I've just finished a repair on my centre stand. I think about replacing it with the 4V version but they don't come up very often. The main reason for replacing the 2V with the 4V seems to be the issue with rusting out and collapsing.
This should never be an issue with mine as is has been treated internally with a good dose of LPS 3 and new end plugs. I did however wonder whether there is any difference on the ease of deployment between the 2V versus the 4V centre stands. I know a few members own both types of Brick so maybe they can answer my question.
Regards Martin.

I have both and also swapped my RT from the curved stand to a K1100 stand.......in my case the old 2v is much easier to get the bike on the stand.

I recently got a complete K1100 assembly to go on the K100RS which has been repaired by the previous owner after it broke and cost him a packet.

The 4V center stand is slightly shorter so it makes it a little easier to get a bike on the center stand.

Thanks guys confusion reigns again, one for 2V one for 4V ease of deployment. I also suppose the varying wheel sizes 17 versus 18 also factor in.
Regards Martin.

Hey Martin!
The 4V stand is much more reliable.
I kept the side stand from my 2V.
The clutch still works when I pull the clutch with my left hand.
Easy to do.
The best is you have a friend sit on the bike while you work on the bike.

Cheers

Thanks Chocolate but I don't need someone to sit on the bike. Years ago when I did the rear main seal I quickly bashed out a Brick Docking Station. It's a bit overkill but it was what I had on hand at the time. I use a strap to secure the bike to the uprights. I also have a home made lift ( hydraulic hospital bed) but I don't like using it unless I have someone to guide me on. I had a slight mishap and the tyre hit the wheel clamp and the Brick got tired and had a nap. 2V versus 4V centre stand ease of deployment?? 177381

I have one of these folding ladders I use for DIY. But it also is a work platform. Set up as a work platform it goes over the K, adjustable ratchet straps dropped down to the rear frame take the weight of the K off the rear and keep it upright. Can work totally alone and makes things like changing stand assembly or rear shock when you have a busted centre stand a cinch.

I have also been down to my local Honda dealer yesterday for new tyres......some new bikes were delivered in shipping crates. I asked what happens the crates [they are shipped from Japan in the crates], he pointed over to a pile of metal scrap in a corner.....now these are perfect for a K even. They bolt together and flat pack, the braces are all bolted in..........The bikes come fully assembled inside the crates with ratchet straps keeping them in place.

After the first couple of deployments of the repaired stand it got hit and miss whether I was going to get it up onto the centre stand. I found a Late K100 stand on Ebay and the guy was going to send pictures which failed to arrive. I then sent him an Email asking for condition of the bushes and got no answer, so decided to search elsewhere. I ended up with a K1100 one off the local BMW wrecker which I picked today.

I gave it a bit of a clean up and a coat of Rustoleum Canyon Black on the legs. The K1100 side stand had the auto retract when you take the weight off it. I wasn't real keen on that function so I did a bit of a swap between my original and put the clutch retract setup on. I used to have a slice of boat roller fitted to my side stand to get it at a better angle, which is now not needed. I will have to get used to the new stand but it is definitely easier.
Regards Martin.

Martin, I assume by auto retract when the weight comes off you mean via springs like some of the airhead models. The reason for my comment is that I have never seen one on a K1100 and wonder if the OEM K1100 side stand has been modified to achieve that type of action.

I modified the side stand on my R80G/S to not auto retract and then fitted an indicator light on the dash as a warning when the stand was down. Somehow, like many of us I survived the first 30 years of my riding life without any side stand intervention devices.

Cheers

Gaz you're right, there was a third spring that I assumed to be auto retract. I had a look and besides the spring it has a plate with a hook on it. At this stage I don't think I have all the pieces to make it work as clutch retract. I would be interested if anyone has pictures and an explanation of how it works. I did use the K75 clutch retract mechanism with the new stand but the pull required to retract the stand is a lot heavier, and would put more strain on the clutch cable.
Regards Martin.

Reading between the lines of post #5 in this thread, there seems to be clutch lever actuated retraction of the 2V side stand attached to Chocolate's K1100 center stand. I see what appears to be a retraction rod in the photo. Maybe Chocolate can shed some light on making this mechanism operate well for you.

Thanks Laitch I had a look at Chocolates mechanism and it is the K75 one the same as I'm now running. The K1100 mechanism substitutes the 75 plate with the rod for a plate with a hook and a rotary spring. From what I can see in a parts drawing there is another plate (missing) that is somehow activated by the clutch. I have greased all pivot points copiously with a mix of goanna oil and koala grease, however still a lot heavier than previous activation. If I can't find an answer today I'll start a separate post.
Regards Martin.

As a test I just fitted the rotary spring and hooked plate to my old stand. As the stand is deployed the rotary spring is put under tension. If I fit the rotary spring onto the K1100 stand with the K75 plate and rod it should help ease the burden on the cable. However it will have to wait until tomorrow as we are taking eldest daughter out on a shopping spree for her birthday. On one hand clothes shopping with two women or working on the Brick. BAlance
Regards Martin.
