating around. Kickstart pawl looks good too. I played hell getting the layshaft out. Had to heat the back of the case with a heat gun for quite some time and then it wiggled out like a loose tooth bringing the bearing with it. Cleaned up everything and called it a night. Any tips for getting that bearing off?

Bearing splitter and some heat on the inner race.

Got the bearing off with a bearing splitter as gortnipper suggested. Thanks. New bearing installed and gearbox assembled. Progress! I think the bearing I removed is one of those bad ones.

Haven't had much time to work on the bike lately because I've been doing a lot of overtime at work. Tons of side work also. Gotta make that money to spend on the bike!
Items to send to the polisher. Am I missing anything?

Grrr! I knew someone was gonna say that...but, but, I don't wanna tear apart my wheels! I'll do it anyway. It's almost like I've become a slave to my Norton. Or as my wife calls it, my second wife! Lol!

I would polish them myself if I thought I could do an acceptable job. Fortunately I know my limitations so off to the polishers they go. I’m going to get new rims and my rotors blanchered ground so it’s got to come apart anyway.

Your photo catalogue is really comprehensive. It's cool being able to follow your progress visually as well.
Don't lapse on your photo records...you won't believe what a great reference it is on reassembly and years later.
