Hi all, my first post, but not my first Beemer by any means. I haven't had an Airhead since my very first Beemer in 1990. Just purchased this on off eBay and took delivery yesterday. PO says everything works perfectly, but I noticed right away the hinge to raise the seat is gone and someone rigged a bolt to keep the seat secure: still stays on but to get to the storage tray underneath you have to unscrew the bolt and it's by no means easy to get the seat back on. It may be the hinge is no longer available, so, not the end of the world but...

My main issue is that the center stand has no way to engage without reaching down with your hand and pushing it to make contact with the ground. With my old '80 S, I seem to remember you could dismount and put the bike on the center stand with an arm that came out past the muffler. I could be mis-remembering, as I don't see that this "arm" is broken off the existing center stand. So my long-winded question is, does the stock center stand come with an arm that allows you to put the bike on the center stand, or do you have to engage it with your hand after you put the bike on the side stand?

The bike is an imported Canadian model, Kilometer tach/speedo and everything, with a gray color and blue frame, (I'll post a pic if anyone is interested), so could that be the reason for the funky center stand? Or maybe the bike has a center stand from another bike?

At any rate, if the PO writes in the ad "Everything works as it should..." would you give him a good review with these two discoveries upon delivery? I'd appreciate any body else's experience with their center stands. I really must stop buying motorcycle off eBay.

Welcome to the forum! If you

Welcome to the forum! If you can upload a picture of the seat/bolt, that would be good. I doubt you have the lift off seat kit as you have to actually unbolt something to get it off. There are some salvage yards around that might have some used parts off a beat up old seat. Airhead Salvage is one that comes to mind. But you might want to convert to the lift off seat type...I did the first year I had my /7 because the hard Wixom bags allowed the seat only to come up enough to barely get my hand under the seat...the Wixom bags don't come off that easily. Duane has info on his site about it:

Yes, the center stand should have a tang sticking out the side to help deploy it. The owners manual even shows the owner how to use it to first drop the stand and then stand on the larger foot pad to stabilize the stand while raising the bike. See this picture from the RealOEM fiche:

The tang is not for raising the bike, only lowering the stand. I suspect someone remove it for some reason...a new one can be fashioned and welded back on.

Also here's a picture of the tang on my /7 center stand:

Welcome pockomoth

Hi, Regarding the non pivoting seat , is just the two pivot pins that should be attached/welded to the subframe missing or is it the parts on the seat base itself that's missing ?. If it is the pins on the subframe that are missing , they are listed as a spare part.I feel your pain regarding some sellers on eBay , been down that road myself. You could always get hold of the seller and see if he can supply all of the parts required to repair the seat back to standard O.E trim, as this mod was not listed in the sellers description. eBay/PayPal are pretty good to deal with.

Thanks for your reply. The pins are missing, but more importantly the parts on the seat base are gone, seems like they've been ripped out and epoxyed over, then a plate attached to steady it on the subframe at the right height, and then the whole base pan painted black. It would require a lot of parts and maybe even a new base pan for the seat, as it looks like the whole thing just got ripped out somehow, probably someone pissed because you couldn't swing the seat up with the right saddlebag in place, one of the few poorly thought out designs on the bike.

I did ask the PO for spare parts, seems it came that way, just didn't mention it cause it didn't bother him, it's just he wrote in the ad "everything functions as it should," which to me means something very specific, to him it meant he could get underneath the seat. And the center stand worked, you just have to get down on your knees to get it to the ground, hey works as it should, right? He gave me $700 to make me go away, nice for him to do, but still felt dirty for me to give him a good ranking on eBay. No more bikes on eBay. I just never see S models in the Bay Area and when you do they're crazy expensive.

White people problems, right? Got a good business, I can afford to buy a bike or two (or three:), just the lack of honesty sometimes gets to me.

Thanks for listening. And the info. When I get my bike back out of the shop (did I mention he told me after the sale that the clutch cable needed adjusting i.e. the clutch had no more free play left, i.e. needs a new clutch?), I'll post a few pictures. It's a beauty, Canadian model 100S with silver paint and blue frame and wheels. Kilo speedo too. Now I won't know how fast I'm going!

Roscoe

It looks now like the tang broke off and someone welded the base flush with the rest so it disappears. Thanks for the picture, explained everything.

A broken-off center stand

A broken-off center stand tang on /6s and /7s is pretty common, Roscoe---I lived without one on my last /6 for several years. I found that when the bike is on its side stand, I could get my size 9-1/2 boot up over the main center stand leg and pull it down without the tang. You had to practice a bit, and know where to stick your foot, and you wouldn't want to leave the front of your boot or pants leg against the pipe/muffler for very long, but once you know what you're doing, it's a pretty quick deal. It might've been more problematic if I had had much bigger feet, and having the tang there to put the center stand down (not to lift the bike up!---that's probably how it got broken off) is certainly handier, but it wouldn't be a deal-breaker for me. It can be fixed without replacing the entire stand.

Your seat situation is annoying; you should be able to get into the under-seat storage areas on that bike without a bunch of gyration. On the other hand, it can be put back in order for the $700 you got back from PO, so be happy about putting/keeping another fine airhead on the better side of the boneyard fence.
