RE: Question on using suspension setting to reduce bike "verticality" on side stand - 3

When I bought my 1200 in 2017 this was the subject of a thread and the recommendation was to remove 20mm from the side stand. I took 15mm off and it made a big improvement and transferred it onto my 1250. I seem to recall one reason mentioned in 2017 for the upright side stand was that BMW did not want the oil to move to the left when on the side stand. Look at a GS and you will see this is rubbish.

For the benefit of newbies: as has been discussed here before, in the Chinese market the bike is actually provided with a shorter stand, so make of that what you will. As someone who's bike has fallen foul of the short stand myself, I find that pretty mind blowing!

Also, the forum admin, Holger (who?), contacted BMW about this issue a few years ago, and received an unapologetic reply from them, here:

Side stand swap (3)

The reply also alludes to the shorter Chinese sidestand!

That does make sense regarding settled oil prior to starting if you have ever seen youtube videos on 4 cylinder engine strip-downs.
Very easy to show who cold-starts an engine from upright or sidestand.
The wear cascades left to right due to oil splash, bore wear and the boxer engine would be the same, very minimal I agree but after 10,000 starts it would add up.

Probably the same reason the 'oil smoke on start up' from a side standing bike after 3 or 4 days just affecting where the oil sits.

I always push the start button when ready and sat on the bike so the lubrication goes to both cylinders together.

Like any good new RS owner learning the oddities of his bike, I came up with a highly engineered a solution to minimize said effect!20230328_205309 (002).jpg - Bild entfernt (keine Rechte)

Really!

I thought the phrase "Bmw brick" referred to their earlier 3 & 4 cylinder bikes with engines in their sides, is this the latest 5 cylinder model brick?

I just keep adding bricks when I think I need more power.

But if so, that implies that bikes sold in the Chinese market, with their OEM short sidestands, must have differently designed engines which don't suffer from this problem?

My 1986 K75 would smoke a bit after a long rest on the sidestand. I don't recall my 1984 airhead, 1999 Oilhead or current 2016 LC Boxer smoking, but I prefer using the centerstand. As others have noted in the past, a slight bit of material removal on the sidestand is the easiest solution. A little should go a long way.Sidestand MOD.png - Bild entfernt (keine Rechte)

I had a go at this. It was not particularly successful.

The springs are a bugger to release and twice that to put back.
The pivot pin (4) screws in from underneath, it has a T50 head.
You will have to file or grind a lot of material from the stand to make any difference. Sure you can make it swing further forward when its down, but because its near the bottom of the swing at that point, it takes a lot of forward swing to make much difference in the deployed height.
I reckon my bike needs it about 1cm higher when deployed and I couldn't get anywhere near that.
I gave up on the job and reassembled, I'm not expecting much improvement when I take the bike out.
