Do you have more details on this? Was the issue that HMB Guzzi had not previously stated that they are not associated with Moto Guzzi?

It seems that this does not change anything - they have mentioned this:

 The HMB GUZZI owner is in progress now changing the name to HMB-MOTO to avoid trouble with Piaggio lawers. There is a thread from him in the German Guzzi Forum (more than 3600 members).

(sigh) I was offered one for $3500 a couple of months ago.. Told him I was not doing big blocks any more and he should put it on BAT.

Damn, I'd part it out before selling it that cheap

Can I have this bit again please mate.
You make good sense, but this bit has got me baffled.

The combustion pushes down on the pistons and pushes up on the combustion chamber. In turn the cylinders are tugging outward on the block on the left and right sides. After many miles this does widen the block a bit. The extra width is subtracted from the height. Hence the crank to cam distance is shortened and replacement timing gears are normally one to two deviations smaller then the originals. Duane Ausherman went into this in detail in his vintage BMW site.

After a lot of running the compress / explosion pressures widened and shortened the block.

Harley did the same thing  once their popularity skyrocketed so they could make money off the name. That's when the Harley bath towels hit the dealer shelves.

Therein I see the difference.

I’m an artist. I make a piece of art. I don’t want that art going onto any merchandise without my consent, because I deserve the profits. It’s my art, after all.

Now… when it comes to building of communities by collecting people around this art who will eventually want to buy my controlled-license merchandise.

Priorities. It’s not like Luap and these other folks are making a killing off this.

Finally got a NOS rear main... and about to put the motor back together... until!

So I spoke with someone that had worked on my bike back bafiore I had it.. went thru three rear main seals. He told me to double check the crank for pitting where the seal rides.. and it has some. Spoke to the machine shop that "checked and polished it" and he claimed he was surprised his guy let it go like this and advised me to being it to a crankshaft specialist they send them to for grinding... if they need it. So that guy, who really seems to know... measures the ring bearing area as out of round... showed me. Also the timing side is out of spec. So both of those need to be taken one undersize, and now I need a front bearing and new rod bearings(anyone need a brand new standard set?). Regarding where the seal rides... three options. Install the seal just a 16th inward our outward so it rides elsewhere, or get a sleeve/bad for the crank and he'll install it. He also says he's not sure that the way it is actually would have hurt the seal.. it was probably one of the other issues causing the leak. Anyone know where I can get a band/sleeve for that part of the crank? Also... for what its worth, probably going to get a partial refund form the machine shop... owner seems decent and they had a good rep... maybe the tech looked at mine on a Friday afternoon, lol. But either way, so thankful I caught it now! They guy that had worked on my bike before said it was mean to be that we crossed paths that day... and I can't disagree.

Hi Huzo...not me...my plastic bits are all original since I bought the bike from Mike at MPH.  Some other lucky soul has your Tupperware!

I just went through my messages.
It was iHONK (Randy) in the ‘States. He was very appreciative, nice guy….

My R60/2 ('66) had an aluminum cam gear mated to a steel crank gear. I sold the machine at 100K miles. Gears still looked and sounded okay. There's a reason antique clock makers ran metal against wood and had good service life.

I seem to remember that BMW made their blocks and measured the crank to cam center distance when finished. The blocks were marked with a code indicating the deviation from perfect. I think there were 6 steps.

BMW made the timing gears in matched sets and measured their center distance deviation from perfect. The gears were marked with the same code as the engine. The gears and engine blocks were paired by code at assembly.

After a lot of running the compress / explosion pressures widened and shortened the block. So replacement gears had to be ordered smaller than original numbers indicated.

Ural tried a similar approach with the numbered blocks and gears but the Russian product wasn't precision in any way. Russian gears were hardly round so clearance was set to the tight spots. Their Herzog gear upgrade was a great improvement.

From my FWIW department I ran my Valtek chain tensioner for 80K miles before replacement. It was still functioning but probably would have worn through at 120K miles. I replaced the timing chain and crank timing cog as long as I was in there. It was a bit past 100K miles. It got a bit quieter and timing a bit more stable after the attention.
