Amazing, thanks. Could you please share the putter diameter of the tool and the thickness of the teeth? I’m trying to build my own tools :)

What tool do you use for the pinion ring nut? Looks like a bolt? where did you get it?

My odometer mileage just went from 15k to 56k on a 5 minute ride. I'm about to use the video to remove and repair what ever went wrong. Will I be able to rotate those the miles back to the correct numbers with out causing more damage?

Awesome, thank you!

many thanks for your very informative video. Absolutely helpful and priceless. I am going ahead and will order from Matt(R90x designs) the parts I need to convert my brakes (BMW R90/6 early 1974)to exactly what you just showed us. My concern and question would be, to operate a brake lever with integrated master cylinder, how would I be able to get away with the setup I am having now which is an integrated brake lever and throttle twist grip? Any advise would be highly appreciated. Many thanks Felix

Hi from Germany, its called Verschlimmbesserung, excellent Videos!

All talk no action

The seal replacement??! Help! Is my 1975 R90/6 different? I did not pull out two rings. There is just a single seal. I paid a crazy $39+ for it from Max BMW.

Did you check the wires going to diode board? I was told that maybe wires are connected to wrong screws there . Not the insulated terminal but the bare ones. I was having same problems with my mechanic trying to install dyna 111 ignition and he couldn’t get two new ones to work without similar issues your having. Only having put back to points did the bike ride normal again.

I suspected that the Dyna III ignition on my '75 R90/6 (unknown date of install) was failing (misfires, stalls) because of heat (I live in the US south...) so I just replaced it with an EnDuraLast EDL 4 IGNS. Hoping I won't encounter the problems you are having! You've probably sorted this out on your bike by now, but I wonder if the location of the ignition unit might have been a problem. I put the new unit by the seat (as far from the engine as possible). So far so good, but we are only now moving into warmer weather, so time will tell. Really enjoying your videos - I'm about to replace the rings and push rod seals on the bike, and your thorough demonstration on R75 is helpful!

Good that you don't use music but consider getting a mate to do camera work. We cannot see what you are doing, sorry but this greatly reduced the usefulness of the video just leaving a camera way too far away from the action and also, try telling us what you are actually doing as you do it. (Post production narration perhaps?). I am airhead owner for 30 years now and will watch this anyway, and thanks for your work, great that you shot it in any case... Hope you don't mind some constructive criticism to help you get more views etc. in the future!

Excellent instructional video. Thankyou.

Are there any tricks on removing the shock mount out of the Final drive? I need to replace mine. Your advice will be very much appreciated! Thanks

I have a ‘72 75/5 and the front drum is very poor. Would love to find a cheap replacement to get a disc or two up front!

How did you clean the engine castings?

Really interested in this series as I’m rebuilding an R50/5 engine. I just couldn’t bring myself to do that inner oil filter bolt up to 40nm. Seems way too tight. I did it by feel but would estimate about half that figure.

👍 up on start up

is that your POP helping out there.......purhaps you should introduce him to us!!! great content ......if you ever replace the Crank bearings especially the rear one please video it completely even if it take one or two whole video's please.......and thank you for sharing

thank you

Great video, thanks for the clear breakdown on inspection and testing procedures

Thank you for the tips. Rebulding the breaks is my week end job today ! But my question is about your topcase with the back seat. Have you a reference for it ? Thank's

Wow! That bike looks exactly like my old R80/7.Even the lester mags. Same color, faring. Mine had a Alfabet 2 into one pipe. Really miss that bike.

That's great to see. I haven't stripped an R90 engine for 36 years 😬 Coincidentally, it had a gudgeon pin circlip that had jumped and marked the bore, although it was only in for weeping bases.

Wow you were really lucky to find that circlip in time. Any damage to the cylinder? Hope not. Thanks for sharing, Happy new year😊

This channel is a joy to watch and learn from. Love it!

Great video. Where are you located?

Good work 🇸🇪🇸🇪🇸🇪

Great video. Thank you. What is the viscosity of the oil and is it regular fork oil?

Lightened flywheel? Looks like a 100S that I had machined out.

Another really interesting video. Good tip about blocking the crank to prevent it moving forward but in reality can that actually happen with the barrels and pistons fitted ?

I will be re watching this entire series when I get around to doing my 75/6. I have to call ahead and get a reservation if I plan on stopping 😂. Also I’m not far from you, if you need a bandsaw you’re welcome to borrow mine.

Hi Damir I sent you a message on instagram

Thanks for the video Damir. I have one question. I have seen and done this before but it was always heat it up and beat on it until it comes free. You were using a thermometer and I’m just wondering what temperatures you’re looking for.

Hi sir. Where can i buy part koni 7610

Patina really is good because you can relax and ride the bike with no worries at all, I'd only change the seat back to standard

first

Hello, thank you for the video. At 33:31 in the video you are in the process of pressing off the flywheel from the crankshaft. You regularly look at the front of the motor during this process. What are you looking at? Is it the front of the crankshaft that you are looking at? I'm looking to do this job in order to check the condition of the oil pump.

Mine was having the same symptoms with hiccups and backfiring. I’m still in the process of investigating, but when I removed the tank I noted that the black wire that goes into the ignition module had come loose. I briefly rode the bike and seemed to be fine, but I need to ride it longer to confirm.

I’m considering doing this upgrade in addition to having a brass sleeve installed in the master cylinder. Do you think the shrinking the master cylinder diameter from 14mm to 12.7mm will negatively effect performance when used with a brembo caliper?

The "STADIVARIUS" of motorcycles, just gets better with age!👍

Interesting.

Y not show the pin removal that holds the needle bearing on the pinion pocket?

Why didn’t u show removing pinion gear bearing pin ?..??

Can not believe they didn’t use a screw instead of a pin w/ no way to grab a hold of !

Time to build a Drag car, okay maybe even a drag bike...

Well diagnosed. Strange that those flywheel marks are missing especially if the ‘f’ mark is still there 🤔

Nice job. Another reason to use points :)

for the algorithm tank you

What have you got yourself into? One of the most beautiful BMWs ever crafted! I remember the literature in the 70s when that came out the picture of an orange bike hurdling around a corner at a great lean!

I have exactly the same but the 800 version from 1980….. okay, I’ve got the original alloys
