    You make fantastic videos and give excellent instruction, thanks for this. I am new to BMW with a used '23 1250GS and have purchased the full tool kit from Pilz. My question is what mileage would you recommend doing this procedure? I plan to keep this bike for a long time and like to stay ahead on maintenance. Thanks!

    • @Boxflyer11
      @Boxflyer11  2 месяца назад +1

      It's not a "necessity" to do this Cam Timing...as a matter of fact, the only reference to using these tools in the BMW Service DVD is to use them when a Camshaft is REPLACED.
      That said, if you live anywhere close to New England in the USA, where I live, or could attend one of the BMWST.COM START or FART Rallies, I do this procedure on 2 bikes a day.
      To answer your question, the engine needs about 12k miles to allow everything in the valve train to break-in and normalize before doing this. If you do it before that, then you might need to do it again after it gets 12k miles on it...if you have well over that mileage, no problem, you will just enjoy a smoother engine that might run better.

    Is the pre-tensioning (12mm) of the cam chain the same for the 1200LC engine? Is that pre-tension also required if only valve clearance is checked?

    • @Boxflyer11
      @Boxflyer11  28 дней назад

      When using MY DIY Cam Chain Tensioner, yes 12mm of bolt extension is the same for the WetHead and the ShiftHead. This is NOT a direct application of tension on the Cam Chain...it's what's required only with MY DIY TOOL and is completely different than the number of turns with the OEM Tool. Totally "Apples and Oranges". There is no need to use any kind of cam chain device to do the Valve Clearance check. If you are just "somewhat close" to being at TDC, as evidenced by the piston near the spark plug hole, and the laser etched marks on the ends of the cams being "far apart, away from each other" (on the R1200 WetHead) then you will have the cams on the base circle so you can measure the clearance.

    Where did you find the specs and procedures? BMW has made their manuals online and dealer only access. My shop can't access them for 2021 and newer because I'm a private shop and not an official BMW dealer. Even though I am BMW factory certified.....

  • @CXhaust

    At 4 minutes in you use your tool to rotate the camchain sprocket. I notice you turn it in a CW direction (when viewed from the rear, face-on) so that the tight side of the chain during rotation would be on the bottom. Wouldn`t this put undue strain on both the camchain tensioner and guides? It could also introduce any slack in the chain to the top chain run causing camshaft timing retardation and failure of the camshaft setting tool to fit, or is this known by BMW to be the case and is what the camchain tensioner special tool is for - to tension the lower run of the chain thus eradicating the slack on the top run thus pull the camshaft timing back to spec? If so it`s a rather crude way of doing it..
    Ideally during camshaft timing and/or valve clearance adjustment it is the crankshaft that should be turned in the normal direction of rotation but there is no provision for that on these 1250 engines.

    • @Boxflyer11
      @Boxflyer11  4 месяца назад

      This is just the way the BMW Service DVD specifies the engine to be tuned over. There is very little resistance on the crankshaft once the spark plugs are removed.

    Hi, first of all let me start by saying that it is a pleasure to see such an organized way of working while at the same time explaining everything very clearly. I have a 2021 BMW R 1250 GSA with 9k km, with an annoying rattle between 2k to 3.5k RPM coming from the left head. Despite many attempts at BMW dealership, they say the sound is normal and no solution has been found. Today I drove another 1250 GSA from the dealership with 2k km and that one didn't have that annoying sound. In you experience, did you ever come across any 1250 engine with a ticking noise beyond normal and if so, could your provide some guidance/advise? I'm conscious that all boxer engines are noisy but not like a bag of nails inside the engine. Many thanks from Portugal

    Impressive; thank you. Three questions: 1) what symptom would you expect to hear/feel from a boxer engine that is not perfectly timed? 2) do you have any guess of the % of engines operating that are not correctly timed? 3) is checking timing a usual and customary shop service/check?

    • @Boxflyer11
      @Boxflyer11  2 года назад +3

      Hi Andrew, answers to your questions:
      1) I think that a slightly out of time set of cams generally runs a little rougher, both at idle and at intermediate RPMs as well. Sometimes it represents as hard starting, but that is more likely the timing reluctor being out of time, and is part of establishing correct alignment for all the valve train components. There may be a little less economy also from less than optimal flow thru the heads.
      2) My experience with doing about 100 Cam and Valve checks is that about 85% of the "First Look" timing checks need some adjustment of both the cams and timing reluctor.
      3) I don't know for sure, but I don't think shops would do a Cam Timing check unless some part of the valve train was disassembled for the replacement of a component. This procedure is not called for in any of the normal mileage or calendar service sheets.

      @joost1183 5 месяцев назад

      ​@@Boxflyer11 I can confirm that a bmw dealer does not do cam timing checks and alignments. Quote: "we can only replace the cams."
      You might also get excess vibration between 4200-4800 rpm on wetheads 1200 lc.
      Because of the special tools needed it's unfortunately something I cant do myself. These tools are hard to come by.

    Great videos, thank you very much. I'm going to be taking this job on later this week. I noticed a slight difference from the R1250 service manual. After the ignition timing is adjusted, they remove the alignment jig and the TDC locating pin, crank the engine with the barring tool until it is at TDC again, lock it with the pin, then re-install the alignment tool a second time to check the timing. Do you see any value in this?

    • @Boxflyer11
      @Boxflyer11  Год назад +1

      That would be fine, BUT, I would not keep the tension on the Cam Chain Tensioner. I'd slack it off before turning the engine over to relieve some of the excess pressure on the slack side of the cam chain...it's just too tight for turning the engine over. It's basically doing another complete setup to check timing after you just went thru the setup to align all the components. I DO turn the engine over after checking and replacing any of the valve shims with the Cam Chain Tensioner slacked off. This has proven to give me credible readings immediately after touching all the surfaces that can leave "crap" on these critical clearance surfaces...it's my practice after doing well over 100 of these checks.

    I think, there is a slight mistake in the video. According to BMW RepROM:
    Camshaft sprocket to camshaft tightening torques

    Exhaust, right, M10 x 1.25 x 25 - 10.9
    65 Nm

    other camshafts, M10 x 1.25 x 35 - 10.9
    60 Nm

    In the video it calls all 65 Nm

    • @Boxflyer11
      @Boxflyer11  2 года назад +2

      I think there is a huge mistake in the BMW RepROM.
      If you want to have a go at figuring out why a single 25mm bolt that’s the same bolt as 2 others gets a different torque than the single 35mm on the LH EXH, that’s the only different one of the 4…have at it.
      I believe that paragraph is wrong and the only way to error on the safe side is to torque ALL the bolts to 65Nm.
      I’m doing soooo many of these that it would be impossible to catch up with every bike that would be under torqued following the BMW way so I could add 8% to 2 shorter 25mm bolts and 1 bolt that’s 35mm long.
      Do what you like, but I doubt BMW will respond to this error when they won’t share the RepROM with anyone.

    Good morning, I have a 2023 BMW rt and the engine rattles and I’m thinking something is out of timing. I traded in a r1250 gs for a 2023 r1250 rs for my California bike for my daughters house. This engine runs perfect no clatter no noise when under load. Both engines run perfect at idle the clatter on the rt is only when under load and generally when letting clutch out although it does still clatter when under load. I’m going to bmw this morning because the turn signals don’t cancel and the engine noise. I’m certain they’re going to say it’s normal engine nois which it isn’t. Are the mechanics at bmw dealerships qualified or capable of doing this at the dealership like you did or do they avoid this at all costs. Also where do you work out of I’m in the Chicago area. Thank you Duane

    • @Boxflyer11
      @Boxflyer11  5 месяцев назад

      @duanecarlson5008, working with the dealership can be frustrating...at times, but while still in the warranty period is really their business. The relationship of the clutch noise and clatter under load sound to me to be different sources, but one thing you don't mention is the miles on the bike. I've been doing borescope documentation on the last 15 or so bikes I've worked on...almost every bike under 15k miles still show that both sets of valves have not seated completely. What this can result in is poor sealing of the combustion chamber making uneven power pulses. If it's the intake valves that are still breaking in, the intake charge can be affected so that even more uneven combustion occurs.
      Overall assessment, is that running the bike with lots of heavy throttle (but not high RPM) to finish the break-in of the engine is critical...nothing that the dealer, or other maintainer can do, it's the process of getting everything settled in with the engine to make it run smooth.
      The Service DVD only references using the Cam Timing Tools for replacement of a camshaft...NOT for the re-adjustment back to factory original setting that I do in this series...dealers are not inclined to do this for any complaints related to noise or perceived poor running.
      Another important maintenance step in this troubleshooting effort is to use some high PEA concentration fuel system cleaner. I don't recommend using more than 1oz per gallon of fuel, and try to only do 2 tank fulls per oil change to guard against oil contamination. (recent oil analysis does not show degraded oil quality, but enough is enough) I like Redline SI-1 or Chevron Techron.
      I'm in Rhode Island, and work in my garage. I'm not a business, just an enthusiast working for free on other folks bikes...I don't charge for any work I perform.
      Good luck with your bikes.

    Hi, love ur channel, I have got a r1250rs, with a damaged cylinder head, the chain has been knocked off and I’m replacing the head. Is there a way of timing the head without the cam setting tool? My local BMW garage will not sell me the tool.
    Thanks Jason

    • @Boxflyer11
      @Boxflyer11  Год назад

      @jasonlee8282 You can physically configure the cams to be coarsely aligned (in the right gear teeth) once the cam chain is installed. (If you have not changed the relationship of the cam drive gears to the camshafts themselves) This can be done by using the laser etched marks and 3 flat sides on the opposite cylinder cams. Set the "known cylinder" cams 180 degrees out of TDC by rotating the engine so you can see the 8mm slot in the access plug on the side of the engine. Then you can install the newly installed cams so that the intake cam has the 3 flat sides up and the 2 vertical sides are parallel to the machined surface of the head. The exhaust cam needs to have the laser etched mark on the end at the bottom and the flats also parallel to the cylinder head.
      At this point, you need to do a Valve Clearance procedure.
      The engine should run at this point, but the full procedure of using the 8mm TDC tool, the Cam Chain Tensioner, and the Cam Alignment Jigs would be highly recommended to set both sets of cams, and most importantly the LH Exh cam timing reluctor for the engine to run exactly as it came from the factory.
