I Bought A Cheap BMW K75S That Has Sat For Ten Years!! Will It Run??

[@mokomoko2489]

I am a Japanese company employee who used to own a K75S. The engine sound is the same as it was back then, and it brought back a lot of memories. I still can't forget it as a friend from my trip to Hokkaido. Thank you for the wonderful video",arigato"😎

@@SusanWillan I think it's a K75S because it has a half cowl, but is that wrong? The one I own is a red early model, and the one in the video is probably a later model with ABS. I'm not sure about the difference in the tires.🤔

K75 was my first bmw. That thing could take a person in great comfort

[@harrothepilot]

Nice old bike Tom. I have a ‘93 model with about 20,000 miles. The ABS light stays on from engine start, till you are doing about 10 - 12 mph. The red light in the centre of the cluster stays on till you have operated both front and rear brake at least once, then extinguishes. This happens every time you switch ignition on. The ABS is pretty ineffectual, sort of similar to the old twin spot Brembo callipers. They will smoke a bit, particularly if you park em on the side stand. Oil gets past the rings when it’s on the side stand. Check your coolant and make sure it’s 33% green antifreeze type mix. Rad fan is piss poor and prone to failure ( brush holder assembly melts and fails ). Easy to substitute an aftermarket car one. Rear drive splines prone to failure if not kept lubed. Easy job to do at each rear tyre replacement. I use a high moly content white paste made by Castrol. It sticks to the splines like baby poo to a blanket. Do the clutch splines with the same paste. They are a bit more time consuming though, like about 10 hrs all told from go to whoa., taking your time. The clutch lever will be the tell tale, with a rough/jerky take up being the giveaway that it’s time to be done. If it’s smooth and progressive, it’s probably fine. Supposedly, on a racetrack, they will run to about 125mph. Mine gives about 180-190 miles before the manic whirring of the fuel pump and a distinct lack of forward motion combine to let you know you have just run out of fuel. Surprisingly, two up doesn’t make a lot of difference to the economy. Compared to my ZRX1200S Kawa, it feels like it’s going backward when I wind on the throttle. You cannot beat the absolute smoothness of the 740cc triple though, silky smooth. There are rumours of one here in Australia that’s done over 500,000 miles, but that is purely hearsay of course. A good battery kept charged, will help to keep sticking starter relay problems at bay. This can also destroy the starter if you don’t catch it in time if it does stick All in all, a very long lived motorcycle. Best regards.

[@TomsTinkeringandAdventures]

Thank you for the detailed information. I eventually figured out most of that stuff. I’m enjoying the bike, really smooth.

[@jamesflannery5303]

I also have a 93 bmw k75s with abs and the red warning dash on but once I start riding, it starts flashing, also the oil temp light seems to be on all the time. I don't have an owners manual and would really appreciate if you could help diagnose reason y they would be on.

[@anonperson7386]

Fine bike, sir. Let it be known that where the final drive input shaft meets the drive staft is the weakest point and needs regular (10k miles) cleaning and lube w/high moly content lube. Check it out if you haven't, yet. Easy to access. Cheerio.

[@TomsTinkeringandAdventures]

The bike needs new tires and the shaft drive lube is on the agenda when that happens. Thank you!

[@GWAYGWAY1]

It fires the pump when the starter button is pushed, you can prime the system by repeatedly pushing the button and you hear the pump hum. If it has been standing it makes it easier to start. Also the ‘choke’ is not a choke but a tickover raiser it only opens the injectors a bit. The filter would be blocked after that time. The red light need both brakes to be used and checks the rear brake bulb. They all smoke when left on the side stand as the oil goes left and passed the valve guides into the exhaust pipes. I have had my K100 since 1984 and first one sold in the UK.

[@sprezzatura8755]

This is one of the best motorcycles of all time. Easy 200,000 Mile motorcycle. BMW realized it made no financial sense to make a bike that lasted pretty much indefinitely. Financialization wins. But I'm seeing signs of a backlash. Many people want simple machines they can do their own work on. Like this brick 💘

Plus it had a lot of tech that bikes didn’t have at the time. Smooth engine, good transmission, just a nice overall machine.

Congrats on getting this BMW going. I owned this model about 20 years ago and loved it. At my height, 5 feet 7 inches, it was easy to set both feet on the ground! I currently ride a '94 R1100RS with only 22,000 miles on it. It runs like the day I bought it. Like any bike, you have to maintain it regularly, especially the aging rubber hoses. Enjoy your bike.

[@TomsTinkeringandAdventures]

Just like any bike, they require basic maintenance but these seem to hold up pretty well. It's a nice smooth bike, nothing exhilarating but it's plenty quick. Your BMW should last a long time, get out and ride the heck out of it.

[@ThisDudeSomewhere]

I guess you know by now, but if you tap both brakes, the ABS system will do a self check and if ABS is good, the light will go out. Also, K bikes are well known to burn oil if you park it on the side stand. You should use the center stand if at all possible.

[@TomsTinkeringandAdventures]

I didn’t know that, thought that it only went out after riding it past 10 mph or whatever. Thanks!

[@MrBestvirginia]

ABS is kinda pulsating? But that's what an ABS unit (anti blocking system) is designed to do. Increased braking distance by releasing the brake then re-applying it Also, good advice for the older ABS systems out there: it is good practice for each ride to get the ABS to kick in at least once (one time for back, one time for front) so the internals on those old units dont seize up. Works good on gravel roads

[@TomsTinkeringandAdventures]

Yes, it's supposed to do that (pulse the brakes) but it felt weird compared to other ABS motorcycles I've ridden. I suppose this was one of the earliest versions offered on a motorcycle, so it's likely normal. I was more surprised that it still worked!

[@bryanwilkinson6859]

Very good choice ! the only issues on mine were a weeping seal on the combined water and oil pump (fixed with seal sweller pending pump replacement ) and one electrolytic capacitor on the fuel injection computer- you have to carefully look for a 40 microfarad one on the circuit board , observe polarity and de-solder it. then Solder in a new one. this job best done in sunlight.

[@chrisjohnson4165]

I've had 3 K75s, my current one is the S model like this one. I love these bikes! Yours has RT bars fitted, and it looks like the cables need tidying up a bit. You'll find these bikes really grow on you. They were the most advanced bikes of their day, and although they seem underpowered, you'll find a K75RT will cover the miles quicker than a sports bike over long distances, and in comfort. When I had a K75RT, riding at 100 plus, sports bikes would join me and then drop back, probably due to neck ache. Well done on your purchase! BTW, do remember to grease the rear splines with moly grease, and change the gearbox and final drive oil to synthetic. You'll find that a YSS shock (cheap and cheerful) will transform the rear end. Oh, and junk the ABS, it's 15 kilos of ugly fat. Also, you'll get quite a big power increase by fitting EV14 injectors.

Cool beans. I was worried about your injectors there with all that junk in the tank. Friend here in Germany has an earlier K75 and his tank is plastic and has a hole, so guess the metal tank is a better bet now after 35 years. I used to have the 1000 cc K100RS (1988) and I believe it is still running to this day... Now I Want one again. My ABS failed-out quite frequently leaving me with normal brakes and a flashing light on the clocks until I worked out the error can be cleared out by holding down the ABS switch, then turning the key to ON, keeping ABS switch held down, then after 20 seconds turn key to OFF. It should then be operational again. You got the red warning light on dash until the brake light circuits were tested for continuity..

[@indy2867]

This is an inline three laying on its side. When it's on the side stand, the cylinders are below the crank shaft, and oil drains into the combustion chamber. If it sat for ten years it's likely to have a bunch of sludge up there. I would bet the bike doesn't need a top end rebuild at all, just get it going and burn a tank of gas through it on the freeway. That should cook off the oil in the heads.

Yeah, most bikes have the pump in the tank but it’s usually a complete panel that gets removed. These were probably one of the earliest versions of EFI on a motorcycle, so I give them a little bit of leeway.

[@AnalogDude_]

@@TomsTinkeringandAdventures yeah, the k100 was in '82 and had fuel injection. i understood the K100 used the fuel injection of a 3 series car and the first motor cycle with ABS.

[@JongJande]

The pain in the ass is caused by the ethanol that is in the gasoline nowadays. Has nothing to do with BMW. The problem is that ethanol attracts water that is in the air above the gasoline. When water comes in contact with the ethanol micro organisms flourish and excrete certain acids that demolish all rubber parts and corrodes steel parts. The fuel pump can be dismantled and cleaned by folding back the alu container. This same ethanol problems are well known with cars that have been in winter storage. Best is to use the much more expensive non-ethanol gasoline. Oil companies play deaf ....
