New to K100, with project

[Laitch]

. . . while it looks completely hard and crystalized for the most part it is a soft goo.  My plan was to scrap out what I can see, vacuum and rinse the rest, then flush out the system best as possible when I get the pump back on.

It looks like oatmeal to me but there's stuff that is unseen too.

I'd want to get as much of that stuff out of the engine as possible and not run it through a rebuilt or new pump assembly. If by rinse you mean using water-pressure from a hose inserted into one of the passages to blow the debris out of there, that seems like a good plan. I'd want more pressure than the average urban water system supplies but you've got to work with what you've got. I'd alternate directions of the flow until satisfied that I'd done the best I could.

A coolant system flushing compound should be used a couple of times when the engine is ready to run. Follow these instructions.

The similarity with my bike/situation are uncanny.  After you clean as much as possible from the cooling system, then run it and use a flush product.  200 degree water and flushing agents will do wonders.  My bike runs "cool" now.  Don't worry about the budget...I am in the same boat :dunno.  My 20,000mi, always stored inside $2500 cherry turned into an extended European vacation. BUT, at the end I have a beautiful motorcycle, and can continue to make memories.  It is a hobby after all .  I found these people (with this site), after I had underwritten the local BMW dealer :hehehe, http://www.euromotoelectrics.com/category-s/753.htm.

I lost sleep know that the goo may turn hard since I opened it up, so I got up and flushed it out a bit.
Then when I got home from work I thoroughly flushed it, all directions, push with water, suck with shop vac, push with blower etc.  Its as clean as a whistle, thanks for the flush/coolant link, very helpful, once I run it I will also follow that procedure and flush with a cleaner while hot, great article!

My list of "must do's" continues to grow as I look on the forum, but like Jackgeiger I'm looking at it as a hobby rather than a roi.  I ordered some parts yesterday from my local bmw dealer, Ouch! (Thinking I'd have them the next day). But their a week out so that help pace me and address items that I may have otherwise overlooked.

It's Aaaaalive!
I'm about $800.00 in parts into it at this point.
Fuel pump, lines, injectors etc $450.00
Odessy Battery $100
Water pump parts +misc gaskets and lines $180.00
Gear, trans, oil, brake fluids $60.00

Took it for a short ride (not licensed) runs great, shifts perfect.

Purrs like a kitten.
 
Thanks for everyone's help, I really couldn't have done it without this forum and everybody's help!

Now for the fun stuff!!!!  Fan over-ride switch , led lights, moly in tranny and final drive, auxiliary/driving lights, elevation switch, etc. (so you can take those blank switches out of your dash ).

Beautiful bike.......is that original miles? You have done well, ride & enjoy, you can get those maintenance items done in the winter. :2thumbup:

Man, she looks damn near brand new! Sweet ride. Two other things I might throw in....check your steering head bearings for any notchiness or roughness. That grease could be long since dried out. Grease your kick stand and center stand....zerks instead of the usual grease gun ends. And if you have any electrical connectors apart don't be afraid to use DeOxit spray on those. They are likely corrosion free but you won't know until you pull them apart. Good preventive maintenance. Gryphon is dead-on, though. Follow his instructions, and those of others here, and you will have a lot of riding out of that bike.
As for tires....don't even think about running those ones. For what you guys can buy rubber for in the States!! Get new stuff asap and be safe!

Thanks!  Yes it has just under 22,000 miles on the clock, my neighbor bought it in 1995 with a little over 20k miles, the water pump went out in 2001 and he never put it on the road again.
The steering bearings did settle into the races and should be changed for smoother steering, I cleaned some of the electrical but it appears to need a new flasher, everything lights just doesn't flash, and it could use paint as the fairing parts were moved around in boxes for years and got scratched up.
Other than that it's pretty clean, and runs great!   
Went to the BMW motorcycle dealer bbq today, very tempted to ride it up there but as you mentioned the tires make me a little nervous so they will be replaced before it hits the open road.

Thanks, Mike
