Well remember what they cost previously. They weren't cheap to say the least but they were better than original and they were new. And they did not cost half the bike. Maney bits were not cheap either but he sold what he made. There is a market.

John knows about costs and always considers this, all while making a product best on the market. Perhaps some will balk at the price, but others will be quite happy quality heads are available again... present company included.

Lovely new high tech work. Now, time to get to it on the CYLINDERS. :cool:
We have already produced billet Aluminum cylinders with nikasil bores. They are currently being testing. Over 2,000 miles on them currently with no problems. We are working on inserts for the lifters now. From experience we believe these cylinders may last 60 to 80,000 miles. So we want a better pocket for the lifter to prevent wear

I tip my hat to you on both products. Two of the advantages of nikasil jugs are there are no sleeves to slip or turn and no sleeve
can give the same amount of heat transfer a coating can.

Do tighter piston to bore clearances make the motor faster when it has got a stroke which is 100 miles long ? The rings do the sealing, friction is our enemy.

here is another question. what is the possibility of you offering an overdrive ratio on your belt drive? hopefully in the 1.9 or 2.0 to 1.

Less rattle / slap. Better heat transfer. Less rocking (which can reduce ring sealing).

There is no increased friction (well, not unless you go TOO tight)!

Friction is between rings and bore, not piston and bore.

Maney cylinders are being made by Andy Molnar,with,and without liners.Unless I am very much mistaken?What I am waiting for is for somebody to start making Maney crancases again.Nice work with the heads by the way,I may be in the market for one for my spare motor,to go with the Fullauto one on my race motor.

tonybsa, I did hear that there maybe billet cases ( like the ones that were made here in NZ) are going to be made in the USA by G81 Can Cycle, could be just a rumour though!

Ken found them for you already:

The cases do look like Maney cases to me, but they say they made there own moulds, so I dunno.

Molnar does indeed make some nice looking barrels, but they’re not Maney copies, they intended to be more of an OEM copy with more standard looking fins (whereas Maney barrels were Dunstall copies):

Well done Andy, he seems to be stepping up to the plate...

The finish on those billet cylinders is magnificent - will your new heads match that standard of finish? If so, what a stunning looking top end it'll be. A bloke would be tempted to buy the set, just to have the prettiest Norton engine ever!

Careful!
There's nothing in common with Maney and Molnar barrels, other than their intended purpose. Different castings from a different source.
Maney adopted a Dunstall lookalike design which have a similar appearance to the 750/810 flanged barrels but are actually through-bolted with exposed bolt shanks. I believe this was done to satisfy the Classic Racing 'period correct appearance' regs at the time.
Andy Molnar's barrels are more like 850 barrels as the regs aren't as stringent these days.

I believe Andy has done OEM pattern crankcases in the past, and is working on race quality ones at the moment.

I suspect if more potential customers made themselves known, he'd work a bit harder on them!
