docc

I had to look this up. New term for me. Always learning here . . . "DLC Coating stands for diamond-like carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance." (To my novice mind, this sounds like a very hard, but thin, brittle layer.)

LuckyPhil, the link you sent on the roller conversion set me straight. This doesn't convert the tappet, but converts the rocker foot, itself. I like this idea! http://www.baisley.com/rocker_service.htm

So, you made a tool and got the tower nut (castellated nut) #18 off, but #13 will not come loose? Possibly treat with penetrating oil and apply some heat? The mixture of 1/2 acetone and 1/2 automatic transmission fluid is excellent for this penetration.

LuckyPhil's rockers with 0.003" wear at 42.000 km/ ~26,000 miles: (Phil, is that an intake/ exhaust L -> R, or what?)

So, with over 100,000 miles on my flat tappet Sport, when I set the valves, they are actually looser than my feeler gauge is telling me? If so, I wonder how much looser? Could be docc. When the rockers wear its simple not enough to slide the feeler in there because you will almost certainly be measuring on the unworn portion of the foot. To do them accuratey you need to set the gap to the worn part of the foot. I guess mine had around 3 to 4 thou wear on them. There is a place over in the States that does a nice roller rocker conversion for around 700USD from memory. Not only do you eliminate the wearing foot issue but you get more accurate cam timing as well. Ciao Ciao 3 thou is a lot for those miles. I don't mind running my valves a little loose, but . . . So, use a feeler gauge the width of the valve stem and most carefully align it with the groove worn into the rocker foot?

This song just came on the "radio" and I've been cooped up with the flu all week in quarantine. It's all I can do not to crank it up and blow the roof off!

From the web: "Bob's your uncle" is a way of saying "you're all set" or "you've got it made." It's a catch phrase dating back to 1887, when British Prime Minister Robert Cecil (a.k.a. Lord Salisbury) decided to appoint a certain Arthur Balfour [his nephew] to the prestigious and sensitive post of Chief Secretary for Ireland.

The natural history museum in Chicago is wonderful, too.. but.. if you are a motorcycle guy, Barber's is beyond amazing. I remember a "G50 Matchless" displayed in the Art of the Motorcycle exhibit at the The Pyramid in Memphis. (It was not the same burgundy tank G50 displayed at the Guggenheim in New York). This one had a race history and the story was that it blew a sealing plug from the crankcase and the racer sealed it with a Krugerrand. Being an ounce of gold, that rates as a dedicated repair! Looking at these engines, though, I don't see a place to fit a Krugerrand in the Barber engine. What gives?

The manual states that #18 is to be removed first using the "special tool." Once #13 is removed, the "special pinion puller" can be applied to remove the pinion.

And the matching ECU?

when did they put a walking bridge in the back of the museum? Was the water always there? They've been physically working on this "addition" for the last couple years and debuted it at the last Vintage Festival. This is the "back" of the museum taken from across the track. The addition is the entire four-story cube on the right. When the walk-way was completed, many (including me) had the impression the addition was going to be in the infield, but this is how it resulted. So, the waterway is new and gathers a multi-tier waterfall along with the usual variety of statuary and landscaping. The walkway continues up the hill, in the infield to a viewing platform where so much of the track is visible, it is absolutely stunning. There are "surprises" everywhere.

I'll not forget the Museum of Science and Industry in Chicago, but there is so much to wade through there and still never get this close to a cut-away Matchless . . .

Well, at least the two Spine Guys were quite taken by it . . .

We got where we couldn't pull ourselves away from the Vintage Festival to spend the day in the Museum. I don't mind being inside for hours and hours when the weather is crappy. Not in a place like this, anyway! Numerous Guzzis of all sorts on display, but this Ghezzi-Brian SuperTwin had us fascinated for quite a long time . . .

I recall, some years back (perhaps about the time Piaggio took on Moto Guzzi) it was "reported" that all of the spares were sold off. Some said HMB-Guzzi in Germany got them all. Perhaps this was just some urban legend. Or was there some truth to it?

No V11 valve covers? Seems there would be separate part numbers for each color used over the run. What part number are you looking for?

Here in The States, we have this rather dubious, informal holiday known as "Groundhog Day" that marks midwinter (February 2). While there is much pomp and lore surrounding this construct, it basically comes down to, "Let's have some fun and be happy winter is half done." In this spirit, a handful of us piled into a very fine late model Toyota and headed to the Barber Vintage Motorcycle Museum near Birmingham, Alabama, USA. Recently expanded and otherwise extended, the combination of the collection, the presentation, and the surroundings is purely staggering. http://www.barbermuseum.org/plan-a-visit/look-inside/ As an added bonus, there was a running of the 24 Hours of Lemons wailing around the track! This, somehow, resonated with our tight group of Guzzisti . . . https://24hoursoflemons.com/ So, if you've not been to Barber, go! If you've been, go again! If you don't have any plans to go, Groundhog Day seems appropriate, somehow . . .

What? Your V11's Rocket Propulsion, Trans-Atlantic Space Displacement System is on the fritz? Check the relays . . . .

See? That proves it right there. I'm hanging out with the right people . . .

3?

. . . "driving" . . . "blues" . . . Got me out on the Sport, again . . .

Is it this?

"I love the smell of [race fuel] in the morning. Smells like . . . Victory."

That whole metric thing is just a fad . . .
