I have a '94 K75 that hasn't been started or ridden in 4 years. Due to knee surgery and variety of other reasons, I just lost interest in riding. I thought I'd get back into it, but it hasn't happened, so I've decided to finally put the bike up for sale. Before I do that, I need advice on what preparation should be done to insure the bike can be safely started and ridden. I regret that I haven't done anything to maintain the bike in the past 4 years, but it has been kept covered and parked under a carport, in the Seattle, WA area. We rarely see freezing temps, and the bike has always remained dry. Both tires have plenty of tread, and don't show any signs of rot. FWIW, the bike has always been mechanically sound and reliable.
I presume I need to replace the battery and oil. Would the fuel injection system, coolant system, or brake fluid need attention before starting the bike up? If I were to take this to a BMW dealer for this pre-sale preparation work, what would it likely cost?
BTW, the bike has 23,800 miles on it. I'd be selling it with a set of hard BMW luggage bags, KG tank bag, heated grips, windshield and storage cover. I believe this is the base model K75 (no sport features, fairing or ABS). Any clue on an appropriate asking price for this?
Any advice would be greatly appreciated. Thanks in advance for your time.
Sounds like a sweet little ride for someone with that low mileage.
Firstly, how long have the tyres been on it? I know you said that they have plenty of tread but given the mileage on the bike they are likely to be quite old and the rubber and construction could fail if not replaced.
Secondly Fuel. When you switch her on listen for the fuel pump to come on as it has possibly shit itself. If there is no sound when you switch on the power you may need to replace the fuel pump
There us a rubber covering on the fuel pump that may have disintegrated and is possibly laying in the tank and could block the fuel filter pick up.
Drain the tank, you can get at the fuel filter through the filler cap and its easy to replace then fill her up with fresh fuel.
The injectors are likely to be very sticky and it is very likely to run like a pig when you do start it.
To avoid an expensive injector reco, they often come good once you have run a couple of tanks of fuel through them so if possible try that first. Take her for a ride somewhere where you are not going to be under pressure from traffic and just keep winding her up and down the rev range pushing fuel through the injectors. It might come good.
Thirdly you might find the oil seal in the water pump has failed.
There is a drip hole in the under side of the water pump so after it has been running for a while check for an oil leak there. A seal kit can be purchased.
Finally check the fork seals. After it has been ridden check the fork tubes and seals for leakage.
These things are typical of an early K that has been dormant for some time but you may experience none of them.
Good luck and keep us informed on the project.
