Thanks for the video. Be really careful with any corrosion on the small spade connector on the starter motor. It is used to control the load sensing relay. When it gets a bad connection the bike loses most of its electrics, the ABS turns off and all the lights go! I had it happen on a winter's night while traveling 70km/h on a country road. Pure luck that I stopped before driving blindly into a ditch. Such a flimsy design for a critical component. BMW should have used a bolt connection and protected it better form the elements. Anyway, hope this helps you avoid having the same experience that I had. Cheers.

You're lucky. I have the 2014 R1200RT and I spent most of the day trying to get the starter motor out. The manual says "remove screws" but don't tell you that you will be pulling your hair out getting at them. I ended up welding a Torx bit to a piece of round bar. While this could only just get to the bolts between the frame, I then couldn't turn one of them because it will hit the frame no matter what. I ended up ordering a micro ratchet and I hope that will let me get it out.

Did you had a chance to do it, yet? If not, worth watching Chris Haris, he has a video here on YT on replacing a starter on a 2004 bmw r1150rt; using extensions helps (talking about 2-3 feet, in his case, I believe). I wonder how different might be from your model. There is a certain way to get them out on the rt, that he shows, tilting it a certain way. Also it helps getting a long 6 mm ball end allen (atleast on the 2004 that is what they use), that allows a fery helpful tilt into the rear bolt, between the starter and body of the bike. I think the allen ball end idea actually came from another video, from "the bmw guy", also has a good video on the topic. Got my ball end allen today from Harbor Tools, and ordered a starter last evening, ready to replace mine as well! After watching Chris Harris, I ended up ordering the Enduralast rather than Valeo, it seemed he favored the aftermarket better than the original for some reason.

@@t.s.3669 Completely different bike with starter in a different place. I did get it done with the small ratchet I ordered and it made no difference. I think I have another issue, maybe a bad ground somewhere. Cleaned up the relay connectors too. Maybe my battery is just old, but running battery diagnostics it says it's fine. I read 12.8v going down to 11.6v on a load test, but a cranking test makes it go down to 8.6v-9.4v. It doesn't make sense. I cleaned up all the wiring. It's not as often now but every so often it sounds like it is struggling. I did notice the starter feels stiff to turn by hand though when reassembled. Not sure if that's normal because of the strong magnets? I smoothed the commutator in a drill press and the bushes have plenty of life.

@@ArcanePath360 I was about to ask if you checked the negative battery to the frame connection, but then I realized you mentioned checking all the wiring, already. How old is your battery, I wonder. Mine lasted 4 years, even though always on battery tender, but indeed, different generations, and when it comes to electronics, they could be sensitive. Did you had a chance to check/scan for any error codes? Some owners report issues with the starter magnets, at various years/models.

@@t.s.3669 I bought the bike in 2021 and it looks like the original battery as it's markings show BMW and it looked a bit old, so cannot say. However with a surface charge the bike does seem to start easier. The terminals did need a bit of sanding /wire brushing to shine back up but weren't too bad. No white corrosion just a little green and black. The markings on the battery show it has 200CCA, but when you go to replace it, you have the option of 240 (or maybe 220 I can't remember) or 270 for a better one for this bike. It might be that it's not very healthy but I am getting other weird symptoms... Sometimes my fuel pump makes a creaking/buzzing noise after I shut off the bike, maybe like a fan on hot days and then there's a loud mechanical click after about 30 seconds where it stops. I know that my servo motor in my exhaust also doesn't do a self check, it doesn't rotate at all but doesn't seem to affect anything. And my fuel pump always makes a little noise when it primes as I first turn the key, but never stops. I'm sure it used to shut off after a few seconds but now it doesn't. It feels like something is draining the power. A multimeter shows my voltage dropping by about 0.01v per second until I crank. Not sure if that's normal. Unfortunately I don't have the expensive code fault finding tech. I think they are massively over priced for what they are.

@@ArcanePath360 Indeed, de priming fuel pump noise should stop after a second oe two. Too many electronics in those bikes nowadays, some glitches just caused by electric supply variations. You can find a cheaper 911 scan if you look on sites like ADV rider, they might only work on 1-2 bikes (vs the new ones I believe you can register up to 4 or 6 bikes), for about $200. If you can get one, highly recommend it, it would pay itself even if you needed once to erase some gremlin code that might prevent the electronics from starting, down the road.

Yeah this is common abs lack of power issue. There is a work around. Abs module is wired into something that Starves it till you get moving. Can’t remember. Gl

Is that what the whirring noise is when you turn the key before firing it up? I'm having startup issues and when I crank it sometimes draws too much power and the bike does a factory reset on the display. Only sometimes though. But the whirring noise sometimes doesn't go away before I crank it. Is it the ABS pump or servo inside the exhaust getting stuck maybe?

I'm about to do the same inspection on my starter. Did you check the bushing on the bendix gear? I believe that can cause some problems if it is worn out. Also, you may want to see if you left side cam tensioner has been upgraded to the newer design. That will make a huge difference in the sound of your engine when it first starts. Good video....and it's nice that you're not just changing a part, but trying to actually fix it! I've been riding BMW motorcycles for over forty years.

Hi thanks for message. Yes I checked start and all looked OK, and I replaced tensioner 2 year back. I think because pistons so big its hard for starter to make 1st turn.

@@bikescarsdiyskydiveeveryth1507 Okay, here is what I think is wrong. Starter position. The aftermarket starter does not have a locator dowel-pin. Check closely and you will see a hole in starter where a pin should be. It is near and to the outside of the bottom bolt that holds the starter to the engine. There is a hole for the locator pin on the engine block that lines up with it. I made a pin and just as I tightened the starter bolts I turned the starter slightly clockwise. This was a good improvement , but I decided to loosen the bolts, turn the starter counter-clockwise, and then re-tighten. This seems to have fixed the problem. So....aftermarket starter needed the locator dowel-pin and maybe just a little adjustment in the starter positioning. Note: Having the starter in the wrong position can damage your flywheel.
