Throttle body rebuild on BMW R1100 and R1150 with Cata Dan kit

[@hmroa3056]

At 13:18, it's important to state that the shaft needs to be properly oriented, or it will be off by 180-degrees, when reassembling the butterfly. The small screws and chamfered holes must be on the same side of the shaft as with the butterfly.

[@onomatopoeidia]

Did mine following your guide thanks. I used the old shaft to drive out the old bush with the tap in place. I also found it easier to put the circlip on first then insert the shaft from the other side. My body was worn due to the back and forth slop from the old shaft so I used kneadable epoxy metal putty to build up the damaged area and then filed it down. Gave me a new area to install the o-ring. Thanks for sharing.

[@markmath2883]

Thank you for including the method for removing the cap on the right side.

[@jimmylang8039]

Thanks for the great video. I did both sides on my 04 Rockster👍 Your video was a confidence booster on getting it done and not getting lost in the steps needed. I had to use a 3/8 tap on my setup to pull the bushings.

I installed this Dan Cãtan Throttle Body Rebuild kit myself on my 2000 BMW yesterday The task was quite simple, and only the removal of these original slide bearings, which had been in place for over 20 years, was a bit of a challenge. It was difficult until I realized that an 8mm bolt sawed into a 20mm slot on one end would work very well as a bearing removal tool ;-) Also, I noticed when disassembling my own BMW that the pulley ends didn't have the shims Dan Cãta described that I had to find elsewhere, so the mounting shoulders for that axle would have been perfect for another installation in the future. Otherwise, this operation was easy to do, and the end result now completely satisfies me. Different from the way of making this video, I myself used the old bearings as a "spacer" according to Dan Cãta's advice when installing the new bearings, as well as a long 8mm bolt that extended completely through both holes, so the chances of failure were minimized when the new bearings were hammered into place. The original problem was the TPS which I could not adjust to the set margins under all conditions and now works 100% fine.

Can you please advise from where did you get the repair kit?

[@glenhowatt]

Excellent detailed video. Great lighting and no wasted time! Thanks so much

[@thomasdabb8393]

Thank you! Well done. I just picked up a 2000 R1100S. Hope I don’t have to under take but am confident now I could handle it - thanks again

[@RAFTERMANCOLO]

Nicely done...!! Better than some professional videos I'v seen..! Keep up the great work and please keep the videos coming..!

[@VintageJunker]

This is a great video. Well done, very thorough step by step procedures. Great for the d.i.y. BMW owners who want to take care of their machine and save Bank! Plus doing your own repair work gives you a whole new respect for the Machine. Much Thanks!

WARNING: The left Throttle Housing Assy for the R 1100 GS / R 850 R / R 1100 R currently cost $715.05 and $488.92 for the right side. I haven't done this produce yet, but when I do I plan on being very very careful.

[@AnalogDude_]

792,46€ for left and 406,39€ for right. You might better off, the buy them second hand and try on them.

[@Eric-Marsh]

Would a spot of loctite be good on the butterfly screws?

[@hmroa3056]

Self correction: At 13;18, the position of the shaft is not really important, unless you prefer the nuts of each butterfly retaining mini screw to face downthroat or upthroat of the throttle body. The butterfly is inserted in the gap of the brass shaft, not on one side or the other.

[@jonandrews4493]

I put an arrow on my brass butterfly when I removed it, as it had 20 years of sitting in the same position/direction, I was concerned that it could be reversed and or rotated when reassembling and thus not quite sitting the same in the body, not sure if it makes any difference though, but to me it seems logical to insert it in the same direction as when taken apart.😂

[@patricklynch396]

Great video. What should I do if my disk wont close flush anymore?

[@GuysGarage120]

You will need a new disk. I have a jig to make new disks. They are actually oval and not round as they are positioned at an 86° angle in the throttle body. I also make my own shafts when I rebuild these throttle bodies.

[@patricklynch396]

@@GuysGarage120 Thanks for the reply. I actually just had mine in backwards!

[@leondantuma7123]

How can one see the proper side and direction to mount them?

[@ericsokoloff89]

@@leondantuma7123I lightly marked my disks before disassembling & later scribed on the disk were it slips into the shaft so as to not induce anything that may get cause abnormal airflow across the disk.

[@gabidagon]

I’d like to only change the spring, i can leave the position sensor in place in order to avoid adjusting it?

[@vidasgruodis696]

Thank you man. Great Video!

[@davidgreen424]

I wanted to see how you got that cir clip imstalled , because there's no way I can compress the rubber washer underneath enough to get the clip in the slot .

[@Seraptin]

On the R1150 you dont need to do the TPS adjustment. Just turn on the ignition and twist the handle to full throttle a few times. The ECU will calibrate to the min. and max. values of the potentiometer.

[@josemoricartategui6556]

I do not have the GS911. I read that the TPS voltage value with the engine idling should be 370mA

[@JohnDoe-bf1fw]

@@josemoricartategui6556 I believe you mean 370mV (.37 Volt) not 370mA.

[@mmm4638]

Is it the same on R1100GS?

[@Kjoellereu]

Hi Seraptin. I have the R1150RT and i will rebuild with this kit 👍🏼 When i’m done i simply just have to turn on ignition and then open/ close throttle a few times. Then the TPS is calibrated?

[@GuysGarage120]

Adjusting the TPS is critical on these bikes to get the idling correct. Contrary to popular belief, twisting the throttle does absolutely nothing. It is unfortunately one of those myths that just won't die. The correct way to do it, especially after replacing the shaft and butterfly disk, is to back off the butterfly stop screw completely and allow the butterfly to close completely. Set the TPS to give you a voltage of 0.25V, and lock it in place. Now readjust the butterfly stop screw until the voltage reaches 0.36V. Lock it in place. Turn the BBS in all the way, and then out by 1½ turns. On the RHS, turn the BBS in all the way and back out 1½ turns. Now adjust the butterfly stop screw to get the balance correct on the vacuum gauge at idle. Bring revs up to ±2500RPM, and adjust the cable stop on the RHS to balance again.

[@tassoskard8157]

Hello, is there a link or something for the repair kits? I am afraid that I cannot find them anywhere

[@markmath2883]

I just broke the left throttle arm on my 2009 R1200RT by twisting the throttle to hard. The plastic case is broken. Any videos or advice on how to replace?

[@HK-nl3ih]

What are the symptoms that this rebuilding will fix?

[@owenmostert2330]

Hi. I have a 2020 BMW R1250R where the butterfly valves are pinging in the Throttle body assembly (from brand new to current +/_ 6000Km's). BMW say that its normal, but I say it isn't, as the noise is very distracting. Its very noticeable under load from around 2000rpm upwards in all gears. I have a video clip that I could share. Do you have any recommendations?

[@onomatopoeidia]

Thanks for showing. About to do mine as they are as noisy as a can of nuts and bolts :)

[@markebbage9996]

Great video

[@2404Pepe]

One of the best videos on KZbin. Thanks!! Q: I have an RT1200 2012, the one with the new engine. I was dum enough to unscrew the air screw on the throttle body, yes, that one that you're NOT supposed to move. Anyhow, do you know any way around buying both throttle bodies new??? cause, that's what BMW dealer proposes, due that they haven't been able to sync it right. Any idea will be welcome, Thanks again

[@GuysGarage120]

The 1200 throttle bodies are relatively easy to set up. Use a piece of paper about 5mm wide and 150mm long. Remove the throttle body from the bike and turn it so that it is pointing straight up. Open the butterfly and insert the one end of the piece of paper into the gap, then close the butterfly, trapping the piece of paper in place. Add a small weight (A coin works best) to the other end of the piece of paper. Now carefully turn the stop screw clockwise until the paper falls out. Repeat on the other throttle body, and refit to the bike. The idle actuators will do the final balancing automatically while the engine is running.

[@adrianclay2949]

good kit, struggling with the balancing though

[@littlecente1133]

My R1100RT is twenty years old - should the inside of the throttle bodies look so clean as this? Mine are black and filthy!

[@edgarovsepian1067]

Clean them out and change the air filter.

[@JohnDoe-bf1fw]

I have a 20 year old R1100R. Today I removed the the left throttle body to replace the cam chain tensioner. Yes, my throttle body was also black and filthy. It seemed there saw a very little play in the throttle body. I'm not sure if I should get a Cata Dan rebuild kit or not. It doesn't seem that bad.

[@markk4919]

how is K1200Gt clutch? still going strong?

[@MauroEUA]

Hey Good afternoon. I'm having a problem with the rpm of my bmw 2002 r1150r. When I stop in the signal or I take my hand off the accelerator, the motorcycle dies. I changed spark plugs, new gas, new air filter the mechanic said i have a fuel injector problem... i bought a two new but this has the same problem. what could it be? thank you so much

[@mmm4638]

Maybe TB is bad and out of Sync did you endup fixing it? If yes what was it?

[@javierchavez2821]

I’m having the exact same issue, but I have avoided spending money on it since I have yet to pinpoint exactly what the issue is. How did you solve this issue?

[@zordonthevoyagesof577]

thank you so much, dude.

[@danielbre942]

Where can I buy the body with the bushes ?

[@alanrichardson1672]

To secure the butterfly fasteners it would be better and more professional to use threadlock. If one of those nuts or screws finds its way into the cylinder it would do a huge amount of damage to the engine.

[@Tax2Me]

Why not using heat gun?

Good information but one point is I have no M9 tap, just M10 so I proceeded thinking it was possible. In my opinion you’ll damage the housing with the M10. Tomorrow, I’m buying an M9.
