Title: Centre stands
Post by: ukzknos on June 16, 2009, 11:09:31 AM
I know stands, both prop and centre, are not a strong point of the R65 but does anyone have a view where the bike should sit in relation to the angle of the centre stand to bike/horizontal?
I think my bike goes past the point that it should and it's a bugger to take of the stand on an incline.
Not a good explanation but pics below to illustrate.

It looks like yours either has wear on the frame lugs or more likely the contact area on the stand that bears against the lugs.  It could also be worn out pivot bushings.  I remember when I took the Reynolds stand off my '81 R100 the first time the bushings came out in pieces...

If it is stand wear the normal route of repair is to build up the worn area with weld and grind to shape.

Yours has about the same angle as mine does. As Justin and others are probably tired of reading, I've had center stand problems since buying my bike.

I hope that situation will change soon, for I just bought a "retro kit", or rather its individual components, from Bob's. In 1983 (or was it '82—mine is an '81, and I forget the year of change) BMW redesigned the center stand. Supposedly the redesigned stand will fit the earlier models and make the bike easier to park and go. The redesigned stand is slightly shorter than the earlier one, causing the angle when deployed to be nearer vertical. Also, BMW redesigned the shape of the "don't step on me" tang and provided a knurled area on the rear of the left leg of the stand, where the rider is supposed to apply foot pressure when pulling the bike onto the stand.

Looking at your photo, I can see that the stand on your bike is the older design, so it might be cost-effective to replace it with a Reynolds or the later BMW design (depending on the cost of welding and grinding new contact areas and lugs on your present stand).

I hope to install the new stand within the next week or two. Stay tuned for a report on how it works.

My '81 R65's centerstand is like Steve's... just not worn out, yet.

The '83's center stand is as described by Altriter. The difference in parking the bike/s is like night and day. The '83 is cake, up and down.

Someday, maybe, I'll pull the '81 center stand and chop about 0.75 inch out of the legs. Even without the knurled step pad, the mod will improve parking ops. The chore getting to the stand might be holding me off.

My 1983's stand is not as far forward as yours and my front tire is off the ground about an inch and a half.
It is easy up easy down.

Here’s two shots I just grabbed of my ’84 (22,000 miles) on its center stand.  It rolls on and off relatively easily.  The front wheel never is “freewheel spinning” clear even when stood on a very flat surface.  My driveway has a slight dip in it.  If I set the ‘bike with the stand in the middle of the dip the front wheel has just enough weight still on it to make me uncomfortable about the ‘bike’s stability.  Mark

"After" is definitely looking closer to normal! "Before" is looking about what one gets with the Reynolds "Ride off" stands as far as wheel elevation goes.  On my 82 LS with the stock stand the front wheel is around 2.5 inches or so off the cement floor in the garage.

You've been busy, Steve!

The new center stand is muy bueno. Far less chance of a hernia, too. [smiley=thumbsup.gif]

I notice a few additions to your bike: the hand guards and trunk, plus the missing pannier frame. What else have you been up too? You have a sharp looking R65.

Yup.

I've still got the pannier frames, but the panniers themselves are in such bad condition I decided not to use them (cracked, locks not working, seals missing and the one was bolted to the frame as the mounting catch is broken). I made a simple frame for the case and took the tailpiece of the seat so I could mount the box as far forward as possible and still open the seat which I had recovered.

Hand guards came off my Honda 200 CTX (like an XR200) and I also changed the tappet covers around so the engine doesn't look like it points up!

Pushrod and fork seals are also done and the next step is to make a screen & get the light sorted.

I have had concern about my centre stand condition and it is great to have this thread....

My front tire is 1" off the ground so maybe not too much a concern yet.  

The movement of the stand is stiff.

The foot tang had broken off in its past life so I bought another on ebay.  It has the tang, but the wear looks even greater - the pics were taken so that this did not show  >:(

To repair and grease the bearing, the exhaust must come off.  I have browsed for the exhaust tool.  Does anyone know a good source?  Not sure if all tools in this regard are the same.

R65_Mark - what brand flyscreen do you have?

I have one of these Vario screens and I can highly recommend one.
Previously riding the highway at 70mph was hard work but now I could sit there all day at that speed.
They are German made so not sure they are available over the pond?

For aesthetic reasons though I'm working on a project to replace this with a R90/100 'S' fairing.

Best price I found for the exhaust nut wrench was from San Jose BMW. http://www.sjbmw.com/ It won't be the prettiest tool in your box but it gets the job done.

Hint: If the exhaust nuts don't want to come off without using a multi-directional inertial transfer device, stop right there! My personal experience, like a few others, is that you can do serious damage to the cylinder head's threaded exhaust stud. Think big $$$ damage.

I cut off the bad nut and used a small file to dress a few damaged threads on the head stud. Use an anti-seize paste on the threads during reinstall. And luck to you getting that freakin' exhaust system off. Grrr

Here's my exhaust nut "Fugowie War Club". It hangs on the wall and visitors are like[smiley=huh.gif].   Monte

UKZKNOS -

Thanks for the link.  I like the MRA CUSTOMSHIELD.  Shipping cost may be an issue if they do  indeed ship.  I think these are similar to what National Cycle offers here...  

Montmil -

Thanks for the link. The PO had installed new exhaust nuts and applied a copper based grease when installing.  

I wanted to located a wrench also to be able to loosen the nut every year and apply that anti-seize compound.   :)

For what it is worth, from day one to today every time it is on the center stand (on level ground), the front tire on mine is about 3/4 of an inch off of the ground.  It makes for a stable center stand, although it takes a good heave to get it on the stand.

I just tried searching on that site & couldn't find anything to do with airhead tools. Tried a word search with no luck. Couldn't search by bike model, either, or under "parts." Has SJBMW dropped airheads from the bikes they support and service?

Looks like I'm going to need the exhaust nut wrench to replace my center stand, and sooner rather than later.

Thanks, Monte. I learned later that the guy who's going to be mentoring me through all this has the wrench in question, so the heat's off for the moment. Nonetheless, I think I'll check it out, just in case.
