So, I have the chance to pick up a project '85 K100RT w/ 29k original miles. The problem is the PO passed away and it hasn't run in 20 years. It was well kept when running and was in a garage the whole time.
My questions are:
The tires look pristine but they are 20 years old. Replace?
The tank is a mess. Varnish and black gunk (probably from the fuel pump dampener disintegrating) all over. How to clean this out?
My concern is fuel that has sat in the rest of the fuel system,injectors, etc. and the varnish that is probably there. How to deal with this?
Anything else I'm missing?
I figure at least $1500 in parts. I'll do the labor. I can probably get the bike for $1500.
Deal or no deal? :dunno2:

Tires are probably slick as cue balls if you rode on them. I'd remove the tank, take out the innards and try kerosine, gunk engine cleaner, whatever to clean it out. Check all the rubber bits for cracks, especially fuel lines. Brakes may be shot. New battery, fluids, I would offer $800.

Replace the fuel lines and have the injectors cleaned. This guy (http://www.mrinjector.us/) is good.
+1 on replacing the tires.
You might look at this post (http://www.motobrick.com/index.php/topic,624.msg1572.html#msg1572) and consider replacing some other rubber bits while you're at it.
I don't think you will have $1500 in parts to get it running unless I'm missing something.

All good ideas, thanks for the point outs. :2thumbup:

I'd replace virtually every piece of rubber that holds air, water, gas, or oil. Tubes, hoses, o-rings, bushings, the lot of it. Apart from the tires, that'll set you back less than $500, maybe closer to $300. Some clever person could probably make a few bucks by selling a labeled kit of these items all together.
Another +1 on injector cleaning at mrinjector, and the tires of course.
