Any hostiles in the area? magnetic anomalies? HAARP/DARPA?

PM me with your recipe for that disaster. It may save me searching for my right side noise.

[Mike Ryder]

Perhaps it idled into the long dark tea time of the soul?

Wow if that's the good news I hate to hear what the bad news is.

I hope that was all covered but in most cases I suspect what's lost will be difficult to replace.

I had a bad sound developing on the right side of the engine. Removed cam and - here you go, the same picture with the exception that only half of cam and one follower is broken - the exhaust side.
For the intake part all seems well. Maybe that's why the sound is not that loud compared to videos in this thread.
I wonder if it would be possible to fix the cam somehow (welding/grinding/hardening)?

Also would be interesting to find out the cause of this problem. I would rule out the wrong oil, lack of oil and prolonged change intervals. Normally I keep valve lash on "tappy-happy" side...

I was reading this forum and went to my garage later to look at my GS sittting on it sidestand. I am not a mechanic and I do less and less wrenching as I get older. But it occured to me that with the bike on the sidestand could a little lubricating oil be draining out of the right side head. Most owners dont keep their bike on center stand, we just get on and fire it right up. If oil does drain slightly from the head when leaning on sidestand I could see it causing some of the issues shown in the picture over time. I would be interested to know if I am way off base, if not I may park my bike on the center stand more often I am a new guy, thanks for all the great post!

I've also had three other bikes in the workshop since with the same wear
The strange thing is the cams on other side of the engine have been perfect.

Knocking noise from the R/H side - R1100 50K miles.
Cause = Worn cams, cam followers, cam/rocker holder and rocker arms.
The cylinder head after all the rocker gear and camshaft has been removed

Cam/rocker holder.

Cam and cam followers.

Camshaft.


Cam followers in the holder.

Cam followers

New cams and followers

Thanks Steptoe I now after several attempts to silence the right cylinder have a new place to look.

I quoted your hole post because I felt it needed to be (Great info Thanks)

[Gintaronas]

This is what i found (one cam and one follower are broken, exhaust side) Sorry for crappy pictures.
BTW, my bike's mileage is about 116,000 kms.

Mike

Any speculation as to the source of the fuel leak? Was the bike equipped with QDs?

Any recent fuel system maintenance?

How did the insurance claim work out?

My input from talking to Mike last week.
-I believe the QDs were updated all-metal ones.
Just speculating now but I've seen the plastic high pressure fuel lines on the R series bikes break on occasion...particularly when they get old or are smacked in just the right way.
Several years ago there was a tale of a GS rider in Southern Oregon who noticed his right leg getting warm while on the freeway one day while riding....apparently he looked down at his leg and saw a trailing flame that would catch up to him when he tried to slow down. Eventually he stopped and was able to get the flame out....I believe this leak was due to a bad o-ring or QD.
So, inspect your fuel lines, injector lines and QDs. And update the plastic QDs to the metal version and carry extra o-rings, injector line clamps and a dual barbed fitting to splice a line without a QD or in the event that one should fail.

[vintagerider]

The weakest point on the 1150 black nylon fuel distributor is the plastic injector cap. When injector cap snaps off you can remove the plastic injector retainer/cap and connect the remaining stub of the nylon line directly to the top of the injector with a bit of 5/16 f.i. rubber hose and two clamps (Steverino repair mod). The 1100's had metal caps btw. Penny pinching like this by BMW really affects ones confidence.

Unless he left his engine running would would not think fire as a result. The hoses can leak when they are old, hard, but usually just an annoyance and paint damage. Hose is cheap, no excuse for not changing it every 3 years. Have read on here advice to "just add an extra clamp"

Def, you might ask Goober if eliminating the pressure side QD with Wix 33323 installed under the front frame head might not be such a bad idea after all :) Resulting hose run is actually shorter and more direct than stock.

If the engine was off then a return line QD failure might still wet the header but usually won't burst in to flame. Foreign fuel more inflammable?
