CB350F Restoration by royhall (NOW FINISHED)
Bryanj:
Problem you got is I think Black is the thickest shell so if the pins are worn you may have problems. I wouldn't bother with the casing holes as unless the shell has spun there is no wear and at least its not like Fords where they have a standard hole size and a plus 10 thou hole size for if the boring machine hiccups then they dont scrap a block---makes buying parts a b*tch
I have built several 500 and a couple of 750's(way back when) engines with all black shells and run in carefully with no problems and i know the race boys used to go one thinner than stated to get more oil round and not need bedding in.
When you work out the difference between smallest pin largest hole as against largest pin smallest hole i seem to remember you are in the tollerance range of a grinding machine anyway

There's the AA Blue shell that's available in the States.
Bryanj:
If they are available, use them mate, only ever seem blue colour on Wing shells, but then never had to fit shells to a 350 or 400 either!!
Bryanj:
This place sez they have 7 AA shells in stock but $15 each(also 5 B 13316-333-003 but no black)

Hi all.
More on the shells later when I get a chance to measure up. Been using the fine weather to get the engine painting out of the way. Had all the castings bead blasted then a really good clean out with heavy degreaser and a flush in hot water. Got everything masked off ready.

Spray painted everything with Simonize aluminium finish engine enamel. Looks okay and a nice finish. It sprays really well without runs etc and dries fully within 30 minutes. Gave everything 3 coats.

Wife's away this weekend visiting daughter No.2. So whilst theres the opportunity to get it all in the oven to cure.

What she doesn't know she cant complain about. Got in real bother last time with the 750. Had a price to stove enamel the castings £225 plus VAT so that's a big saving. £21 for the paint, £15 for bead blasting, £12 for degreaser. Well pleased with the results. Next installment will be the engine going back together.
