Valve adjustment on a model 2013 motorcycle?

I'm thinking: Who whant's to do that kind of work in 2013? All engines should be designed so this is no longer required or do you also adjust your car engine valve clearance?

I don't even like the thought of accidentally dropping the cam assembly in the dirt while trying to change a shim.
(assuming that you carry a selection of shims with you on your trip or can find the right one conveniently...)
A valve cover can be wiped clean easily if needed. How do you make sure that you get all of the grit out of a cam assembly after dropping it in the dirt without a parts washer handy???

We can assume the new water boxer will have the same cam setup as the latest OHC GS's which do use shims for adjusting clearance, but the cam followers are spring loaded and push to the side for shim removal. You don't need to pull the cams on the OHC boxers. Not as simple as the old threaded adjusters, but not as bad as it could be if you had to pull the cam.

Not many bikes have non-adjustable valves. Those that do are very heavy and not the most efficient.

Like it or not, some level of valve adjustment will be in our near future.

Hopefully experience will lead BMW to extend the valve checks on the Camhead motors to at least 12K miles.

The CB650SC & CB700SC Nighthawks had hydraulic valves,
got great gas mileage and had light, non-exploding shaft drives.

Right, and about 80hp, and doggy. A far cry from a modern bike. What does the driveshaft have to do with anything? Apples to oranges anyhow.

Inbetween

Gents,

Due to relocating I recently sold my 06 GSA. Having ridden 40 000 kms hassle free on the air cooled motor, often at 46 - 54 degrees C due to living in the desert I am wondering whether to wait for the GSA version with a water cooled engine.
Speculation has the standard GS liquid cooled for release last quarter 2012. How soon after that will the GSA follow?

Your thoughts?

For what its worth my dealer said his BMW sources have confirmed the GS and GSA will have cruise.

With the new Tiger having it stock BMW would be crazy not to offer it.

Your guess is as good as anyone's. BMW certainly isn't saying, but you could wait till the EICMA in the fall (usually Nov.) 'if' there is a debut.

I didn't want to be left hanging, so I got the 2012 camhead. If and when BMW goes water cooled with their Boxer, I personally don't see any difference in it and a KTM. So, I'll be heading Austrian if a Water cooled Boxer rears its head in the shape of a GS.

YMMV.

This thing looks so big, how much bigger will the GSA be or could this be the GSA?

Sorry, but having been a Honda mechanic when there were lots of these around and coming in for me to service, I thought the Nighthawks (CB650SC and CB700SC) were an excellent machine. Quite powerful, agile, responsive and fun to ride.

I like how the swing arm is displayed prominently when my bike is on the side stand. They switched sides so now it's hidden.

Agile? I have to admit I had not ridden one, but if they are anything like the 750 Nighthawk, they are neither quick nor agile IMHO. Maybe I just have a different level of expectations.

No, they're very different. Shorter wheelbase (IIRC) and faster steering.

CB650SC? Powerful and fun, but not agile or responsive. Every non-cruiser I've ridden could run circles around my '84 Nighthawk.

Wait, what is this thread about?
