Newbie needs some help
« on: March 13, 2013, 07:01:59 PM »
I have a new to me 85 K100, 16k. I bought it last fall. I rode it this past Sat; ran great, but blew the 7.5 amp instrument fuse (#1 on the fuse box) after riding about 50 miles. Started it up tonight in the garage....ran fine, then started to puff some smoke from somewhere under the tank. The fuse blew again.
Any ideas where I might look to figure this out? I am no wrench......just looking for some guidance in case it is a common thing.
I hope that I can get it fixed without breaking the bank...the bike is much fun to ride! It is starting to make me nervous, though....
Thanks in advance for your help.

As you have seen smoke from the area underneath the tank, it would be a rather good place to
start looking for fried wires and connectors.....................

Check the the connectors for the clutch switch and the front brake switch...yellow wires at switch
side..........these you find under the tank, ...powered from fuse #1.

Update...It was the grip switch, along with some frayed lines. All is well now, I hope. I love this bike, but the age of it is making it a pain. It is probably better suited to someone who has wrenching expertise. It runs great...but I wonder how long I will keep discovering age/ neglect issues. Alternately fun/frustrating!

macman- i have an 85 K100 as well that i got last spring and am slowly rebuilding but.... when it passed inspection and i got it licensed i hit the road. I too love this bike after coming from a Kaw Concours and a 91 ST 1300. Both of those bikes are not as comfortable or as fun as the K has been. Unfortunatley i have to fix my tranny before it is road worthy again. If you love the bike and have any mechanical apptitude then dive right in and do the work. Great advice on this site and it is very easy to work on. Mine was VERY neglected but i am SLOWLY nursing it back to health. But it handles better than any of the other 12 bikes i have owned over the last 36 years. Lets trade some Pics?  :loopy:

Don't run those heated grips in the low setting. Guess it tends to fry the wires.

That might be you and you don't know it yet.

I acquired my K less than two years ago on Craigslist. Besides oil changes, I had never worked on a motorcycle in my life. A week later I rode it up to the local BMW service desk and asked the service manager what they could do to replace worn bits, etc. The service manager suggested that old K bikes were relatively easy to work on and encouraged me to get a repair guide and attempt the work myself.

I remember poking around on the bike in my driveway soon after, cautiously removing bits of the fairing, hesitantly unscrewing and screwing, and spending a lot of time on this and other K-bike forums. There's lots of good K-bike maintenance and repair info and help online. I took advice from the forums, tackled one thing at a time, and slowly became more comfortable working on the bike. I learned quickly that the K bikes were well designed and fairly easy to work on with a few simple tools.

For months I was scared to remove the top of the fairing or the fuel tank. Couldn't figure out where the air filter was. Total newbie. But after doing those things once I realized how simple they were. I am comfortable enough now to almost completely disassemble and reassemble the whole bike.

I recommend you dive in and ask questions as you go. You might be more capable than you think.

i totally agree with tim T. U just never know. And the satisfaction of a job well done and you know it was well done because U DID IT! Nothing like it and makes the rides more fun. Plus if u have problems on the road u will probably know how to fix it. My K Fuel pump was so gummed up it quit after 1 mile from the po house. After research i got a new Ford fuel pump and sock , installed it and it fired right up. Now if the tranny was that easy to do  :hmm: oh well.... another chance to dive right in and clean and spruce as i go. Yeah! '
Go FOR IT !

I think I have to agree with Tim. I am 48 years old. Never had a bike before this past summer. Ever. I think I am being generous when I say that 6 months ago I had the mechanical know-how of your average 9 year old. Seriously. I had never even changed the oil on a car, much less done anything on a motorcycle. So I have been a lurker here and on other boards. I bought a the Haynes manual. And I have cultivated a relationship with the previous owner, who is a cranky old bastich who goes by the handle of Ned37. Heck, when I trashed my right system case, I struck up a friendship with another member of this board who gave me advice, then called to talk me through what I could do to fix (what turned out to be unfixable) the damage.

In the last month I have: 1) changed a front tire; 2) replaced a snapped clutch cable; 3) changed the oil (twice - 1st time I did not take proper care of the o-ring and got a leak and I had to do the whole messy deal over again); 4) changed the gear and final drive oils; 5) destroyed a System Case, tried to repair, figured it was beyond hope, and replaced it when I found a screaming deal on-line; 6) changed my spark plugs; 7) snapped the plastic bolt (already bent) on my right battery cover and replaced that, 8) tracked down the same exact fuse issue (#1 7.5) due to frayed wires where that are exposed at the front fork.

At every step, I have felt (to some degree) intimidated, frustrated, inadequate and embarrassed. I just LOVE feeling not competent!  :loopy: BUT. I am also learning that even as a  raw geezer-noob, there is almost nothing on my beloved brick that I should not be able to learn how to do on my own. I have got to tell you, that is almost as liberating a feeling as riding 100 miles of twisty Arizona roads on a Sunday. Now I get to look forward to learning what tools I need (each time I do a fix, I get the next tool I don't have that applies). And my sense of connection with the Brick grows each time. Freedom and responsibility. Can't beat the combination. So don't give up, there are more of us in the same boat! Peace.

Macman,   I am far from a wrench but with a few exceptions I can do most of the work on my K with just the tools in the tool kit that came with the bike.   With a repair manual (one is on this site) the help of this forum, your local BMW chapter, IBMWR.ORG and the BMWMOA site there is enough information and knowledgeable people to help you through almost any project.  The big thing is taking your time.  If in doubt, take photos as you take it apart so you know how it goes back together.

As for the age of these bikes.  Sure, a newer one MAY need less repair but they cost a whole lot more.   Once you work out the kinks your K will treat you right anywhere you ride it.  FWIW I doubt you'll spend as much refreshing your ride as you would to buy a much younger ride. 
You can't help someone who doesn't want to hear the answer.
