Its a strange world we live in and things change even in engineering, for Honda all their cars for a long time had toothed belts for the camshaft drive and ran anti clockwise, now all their cars apart from those with the V6 engine are cam chains and run clockwise.
If I look at BMW with the bikes they now sell I was thinking of selling both my bikes and getting a new one as I can only ride one at a time and it's very expensive here in NZ to register them, my F800gs costs just on $600.00 a year while the R80/7 because its over 40 years old costs $60.00 a year.
For those that don't know registration includes compulsory ACC Insurance (Accident Compensation) as you cannot sue people here in the event of an accident, they seem to think that people with these old bikes only take them out once in a blue moon.
The F800 is 2008 but I hated the rattle from the timing chain on startup as its tensioned from oil pressure, I have fitted a aftermarket tensioner that has eliminated this.

Here is the question if I did upgrade it would have to be a oil head but am hearing stories re cam chains on those as well.

Just got back from a 350 km beat test test ride.
Not a hint of a leak, not even a minor sweat!!!
I left the front boot off so I wouldn't have to remove the clamp and stick my finger in the boot to check for leaks.
It felt almost preverted to ride around with my shaft exposed.
A few blips up to 100mph, but mostly not too much over-speeding because it's the start of the Canadian Thanksgiving weekend and the blue meanies are out radaring in full force to prevent road carnage fill their coffers.

Another surprisingly pleasant but unrelated note, my wife's klx 250 300 just turned 100,000km.
Never thought those little bikes were so tough.

Between the left side timing belt 4 cylinder Honda cars and the change to a timing chain, there was bunch of them that had the timing belt on the right side.

I personally have no affection for any BMW motorcycle that isn't a airhead.
If, god forbid, I couldn't ride a GS airhead, my next choice would probably be something Japanese.
A great bike to rent for a week or two would be a Ducati Multistrada, amazing bike, but I sure wouldn't want to own and have to maintain and repair one.

What is correct for a R80 or and R100 (Monolever) isn't necessarily correct for a R100GS or a Mystic/R (Paralever). The same seal is used for both, just the other way round. The change in seal was a general change of seal type applicable to all 5 speed gearboxes not a change that co incided with the change from Mono to Para. Just saying... if it seals (and stays sealed) well and good...

Oh hell no I would never again own anthor Ducati, I always wanted one and some years ago I did get a 900 Monster, holy hell the maintenance costs are horrific so I started to do them myself and purchased all the bits and bobs so no, as for an alternative to what I have I would if I could find one get a Honda CX650 Eurosport, way back in the 1981 I had a CX500 and did 13000 miles on it in 6 months, it never let me down and was so easy to maintain.
When I moved to NZ all I could find were used wrecks so I totally restored one and like a fool sold it when we moved to Australia for work, never been able to find one since.

Oilheads and even the transverse 4 K series have noisy camchains. The 05 K1200r I have has a part covering one end of the camchain/lower sprocket to prevent the chain jumping and it was a recall supply.. The way to go is to fit the later 1300 part or aftermarket.
The 94 oilhead I have has an aftermarket one already, but a 2002 R1150r that a friend had sounded like a bucket of bolts at idle, and not just at start up.

So, it's also been a modern problem for BMW...seems to take far too long to fix the production.

My first BMW was a K100rs it never ever rattled unlike the F800, got rid of the K100 as in NZ you are restricted in speed by our roads and speed limits 100kph max and I found the bike a bit too heavy for me, the F800 motor is in fact a Rotax and if you look at the manual for it the cam chain is very long so a small amount of wear will make for a huge amount of movement in the tensioner.
After fitting the aftermarket tensioner it's very quiet now.
