On my introductory post (that got a little out of hand for an introduction:) ) I spoke of the new to me '85 K100 w/an EML sidecar.
The poor 'ol girl has not been run since '09.

After getting the fuel pump working, my introductory ride lasted only about a mile before it died and would not restart.  
Turned out to be no spark & no fuel.  Schmitt.

Removed the fuel pump first, and there was a lot of crud inside the nylon strainer.   Cleaned everything up again, and hooked the pump to a battery.   It spit fuel across the garage, and started to work again!   good news.

Now on to the spark issue....Many hours spent on here researching, and after cleaning everything under the tank well with deoxIT, including all grounds, it's sparking again!  


I found a few more things that need attention:
No temperature guage or fuel guage on this scooter.  Hmmmm, I can live without the fuel guage, but feel the temp guage is important.  However the previous owner put 271,000 miles on it without one I guess.  Any thoughts from fellow inmates?   


The electric fan also in inoperable.  Very hard to turn at first, but loosened up after some fiddeling.  there was no satisfaction upon hooking 12v. directly to the fan plug though....

Thanks to everyone here on the forum, as reading through the posts on different problems has been of great help!!  

I'm going to install the tank again tomorrow, and hopefully can go for a ride before wading into the rest of the problems.

Those fans are a very poorly made piece of garbage. one needs to be very vigilant to keep them running as they don't start up automaticly very often. What several here have done is to make a fan override switch and as well as turning the fan on when it's very hot you can give it a short run each time you're out on the bike and so be reasonably sure it remains in working order.

Hi Ken,
the lack of temp gauge is no problem, if it overheats your goolies will get boiled by hot water from the front of the seat area. (yes, I know this personally) and there is a really good tutorial somewhere in the "How to" section I think on cleaning up the fan. Needs the radiator off though, so a bit of a task to get to. Generally if you are moving, the temp stays under control all else equal.

Thanks for the replies all!  

I got to put about 100 miles on it Sunday, and feel a lot better about it.  I'm getting used to the steering and feel of having the sidecar on there.
It reminds me of driving an old 50's Volkswagen in that you kind of ignore the roaming around in your lane, and just keep it pointed generally in the direction you want to go, letting it wander on and off the existing tracks in the road surface.   
The electric fan even works now after cleaning everything~Override switch sounds like a great idea!
Transmission seems a little noisy to me, and it is hard to get to downshift after coming to a stop.  POssibly just that it is different than the R1100RS that I'm used to riding.  It just occured to me that possibly a spline lube might be in order too.


The German Shepherd loves the sidecar, but I've got to figure out how to make one of the windows open.  The wife even likes it!!

The first tank of fuel returned almost 28 miles per gallon.   I was expecting a little more, but it is geared pretty low, and pulling quite a bit of weight not to mention the extra wind resistance.

It shouldn't really wander about that much.  Mine used to till I added a poofteenth (official Aussie measurement unit, similar to a smidgin) more toe-in to the sidecar.  In my case ( it depends on your sidecar mounting method) i achieved it by addin a 1mm shim to the rear mounting to my sidecar chassis.  it doesn't wander at all anymore, tracks straight and true and it doesn't wear any tyres excessively either (too much toe-in will wear the sidecar tyre prematurely). 

It's a black art though, of that there is no doubt.
