Title: Disassembly - R65LS questions
Post by: Red_Hen on February 28, 2009, 11:06:33 AM
Greetings,

I only have the Haynes book so far and don't see what's holding the gas tank from coming off - same for the seat.  Someone drilled a hole to open the seat - obviously did not have the key - where is good resource for new locks & keys for forks, ignition, tank and seat?

Pulling tranny - it will need an o'haul.  I read removing the swingarm is easiest way to remove it.  Isn't there a special tool or socket I need to purchase to get into the swing arm hole to access the socket?

Is dual plugging a good suggestion for this bike?


Thanks much!

Ken in MN

Ken,
   At least you have one book. Sometimes an exploded diagram helps in seeing whats what. Have a look at this sticky on the top of the   BMW Technical Q&A, Primarily R65 section http://www.bmwr65.org/cgi-bin/yabb2/YaBB.pl?num=1217822327
you will find some helpful info there.
You'll first have to get the seat off and from the sounds of it the lock / latch has been buggered. There should be a button to the left of the lock that when depressed allows the seat to swing up on its hinges. you may want to remove the side cover and peek up into the lock area to see if some "customization" has been done to secure the seat. Photos will help us see what youre up aginst. Get the seat free and we'll take it from there. Others will chime in soon.

Photos really do help.  Also tell us the year because there are a few subtle differences.

You will need to make or buy a socket for the swingarm locknuts.  Rob posted a link to these a while ago...

as soon as it thaws out a little, I'll pull her out and snap some photos.
Is the transmission on this a 4 or 5 speed?  I think it's either an '81 or '82. Henna red with the white mag wheels.

The LS didn't come out until 1982.  There is a web page out there that has a VIN decoder that will tell you a bit more about your bike but I can't remember the URL offhand.  Maybe do a forum search?

Did you get it off ebay? Minnesota? Forest Lake? I was going to get that bike! He offered to me for $899 if I remember. My cousin lives in Stillwater and I was going to have him pick it up for me. Nice project, congratulations.  ;)

My '81 R65 came with the same "customized" seat latch and lock as yours! I scored a replacement lock box, the internals and a new lock and key from Re-Psycle BMW http://re-psycle.com/. They are in Ohio. Mark and Marco are good sources for used BMW bits. Expect to pay about 50% of list unless it's something made from Unobtainium.

Once the seat is open, you'll likely be able to see a wire "bail" with a short, heavy rubber hose on it. Roll this bail aft, disconnect the fuel line and pull the tank back -initially- then lift the front off its rubber pad mounts and pull it off up/forward. Really simple... with the seat open. Just don't drop that expensive fuel tank.

Check with Re-psycle for an ignition switch. Your're likely going to have to buy a new -as in $$$- fuel cap if you want a keyed cap. Start saving now. I bought a cap from them, sans key. Same goes for the fork lock. Unless you have a serious locksmith in your family, I see you carrying four different keys.

I have only one key for my '81 and that's the seat lock. No lock on the fuel cap, forks or ignition... that's kinda hidden. I often leave my empty "Uncle Mike's" pistol holster clipped on the bars. Curious types wonder, "Is he packin' heat?" Nobody has taken the holster, either! Well, this is Texas.

Suggest you spring for a Clymer manual to go with the Haynes. Both offer info not always covered in the other! Go figure. Also start tagging the many BMW tech resource sites on your compuKer as "favorites". Start with Snowbum's http://bmwmotorcycletech.info/ Disregard the racoon he wears on his head. He really does offer a lot of quality info. Plan on using up 2-3 days just wading through everything.

Forget the dual plug mod. You already have your hands full. Just get it running properly so you'll have a baseline to work from.

What does the holster fit?  I might borrow it if I see it...

4 keys??

I never lock my fuel cap because it can cause more problems than it is worth.

I never lock my forks, because I always forget to unlock them, and I dump the bike as soon as I leave the parking space.

I never lock my seat, because I never saw much point.   Maybe if I had some money in the tool box...

The small daily driver is either a Beretta .32 semiauto or perhaps the S&W Airweight .38 wheel gun, depending on my mood o' the day. The larger fits a 9 mike-mike Springfield XD. Others are either too long in the barrel or too bulky for easy concealment.

Yikes! Have you noticed he price of ammo has gone through the roof?

And has anyone else seen the Dallas, Texas, PD's effort to get some guns off the street? Turn in a gun and get a gift card worth $50.00 in groceries. How lame.

Weapons buy backs? My son's first tour in Iraq with the 1st Cav included a day providing security at a soccer stadium where the locals were turning in any weapon and/or ordnance they could scrounge up -rusted solid or not- in a buy back program. $100.00 USDollars in cash was the minimum payout! Zach watched Iraquis walk off with thousands of greenbacks for junk weapons... although a few might actually fire. He's now in Afghanistan for a year after being home for less than 90 days after fifteen months in the sandbox. World tour number four for this E-7.

And Obama speaks of "change"...  blah, blah, blah

Hi Ken,

My LS, like yours, only relied on the seat to hold the tank down.  Which was fine unless I went over a speed bump too quick.  There should be a clip that attaches to the tank at the top and hooks over the top frame tube.  In this linked diagram it is part 13:

http://www.realoem.com/bmw/showparts.do?model=0359&mospid=47852&btnr=16_0228&hg=16&fg=03

Prior to getting this clip I used a cable tie, and the cable tie did a better job, the clip as supplied from BMW seems a little loose.

I ordered new parts for my LS from Hammersley BMW (http://www.webparts.com/). I even purchased a new instrument panel facia, as mine was damaged.  They happily shipped to Australia so shipping to North American addresses should be OK. The only problem is their parts fiche prices are out of date so some parts may be a lot more expensive. They notified me of this via e-mail.

I have also ordered stuff from Motobins and Motorworks in the UK. One great buy was the R65 owners manual from Motorworks. I found this a great little resource for servicing info.

Hope this helps you,

All the best,
Paul

And make sure you have the two rubber pads (ors something like them) - items 2 and 3 in that diagram.  Over the years, the glue dries out, and they can fall off when the tank is removed, without you noticing.

Don't try to remove your tank over half-full.  It is very heavy.
Make sure you have a spot to set it down before you remove it.  And watch the petcock!

We use an old tire to put the tank on when it's off the bike.  It's sits down nicely and leaves room for the petcock in the middle.

Now that is a good idea!  [smiley=thumbup.gif]   Monte
