Old people often say that they regret more what they did not do than really did.
I'm sure this is a situation like that. Getting a beautiful well working, long lasting billet block will not happen that often.

I have a billet block waiting to be used again.
I cannot decide which engine. Back on the now very well running K6 with APE lightened crank with Carillo rods Mike assembled or another slow going engine build with stock crank and super rods. Both have undercutted trans and case milled to fit the wide cylinder sleeves.
An easy choice if I have to take off the 970cc cylinder the bike has now which should be the best option giving most power. The other build has my old VM29 carbs.

But I am very happy to have a billet block. Next time with gas ported pistons. Maybe something to consider?

Megacycle 125-75 cam a must! My K6 has a very nice idle and even throttle response up to after 8000rpm. This despite rather high compression.
Pistons outer flat area flush with head mating surface without base gasket.

Thin RCS gasket 0.001" (0.25mm) and thin MLS 0.003" (0.76mm) a good combo getting a squish of 1mm.
My ported heads that fits have 23.7cc  chambers so pistons have had higher domes 12.5:1, milled down ca 3 mm.

Photos of later gas ported piston and the first test with billet block in frame thanks to Frank's frame kit.

The final assembly with only the inner 4 cylinder studs. 
Easier to fit the 2nd clip on each piston and make sure that the rings  compress as the should.
(The other studs came in after the block.)

See Mike's Billet block thread where I documented my build and findings. Grind the inner corners of the oil rails ends to a rounded shape one thing to avoid pinched oil rail.

You will build s few engines with undercutted trans, APE Ultra crank or similar, german CCC primary chains etc etc?

My K6 has those primary chains. Almost no stretch after 45.000 km. Most of it +100whp.
Ca: 65.4mm last measurement.
A little less than 65 mm direct when assembled.

Corresponding with my machinist....he may be able to use his friends shop for the very noisy operations. His friends son now runs the day to day machine shop so he has to clear it. Anyway....project isn't dead.... just waiting to hear.

When ever you need money, reach out..
I don’t expect you to carry me until completion…🎯

Speaking of German primary chains, what is the availability? I know we have lost Ted this past year.

Thanks....much appreciated!

I don't know Jerry....I haven't been able to find those original chains on the internet. They are the best IMO.

Have you tried asking Thomas (nippon), who was Ted's business partner in Germany?

....if this Thomas is the head of ClassicCycleCity then no! He don't sell this chains any more, was talking to him 2 Days ago.

Yes, that is the same Thomas. Thank you Georg.

Interested depending on the price.  Do these blocks take care of the oil seeping issue with oversized bores?

I’ll let Mike answer you….😁 but there’s no sleeves in the block… Nikaseal bores….😇

If base, head and cam chain tensioner gaskets are doing what they suppose to do, no leak!
The billet block is a block with beautiful cooling fins Laverda style.

I also got the news about no CCC chains. I'm lucky to have a set for my ongoing build.

There is a long thread about primary chains you might remember.

 I have the K6 block with F2/APE transmission waiting for something exciting to happen to it. It would need a better rotating assembly though. I've been saving a 10,000 mile/10 oil change crank and a set of German primary chains from Mike for just such an occasion.
 

[MRieck]

I have some positive news. I found the original fixture plate for machining....a good start! My machinist got the OK to use his friend's shop for the loud operations. It looks like it would 12 units secondary to material price point. Working on final cost now.

Yes....no seepage as there are no air passages between 1 & 2 and 3 & 4. Blocks improve engine rigidity as well secondary to their design.

My machinist is out of the country until 5/15....I should have some info after that.

Me too! At least the increased tariff on material is on hold which is a positive.

 I used to see aluminum billets two to a semi headed up I74 to Alcoa in the Quad cities. I always wondered where they came from.

I wonder if Aluminum billets will be affected directly or indirectly by the tarrifs.

I must admit to a total ignorance of what the basic sizes are of aluminum billets that they saw blocks and slabs out of. A billet hemi or big block chevy block takes pretty big block of raw stock, some of them they increase the bore spacing something like 1/2". The Steve Morris SMX blocks Steve and Tom Bailey have shared a lot of details as they developed the process. They rough machine, then heat treat, then finish machine.

I'd think if their business depends on it they might try to arrange blanket orders that allow the supplier to buy into whatever the basic "block" sizes are before sawing.



A lot of this billet stuff I am sure there is a trade off of the value of the raw material vs machining time involved to slug out some portions and use or sell them vs just making chips.

Ebay listing: 10 Pieces 3-1/2” X 3” Long Aluminum Round Rod Solid 6061-T6 3.5 Bar Stock, $238 with shipping included is one example of how the cylinder bores as one example could maybe be slugged out and the raw material saved for re use or sale.

[MRieck]

I just spoke with my machinist and I will be having 6 blocks made. Price should be around $2,000.00 per block....I should  know final price later this week.

 I see Millennium had a fire and are out of the cylinder plating business right now.
