Title: Center stand-shortened
Post by: williamemack on November 21, 2008, 03:30:49 PM
Recently I saw an article about taking a small section out of the R65 center stand to make it easier to opoerate. Now that the riding season is behind me, I can't find the article in this or any other forum. Anybody else see it and can help me locate?

Thanks,

Will

Typically what makes the centerstand difficult to operate is it wearing down over time and getting shorter.

If your front tire is touching the ground when parked, it makes it hard to retract the stand.

To make mine work easier, I had steel plate welded to the bottom of the centerstand feet.  Back to like new!

Great Idea, Rob!

I need to do that too.

You guys must be mind readers! I signed on today to post an inquiry about a thread I remember seeing, but couldn't locate, about sagging center stands. Mine has gotten worse in the past few weeks; had to have help getting it off the stand twice in the past month. My leg length is marginal for the standard R65 seat height anyway; I've played with the choice between alternatives that each can have a negative consequence — finding a lower seat (comfort) or installing shocks 1/2" shorter (handling). Though I can reach the ground with both feet nearly flat, I can't get enough traction & leverage to lurch it off the stand if the pavement has the slightest up-grade. (Makes parking-space selection an adventure.  ::) )

My bike has a Brown side stand. I use it to park the bike when the engine is cold, but I've been reluctant to use the Brown after shutting down a hot engine. I read a cautionary posting (I think on the BMWMOA Airhead Forum) a few months ago that parking a hot airhead on the sidestand can cause oil to seep into the left jug past the rings thus (1) over the short term, causing the characteristic airhead white smoke cloud when restarting, and (2) over time, possibly contributing to premature carbon buildup in the left-side head. Anyone have any thoughts about this?

Thanks for posting the photo, Rob. This gives me something to show my airhead-owning colleague (R90/6) who runs an auto repair shop. He thinks he might be able to do the work in his shop. I had read about this fix, but I had trouble visualizing the shape of the weld. I think having the shop skills many of you guys have might not be a requirement for owning an airhead, but it certainly helps.

I haven't yet removed the center stand to see if inadequate lubrication of the mounting bolt(s) by the PO has caused the mounting hole(s) in the frame to become elongated. I understand that a different fix is required in that case. Any opinions, repair techniques, etc?

Guess my time will be occupied during the winter. (I'll be physically able to ride safely just in time to stare longingly at the bike in the garage for a about 3 months.  :( )

I too would like to leanr about the frame hole elongation issue. I have the plates welded to the bottom of my stand legs and both my wheels touch the ground when on the centerstand and I'm wondering if the holes are the cause.  
Title: Re: Center stand-shortened
Post by: Rob Valdez 79 R65 on November 22, 2008, 02:17:20 PM
Unfortunately, about the only way to check for hole elongation, is to remove the stand from the frame.

I have only heard of this happening - last time I checked, mine were still round.

My 1981 R65 is also a real chore to dead lift onto the center stand. At home, I roll the rear tire onto a small piece of 3/4-inch plywood and the center stand issue goes away. I got too many strange looks when I would wear the plywood on a string around my neck while out riding so I quit that.

The '83 R65 is a whole different kettle of fish. Different design stand and no issue getting the bike up and on.

Could start a trend..

Monte, I tried the plywood under the rear wheel trick , except I used 1" instead and it sure worked slick. Is this not similar to shortening the center stand by about 1/2 inch? My holes are not elongated, the stops are not worn, and the front wheel is about 1-1/2" off the ground. It strikes me that the lifting problem is caused by the angle of the stand on the pavement before lift and the amount of lift. Isn't it all about geometry? Shorter stand should cure both. Can you show us a picture of the 83 stand relative to the 81 without your having to remove the stands?

From montmil: << The '83 R65 is a whole different kettle of fish. Different design stand and no issue getting the bike up and on. >>

Hmmm. Anyone know if it's possible to hack an '83 center stand to fit a '79-'82 R65 frame?


 Also from montmil:  <<I got too many strange looks when I would wear the plywood on a string around my neck while out riding so I quit that. >>

You could explain that you're an orthodox [whatever faith], and the plywood is a prayer talisman.  Decorate it with some runes, etc.   ;)

The plywood idea is great! Perhaps anyone with side cases could avoid the fashion issue by putting the plywood in one of the cases. (It would permit a slightly larger piece of plywood, also.)

I agree with Will on this one. I think the stand could be a little shorter and the geometry is not quite right. I've had severel bikes Triumphs and Japanese that had easier centre stands.

How to put it right though ?

What I have seen somewhere on the internet is the frame stops and angled tops of the stand legs built up with weld. This prevented the stand going too far over centre from vertical. It was claimed that the bike was easier to roll off the stand as you did not have to lift it up so much. There must be a trade off here between stability and ease of use. I could live with a little less stability.

Can't find that link but here's a good one on stand issues in general.

Here's the link I was originally looking for.

Scroll down the page almost half way to find the bit on centre stands.  Clicking on the pictures will open them up full size.

Is this not similar to shortening the center stand by about 1/2 inch?   Makes sense to me, Williemack, but I don't want to go first. You want to be the test pilot maybe?  "It strikes me that the lifting problem is caused by the angle of the stand on the pavement before lift and the amount of lift. Isn't it all about geometry?'  Keep talking. I like what you're saying. Anybody saying "nay" about this thought train?

"Can you show us a picture of the 83 stand relative to the 81 without your having to remove the stands?"   I've got seven days off over Thanksgiving -No free time wise cracks, Cousin Ed- so I'll get some snaps for comparison. The '83 has a nice 'foot tab' to assist with getting the scooter up on the center stand. Me likey mucho.

BMW made a kit to replace the early stands with the better 82 up version, the kit is no longer made, but BOBS BMW told me all the parts are available separately, about 175.00.  Monte , thats a pretty white 65!

I  took the opposite approach with the dearly departed "Blue', my '84 R65.
Instead of trying to keep the front wheel in the air, I installed a Reynolds Ride-Off centerstand, which worked like a charm, was a breeze to operate, and kept everything very stable and "on the level". Mine was chrome, but here's a pic of a black one.

(https://bmwr65.org/smf/proxy.php?request=http%3A%2F%2Fi146.photobucket.com%2Falbums%2Fr261%2Fsteve2371%2Fonlineposting%2Freynolds.jpg&hash=f53ae9c3b25f3b0b3aa8aa44d13888f1ef3fc6d4)

On the occasions I needed to get a wheel off the ground, which were few and far between, I'd put the stand itself down on a piece of 1x12" board and achieve the "stock" result.
I think I paid about $100 for the one I bought new on Ebay, and have seen used ones for less... [smiley=thumbsup.gif]

Monte,...  Talk about "Accessorizing" your riding look!

 ;D

But it really does need some "Runes" or ancient symbols on your amulet.

The Peace symbol was the greeting I remember from my earlier riding days.  Now it seems to be replaced with pointing your left hand down or to the center of the road (?).  When did it change?

What helmet are you wearing in the picture.  I'm still pondering an upgrade that will fit my skinny head with my eyeglasses.

Let's see more of the white R65.

I had actually added some penciled tire tread designs on the amulet  but they didn't show up.

Yea, the latest "biker wave" as explained to me, is left hand down with two fingers extended. The two fingers imply "keep the two wheels on the road" or similar.

I get the two-fingered salute from a local police motorcycle officer as I pass him on his... Euro oil-head BMW. Very sharp looking and so much nicer than the city's H-D tractors. He says he really likes it. It's a test vehicle for possible department bike replacement.

Myt helmet is a Fulmer Modus. Works quite well with my specs and hearing aids! Results of my misspent youth.

Broke down on Tuesday and bought a used Reynolds from Duncan's Beemers and have test fitted it. Boy, it that nice. I've got to make a few tweaks at the welders before repaint and final assembly. mostly to make it work better with the Brown sidestand. Going to add about 1/4 inch steel to contact pads and that will just barely allow the front wheel to spin thus making it easier to check tire pressure. Now I have to find another winter project to keep me out of trouble.

NCSteve, The Reynolds that I recently bought, looks exactly like the one you pictured. The problem is that my OEM springs don't work on it as the hook at the stand hooks 90 degrees to what is required. I haven't been able to find suitable springs and I don't dare try to modify the springs I have. Assuming your stand looks like the one pictured,what do you use for springs or did you modify the attachment hook at the stand?

Thanks,

Will
