I have a 1976 R90/6 and it’s recently had some strange issues with the odometer. The speedometer works just fine, but recently I looked down at the odometer and it wasn’t turning. Even stranger,

Its a increídible story, I think Lutz adds a bit of show, anyhow, he was a Genius as well as Muth. Thank you very much Mac. Tito Alberto Ayulo Kelly calapanizo@... 649077663

Article about Bob Lutz and Hans Muth: https://advrider.com/bmws-r-90-s/ I thought I had sent this to the R90sWorldnet......maybe not. Mac Kirkpatrick Glenmoore, PA "After all, what is adventure, but

Same with mine, Martin- If folks are still on original caliper pistons after 45 years, chances are there's some corrosion, chances are the pistons are dragging while trying to retract. Best- George

When mine did this, I had corroded pistons. I rebuilt the calipers with pistons from Bench Mark Works.They were half the price of OEM and have performed flawlessly. FYI. Thanks, Vech!

Make sure the the master cylinder is not mounted too far rearward and the arm isn’t hitting on the tank. It happened to me. Just take the tank off and recheck for brake drag. Jerry Hale

I was taught from an early age to get the vehicle moving to speed the warm-up process.? Having said that, I also learned to ride/drive gently? until the coolant (if applicable), and more

Mac, That is the truth. Mine needs the choke to start, but does not want anything to do with it once it is running. When it is cold, I can leave it on for 20-30 sec. When it is warm out (engine cold)

I start me R90S with the choke (enrichener) full on, make sure the oil & charging lights are off, take the bike off the center stand and ride off. Once I’m out of the driveway, I usually take off

Frank, how I ride off depends on the ambient temperature, and the settings and habits of the particular machine I am on as each is different. I do ride off with the choke still on in many cases,

A few days ago Steve Ross, when inquiring about the choke lever said " *It looked to me like the lever is supposed to be kept open by friction so one can ride away while the engine is still cold".*

As Todd mentioned there is a cool trick to align the pads parallel to the rotor. Take a black sharpie and make a series of lines like spokes on the surface of the rotor. Pull the cap off at the bottom

Yes Hans Muth designed the lovely R90S, but Bob Lutz saw to it that the R90S made it to market. SO thanks Bob Lutz and Hans-Albrecth Muth!! We are very grateful! See

With four brake pads, there will almost always be some slight drag, but being very careful to adjust the eccentric precisely on both sides will help quite a bit. Of course he will want to clean and

Thanks to everyone for their feedback, I have passed it onto the new owner of the R90S. Mac Kirkpatrick Glenmoore, PA "After all, what is adventure, but inconvenience, properly regarded?" C. Donahue

I have to agree With Mike Mine didn't spin 3 turns ether remember you have 2 sets of brake pads on each side and they are in constant contact with the rotors.

My hunch is it’s just fine. Mine won’t spin 3 full revolutions even when cold and I’m not the least bit worried about it. I suspect he’s looking for the unobtainable. They aren’t like

A friend just purchased a '76 DO R90S which is in fine shape. But the front brake drags too much for his liking. He has adjusted the brake, looked in the manual for advice, followed all the "check"

also we had a guy at Death Valley with same symptoms and the kill switch itself was bad, broken wire. keith in oakland, ca

This indicates you have battery power to the clock but no battery power coming out of the ignition switch. Check you haven't bumped the kill switch by accident (you wouldn't be the first). If you have
