Title: How much maintenance
Post by: whosyurdaddy on May 05, 2017, 05:41:29 AM
  On the local Craigslist someone has a 92 K75S for sale with just 6K on the clock . Now I'm not looking to buy the bike but I was wondering about maintenance . Outside of the obvious fluid change and brake flush , what about spline service ? Going by the miles you don't need to do any service but going by the age you would think the service is called for . Just wondering how others would approach this situation .

A bike used as little as that one should have the hoses, fluids and all rubber replaced including, of course, the tires. Seals may have shrunk. Gaskets may have shrunk. Grease could have dried out. Oil has been forming acid in the crankcase. Coolant may have turned the coolant channels into fungal estuaries. Brake pistons could be seized. Condensation may have penetrated where it can affect electronics.

Much will depend on where and how it was stored. It'll need service.

Laitch good call on the rubber bits and gaskets , something I hadn't considered.

Water settling in the low points of the gas tank can corrode the aluminum, and the mileage may be suspect with malfunctioning speedometers/odometers pretty common.

Other than that, the outlook here for it is good. :giggles

What's the asking price?

Bricks need to be ridden, they don't like sitting. Electrical connectors seem to deteriorate from sitting. The rubber damper also disintegrates in the tank. A bike that has been ridden, even if it has higher mileage, more often than not turns out to be a better choice.

I bought my '93K75S a number of years and 30K miles ago with sparse maintenance records and a flashing ABS light.


It took about another $600 to replace all the fluids, tires, filters and have Tosi repair my ABS "brain" for a total of about $3000.


Seems a bit high for me knowing the cost of "zero-timing" the maintenance but I really like my K75S and want another :riding:

One year ago I bought a local 1994 K75s with 46,000 miles for $3800. I thought the price was a little bit high, but it was very well maintained, regularly ridden, had a Wilburs shock, better than OEM fork springs, heated grips, and was the first S-model I had seen in some time. I paid the $3800 and have put over 17,500 happy miles on it without any issue or regrets.

A 1992 with only 6,000 miles may be a crap shoot. If those crank journals haven't seen fresh oil in 24 years, they might be rusty. Actually, every part of that bike could be a crap shoot. Do you have pictures of it?

I guess I am an eternal mechanical optimist.  I agree that rubber bits can be perished and the fuel injectors will be gummed up solid, not to mention the fuel pump or corroded master cylinders.  On the other hand, wear items like splines, discs, brake pads, clutch, steering head bearings and valve clearances will be at original factory specs.

A bike with 6k on the clock would give me a lot of impetus to work a deal with the seller.  The price could be pretty high, but I haven't seen it.  I would try to work a deal based on being able to start the bike and see it running.  I'd bring a jump box, and some fresh fuel in case the tank was empty and some starting fluid. 

The results of trying to start would make for some good negotiating points for a better price.  If it starts and idles on the first try, I would think that $4k would be a decent price for an almost new bike.  On the other hand, if it won't start or idle, there would be some good negotiating points for a lower price along with any problems with the master cylinders.  Tires could be another negotiating point, but if they look new, the seller probably won't budge, despite the fact they are 24 year old death traps.

I wish that bike was close to me.
