Thanks so much! Yes, the bike is really fun to ride! 😎

🤣🤣 well, good thing I ain’t going anywhere near Germany! But jokes aside… It would probably pass a “custom” inspection.

Thanks a lot! Bike had 43000km when I bought it. 🏍️

Hi! It’s an SW-Stahl 03926L Digital torque adapter. Works quite nicely. It’s 6-30Nm and there’s also the higher torque option: 03927L which is 27-135Nm.

@@volimoto Thanks! Have you tested accuracy of it? Right now I'm using standard cheap "clicky" torque wrenches calibrated with a fishing scale. It's a bit scary sometimes.

@Jaszczur-sp2tx I haven’t actually tested the accuracy, but I’ll try to remember to do so and report back to you. I’m away from home for the next week, though. Btw! I’m planning on buying a small 1/4” clicky torque wrench, 2-26nm for some of these jobs because although the digital adapter is great, there are situations when it simply cannot fit due to it being so tall.

Sure thing! Are you only changing the tensioners themselves? Or chain and guide rails too? The tensioners you can do without much disassembly, the chains and guide rails is a bigger project. Glad you enjoyed the video!

@@volimoto im only changing the tensioners

@Lanc321 is it also a superduke? Because it can be done without taking anything apart! The only reason you could is to actually be able to measure the chain elongation/guide wear. I think on the adventure or smt you need to remove some fairings and maybe the oil tank. The removal of the oil tank helps on the superduke too, but I could do it without, it’s just a bit more annoying. I actually have some home made manual tensioner in right now because I messed up the tensioners and had to do something quick so I could join my friends for a trip… so it’s gonna be nice to get everything replaced and also back to hydraulic tensioner!

@@volimoto yes its a superduke like yours. im gonna do it this weekend. how did you mess up the tensioners? they are very expensive where I live (95$ each)

@Lanc321 I was experimenting with a small spacer because I was trying to determine if it’s camchain noise I’m having and ended up compressing the tensioners too much and bent the ring that holds the two pieces together. But they were also a bit work out anyway.. €105 here… I ended up ordering them from the US from KTM world for 45$ through a package forwarding company and with the guides together it’ll be half the cost as it would have been here even when I pay the taxes. Shipping was surprisingly cheap for a small box!

That’s really awesome! Hope you never had issues with the water pump! It’s super awesome! The only thing I wish it could do better is pillion comfort so my girlfriend would be more comfy for some longer rides. But I mean, this bike is not about that, so it’s okay.

@@volimoto The only issue I had was the rectifier for providing stable current from the generator. Had to replace that on the 2008. Had a few SMTs too and they had no issues at all. Very happy with KTM.

@b0bl00i That’s awesome! I really have gotten to like this engine through working on it. I’m considering getting either a 990 adventure or a 1090 adventure to add to the stable.🏍️

@@b0bl00i What was the realistic fuel consumption? I have a 2008 690 SMR and I'm thinking about getting an SMT

@@Jaszczur-sp2tx SMT is a great motorcycle. Good engine, fun, wheelies well and is comfortable. It's the LC8 engine with 18L (or 19L?) tank, can't remember exactly. I think you can easily get 200 Km per tank if you're not pushing to hard.

Thanks a lot! It was really insane! No wonder the engine couldn’t turn over with the cylinder filled with oil… glad you enjoyed it!

Thanks so much! Really appreciate the kind comment! Glad you liked the video!

Hi! It’s grease I got with the rebuild kit, but I’m fairly sure it’s “red rubber grease” (It’s a brand also) and is meant to prevent drying out for natural and syntetic rubbers. Some don’t recommend actually greasing the sealing rings on the piston, lt of people instead use brake fluid there, but using a very small amount of this rubber grease makes more sense to me. Hope this helps!

Hi! They probably included the wrong material of hose. Try looking for EPDM hose. Depending on where you’re located maybe you can find it in your local auto store, or just order some online. It’s fairly cheap.

@@volimoto thanks! That’s the kind with the metal threads lining the inside right? Looks like black rubber hose, fuel line hose?

I think it’s just “rope” and not metal inside, but could be also that there are versions with metal mesh. Don’t use normal fuel hose. Generally what’s fuel and oil resistant is not brake fluid resistant and you might end up with the “sweating” action on them. Look for specific brake fluid resistant hose, which EPDM is. You can just google “epdm brake hose” and I’m sure there’ll be some available near you. I hope this helps!

It’s an awesome bike! I can’t wait to have some more time to get back to working on it! I’m planning to instead of uploading tiny sections at a time just finish the bike quick and upload a full video of the restoration/assembly. Good luck with yours and let me know if you need help with anything specific!

Es wäre sehr nett wenn Sie mir sagen können um die von Powerbrick sind oder von Bosch ??

"Hi! Das ist wirklich interessant! Ich habe die EV14s von Thom bei KPartsHolland bekommen, aber soweit ich weiß, haben sie früher dieselben Injektoren verkauft. Ich habe gehört, dass sie versucht haben, einen besseren Ersatz zu finden, also hast du vielleicht schon das Gute bekommen? Wann hast du sie gekauft?"

@@volimoto ich hab die gestern gekauft und hab ich mit Thom gesprochen, offenbar die sind Neu und auf seine Webseite hab ich Bildern vol die Injektoren gesehen . Die Sind Neu und genau wie Originale Injektoren sind aber mit 4 Loch . Thom hat gesagt ich schicke die zu Power Brick auch . Ich dachte dass die Fake sind aber die sind wirklich Neubrand und Geil 👍🏻 Danke für deine Antwort .

That’s true for the k1100s but K75 and early K100s don’t have O2 sensors or any feedback to correct the mixture.

@volimoto Dont know bout that. This was just the answer of a specialized injector shop.

Really happy to hear it’s working well for you! I think it’d be the same for the K1100 as well, as both yours and that already have the more modern Motronic injection, and not the L-jetronic as the K75s and K100s. The R1100 is a nice bike👍🏻

What is flex fuel kit? I'm owner R1100RT 97', want replace stock injectors to smooth rough idle.

@zettaker2181 That is the same exact bike that I have. Mine is blue. 😀 The flex fuel allows you to put E85 (85% ethanol alcohol, 15% gasoline) into your tank. The injectors are kept open slightly longer to allow more fuel into the engine. I highly recommend the EV14 injectors, new Bosch spark plugs and throttle body sync to make your bike run better than new. I don't remember the part number of the spark plug but I can find it for you when I get home.

First of all, I’m happy to hear you resurreceted the hybernated K75S! I hope it’ll bring you a lot of joy riding it! - It’s very interesting that even after doing all the cleaning it ran so rich! Have you tried cleaning the MAF sensor? (i know it’s not really a true MAF in these bikes, but for the ease if it let’s call it that). Or maybe the little door inside is moving a bit stiff? I’m glad you managed to get it run properly! I wanted to put mine on a gas analyzed but couldn’t find anyone near who had one.. there was a workshop my dad used to work for that had in the past but when I asked they said they sold it some time ago.. Let me know if the fuel pressure regulatir does the magic! And thanks for your comment!

When you say "air bypass screw" are you referring to the screw to adjust the co-value on the airbox right above the motor?

@@dduncker5457 Yep, adjusted with an Allen key. And I made certain the air flow flap was free in its movement ( very gently ).

Thanks for your comment. I think you highly misunderstood the purpose of the video.

In 1991 there was no 4 hole injectors...

Thanks! Yes… didn’t really have a dedicated metal workshop area so did what I could. But the lift is for sure making my life a hell of a lot better at being able to work on bikes in a comfy position. :)

Thanks very much for your kind comment! The base of it was 4 or 5mm I think, but the only reason is that’s what I already had laying around. The legs and top part is 3mm. I think the lift benefits from the extra thickness because the base is a lot more heavy, but I’m sure it’d work just as well with 3mm.

@@volimoto thank you very much.

Según creo las características del inyector Bosch 0 280 150 210 son 135,1 cc/min o bien 97.19 gr/min a una presión de trabajo de 2,5 bar y utilizando como liquido n-heptano , pero hemos de tener en cuenta que podemos hacer que trabaje nuestra LE Jetronic o nuestra motronic de forma mucho mas forzada ua-cam.com/video/KtFZ2C8fqCE/v-deo.html

Por favor por que indicas como referencia los inyectores 0 280 158 200 Si no creo mal estos inyectores proporciona 170 cc/min y/o 116 gr/min a una presion de 3 Bares, si el regulador de nuestras motos trabaja a 2,5 bares estamos haciendo trabajar los inyectores con otros baremos no testeados.

Hello! To my memory I found the specs for the K bike injectors at one of the well known websites for K parts. Funnily enough, I can't find the same spec sheet right now, and 3 different places list 3 different specs... But yes, specs are given for 1 minute of operation at 100% duty cycle, which you shouldn't do in testing because you can burn the coil inside. This store advertises the replacement for the original K bike injectors with the specifications I used for my testing ( 116g/min and 166cc/min, except for impedance being different) but this is not the page I've seen before: bavarianwerke.com/product/brand-new-genuine-bosch-fuel-injectors-for-bmw-k75-motorcycle-replacement-for-bosch-0280150210-bmw-part-number-13641460450/ The BOSCH injector BOSCH 0 280 155 969 is indeed EV-6. Those are the alternative injectors I purchased to install into the bike. I think they're for a 3 series BMW, but can't remember right now. They also have 116g/min or 166cc/min as the original K injectors were specced based on what I found info at the time. I don't believe I mentioned part number for the EV14s in this video. The injectors are from KPartsHolland and I had used the part number on the side of the injectors to identify specs. These injectors are originally from a Renault/Dacia. And importantly, I used my testing setup at 3 bars for all injectors, because the specs I found were given at 3 bars, and I wanted to maintain consistency between it all.

Yes, I was just using a small relay with 12V power controlled by an arduino to open/close the injector. It’d be very interesting doing some experiments with the jetronic system for sure. Merry Christmas!

( BMW K100 LT, without airbox and AFM in vertical mount with big cornet !)

I dont know why my message desapears, .. ok So I said that I made a piggy back with an arduino every who intercept injector command and chaage the timing (I need to remove 900uS to get a nice AFR, tested with wide band lambda sensor and confirmed by spark color !)

It’s really interesting to hear even 4V bikes have the same issue! I had also thought about messing around with an adjustable fuel regulator, and I think it could work! I’d be very interested to hear the results if you do so! - my only skepticism regarding the 4 hole vs 1 hole injector atomization that the new injector I put in are also 4 hole, yet they don’t cause the rich running. I’m still theorizing the the different impedance value is the culprit, but then again, my testing showed that in fact the EV14s sprayed less than the others… So please let me know if you test the adjustable fuel pressure regulator. Maybe with less fuel you’ll manage to get a smooth running engine and even reach better fuel consupmtion? I don’t see any reason why it couldn’t work by the way! And if you can’t get one that has vacuum line to it, remember to put a blind plug into the vacuum hose that comes off of the current regulator! Cheers!

⁠​⁠​⁠@@volimotohappy to get your view on this idea so fast! Yeah it’s weird the other 4 hole injectors work fine!? I’ll buy the adjustable FPR but it will be closer to spring for testing. Have allot of building to go on my K. Good thing you mentioned the vaccume hose will remember. And i’ll write about my experiments when i get so far!! I also have original injectors if all ells fails will just rebuild them.

@tf0087 sounds great! Looking forward to hear about your results! Happy building! And Happy Holidays!

Hello, I try EV14 on my modified air admission K100 and I confirm, it is running rich, very rich ! I use a Lambda sensor to test how much I am rich (at all rpm). I got an AFR of 10, even less than 10 !!! I try every thing to return to a better AFR but I couldn't ! ( change AFM settinf, spring, cursor position ...)

It’s really interesting that so many people had bad experience with these, yet they’re advertised so much and as they’re the greatest you can get for the K… thanks very much for sharing your experience!

That’s very interesting you have the same problems! I have also looked for the probem all those places, and couldn’t explain why it’s not running well. Hope you can fix it and looking forward to hear the results! Thanks for your comment!

Will you maybe lower the original forks? If I had kept them, I would have done so as it’s quite commonly accepted that a bit more weight in the front gives the bike more agile handling.

@@volimoto Yes, lowering the original fork definitely is the way to go...and this is relatively easy to achieve. Still I think it would be great to have a modern upside-down fork combined with the classical look of the BMW.....but beneath the huge efforts that you showed I see a high risk to never get it street-legal here in Germany.

@Straightleg55 Getting it street legal in Germany could definitely be a problem. I think to do that, the way to go is getting custom made TUV approved triple tree for the fork legs, so the frame doesn’t need to be modified. Good luck on your build!

Oh, and one tip for keeping the original forks but upgrading the brakes… If you have a mono-shock airhead you can put on the brake calipers from a 4V R of K bike of the era, and use a brake disc from an R80R or R100R to match the offset of the calipers. It’s a straight bolt on. I have 4V calipers on my K75 with R100R discs and it’s a massive improvement over the stock. You can probably use the 4V calipers on the twin-shock bikes as well, the bolt distance is the same, but need to figure out how to get the correct offset for the disc.

Thanks! And ouch! It’s never fun with fuel all over…😅

@@volimoto can give the link to injectors

@harpindersingh3401 I’ve get them locally from an autostore but you can find them on eBay or Autodoc. If you’re in Europe here’s an eBay link: www.ebay.com/itm/385448715833?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=R5Wcwwv3Smy&sssrc=4429486&ssuid=oPDL6EmxRpS&var=&widget_ver=artemis&media=COPY UK autodoc: m.autodoc.co.uk/bosch/1150376 Hope this helps!

Hi! Since the jack is wider in the back I made the 2 different widths so it can guide it to go straight. It’s not necessarily needed, but I think it helps. To upper assembly for me is made of 2 only because I already had some metal frame and wanted to use it to save on some materials. Thanks a lot!👌🏻
