coming out of very long term storage

[ksd]

I'm about to check out a 1987 k75s that had  less than  1000 miles on the clock before it was "drained of all fluids" and stored away. I guess my question would be, other than the obvious external rubber bits that will need to be replaced and assuming the bike was pickeled properly I'm wondering what the posibility is for the engine coming back to life without  a major tear down to replace main seals etc. that might have degraded over time. Anyone in this forum that has experience with reserecting a  K bike that has been stored over 25 yrs. I would appreciate your input. Thanks: KSD

Hi, I don't really have the experience you are asking for but I want to say "hello" and "congrats on your find!" 
I think I can speak for others and say we'd like to hear more about how that came about... grandpa's old bike?  C-List?  bought an old barn and there it sat in the corner? ....?

Yes, inquiring minds want to know!

And, I'd extend that to all rubber bits, or at least any that conduct or seal fluids.

Great bike and model.  Wow - all fluids were drained?

I restored a 85 K100RS which was sitting in an Iowa barn for perhaps eight years.  From memory here's what I did..

Get the Clymer Manual!!! :deal:

• Replaced all fluids, engine oil, trans oil, final drive oil, coolant, flushed brakes.
  Replaced fuel filter, rubber damper that the fuel pump rests in and the initial filter below the pump...also replaced the in tank hoses.
  Replaced Tires
  Replaced front fork oil
  Replaced radiator hoses
  Replaced battery
  Replaced brake lines with the braided SS lines available on the aftermarket
  Lubed the input and final drive splines

I also had a problem with the Sprag Clutch, which is known is malfunction if it gets the slightest bit dirty or corroded.  Separate post for that.

Good luck!  All of the above is perhaps a couple of days work if you have the parts.
