Great stuff fella’s! Enjoyed researching this topic. This gear opportunity has been fascinating in gaining a greater understanding of ignition camshaft drives - there’s a helluva lot more involved I had no real appreciation for to such a granular degree. Learning new understandings on concepts which seem, as Docc puts it, “non-intuitive” can be quite humbling! Like for example, I’ll never be quite so unthinking of my RPM’s as just some simplistic spinning speed ever again! “Periodic combustion impulses result in rotational speed fluctuations of the crankshaft. Ignition and combustion within a cylinder cause a rapid rise in gas pressure and an angular acceleration of the crankshaft. Gas compression in the next cylinder causes immediate deceleration. Torque pulsations result in crankshaft torsional vibrations which reach the camshaft(s) and auxiliaries via belt or chain drives.” https://www.rotec-munich.de/wp-content/uploads/2019/12/torsional-vibration-measurement.pdf As usual, Mr Cameron always offers a compelling motorcycling perspective. https://www.cycleworld.com/story/bikes/about-motorcycle-engine-cam-drive-systems/ It’s Christmas Eve & the missus has got some concert playing on the box - so Merry Christmas!

...so it actually has ONE red Moto Guzzi eagle valve stem cap. And in other news, it blew a 15 amp fuse twice, so that means it's ready for the lift and some attention to the electrical system along with all the other fun. I've been collecting bits from various stashes in the garage, and some shiny new things like Rizoma tanks and Pazzo levers. My favorites are the forum-made bits like Chuck and Phil's shift extender, and the drilled-out cush drive rubbers. Of course, I'll be popping in a new unbreakable spring when I do the shift improvement stuff. I also dug out a bunch of previously powdercoated bits from my aborted Champagne LeMans project. The candy-apple red frame plates and covers look great with the Glossy Black Nero. Speedhut says my gauges will ship next week. I got the remote clutch-bleeder line that comes on CARC bikes. Gonna try to fit that while I'm in there. '

These German cars used to be the "top of the line" . It seems as though they loaded up on a bunch of unbridled engineers. Then they went wild on engineering stupid $hit . They do ride, drive and perform SUPERIOR . Then when they start messin' up , get ready to buy a dependable car while your Teutonic POS is in the shop .

tomorrow my mom loves this one. When I was a little bitty kid, she'd play it. She'll hear it tomorrow. And there's this version for above and this and finally...the wall of sound Christmas Eve at my house.

blueblueblue Christmas . . .

Neil looks like a happy camper. Graham and Steven are having a good time.

Hands down, the best car I ever owned was a BMW. Hands down, the worst car I ever owned was a BMW.

Haha... chortle! You really have missed your natural vocation - you probably would’ve made a half decent stand-up!

The V85 is just an example of the vehicle manufacturing process these days. A pressed up crank with plain bearing big ends, cam drive sprocket machined into the crank main shaft and those are just the things I know about. Cars are the same, friction drive cams etc. The Lego world of automotive engineering. My DD Ford Escape recently at 85,000klm and 5 years of age had an about to fail tail shaft centre bearing. I troubleshot it in plenty of time and due to circumstances just took it to the Ford dealer to fix it. So the failed $60 bearing on the 2 piece tail shaft isn't replaceable, it's either remove it and take it to a tail shaft specialist for a $450 rebuild plus removal and re fitment costs or the Ford replacement of the whole assembly for, wait for it, $1700aud plus labour, so $2000aud total for a $60 bearing that's failed at less then 1/2 life. Welcome to the modern world of the mass produced automotive product. Now I see the latest small blocks have the EFI ecu along with the TPS and various sensors built into the throttle body as one unit. Got a running issue you want to sort out? Good luck with that in the future. A failed sensor in 4 or 5 years time? Yes sir that will be a gazillion dollars for a complete new ecu and throttle body assembly and we can have one for you in 3 weeks. Think it's a rare event? I've replaced a Guzzi ecu due to a failed baro sensor and I'm not alone by any stretch. How did we get here? well part of the reason is that people allow themselves to be blinded by the "bling" and aren't interested in the "engineering". Too busy being mesmerised by the latest "connectivity" or "style" or free servicing or spec sheet shenanigans. In other words it's Style over Substance and the manufacturers oblige willingly because it's more profitable for them to churn out some piece of bling that has a service life before major issues of 5 years than produce a sound piece of engineering that will fill it's intended roll for many years and miles in a trouble free manner and if the odd unfortunate thing happens is capable of being rectified in a cost effective manner with a minimum of technical fuss. It's the world of accountants and profit margins over engineering. It's sad and pathetic but the consumer only has themselves to blame. Ciao

this one will grab you. I think he used to sing gospel. Electric bass kicks in That's why he's the king.

Or simply "Per un capriccio" . . .

With respect to the piston motion the crank isn't accelerating/decelerating it's the piston that is for a constant crank speed not the other way around. At low engine speeds like idle the crank in a 90 deg V twin with have varying acceleration during the 2 cylinders full cycle but at 3000 rpm of so it will be on no consequence to the cam drive chain. Ciao

Do this exercise.. 1) Price up all the Öhlins bits 2) Add a little for Aprilia level QC 3) Factory Titanium pipes 4) A little extra for the paint scheme 5) Numbers built - Rarity value 6) Condition & mileage of the remaining usual shared componentry 7) Sheene’s X factor to round it off - Desirability to Women ...And pays your money ps. Guarantee whoever stole it for $7000 is laughing with delight!
