R 1100/1150 GS/RT/RS/R/S throttle body repair kit

[Dan Cãta]

I can re-haul intakes for all 1100 an 1150 BMW boxer motorcycles.


After using the bike for a few years, the spindle and the intake bushings get worn, resulting in the spindle play, resulting in that annoing rattle and may leading to bike surging.


I can fix your intake if you send it over or I cand send you a complete rebuild kit and do the work yourself.


A kit contains:

• a new splindle(shaft);
• necessary bushings;
• set of complete o-rings;
• the small screws that hold the plate to the shaft.

Having the intake full repaired is just like having a new one, but at a fraction of a cost.


Just contact me specifying what bike model do you have and the manufacture year.







The price is 60$ + shipping.

Hey Dan, I need one of these kits on my bike bad. Im tired of having random numbskulls commenting "your valves are rattling". I've got a 95 r1100gs. Im in the process of troubleshooting a no start problem right now, but would like to make your kit the next purchase after I get that straightened out. If you don't mind, can you email me the price for having you install it, also any contact info and payment instructions. My email is cpuckett812@gmail.com. Thanks, have a good one

I will try to describe how to install the repair kit for the right side TB.
No special tools required, just what you have around in the garage is enough.

Once you take the TB off from the bike, you have to:

• take off the 2 small screws holding the plate to the shaft;
• take the aluminum cap off;
• go WOT and take off the throttle plate from the shaft by pushing it towards one side or another in the throttle body;
• take off the big screw holding the pulley to the shaft;
• take off the pulley from the shaft;
• put the throttle spring and plastic spacers somewhere;
• get the thin washer and put it somewhere secure;
• take off the o-ring towards the pulley;
• using your fingers, push the shaft out towards where the aluminum cap used to be;
• take out the outer o-ring;

You will now have the shaft and a washer and a c-clip on it. Take them off.

Disassembling is pretty easy, just follow the above steps in the order I have written them and it should be ok.

Now... How to reassembly everything.

First thing is to get the old bushings out. They might not be worn, but you will have to take them out and put the new ones from the kit instead.

This is what I have used to get them out. Some may say you need to heat the TB in order to expand and get them out easy, but I consider that they are too small and expand themselves because of that.



At the right side, there's a 13 screw. In the middle, there's a piece of copper wire, it has to be a 1 piece and not the multi-thread one.

The thing is, the screw is not as thick as the bushing, so you will have to put the wire in, and then screw in the smaller screw, so that it makes a thread inside the bushing and allow you to press it back form the other side. A screw tap is better if you have one around, but I didn't.





I have used 2 pcs of wood to support the TB and the longer screw inserted in the other side to hammer the small screw out, together with the old bushing.



Do the same thing in order to take the other side bushing out.

Now it's time to put the new bushings in.

Oil the outside of it for a more easy install.



On the longer screw, adjust the nut in order to get this:



What you see near the nut is one of the old bushings, used to press/hammer the new one in.

Put the new bushing on the hole and gently hammer it in a little so that it stays in place. Don't press it to far in because it will bend because of the hammering.



Now... put the long screw and the used bushing on top of the new one and press it in all the way.





Have a look from the inside of the TB to make sure that it's seated all the way in. It should look like this:



Do the same for the other side and you will then have this:





Now that you have installed the new bushings in, it's time to assembly the rest.

Install o-rings on the both sides, over the new bushings:



Now, take the spindle and put the c-clip on it and the thicker washer under it like so:










Now press the shaft from the aluminum cap side towards the engine side:





Now put the thinner washer over the o-ring like so:



Put one of the plastic washers over the shaft:



Put the spring back on:





Put the other plastic washer over the spring.

It's time to pot the pulley over the spindle, but first, and this is important.

The spindle has 2 holes in it, where the 2 small screws would fit in and hold the plate. When installing the pulley in the shaft

Make sure that the chamfers in the spindle allow you to screw in the two small screws in the direction from the air box towards the engine.

Here's a little trick that I use to get the spring on the pulley very easy. Get a thin piece of wire of any kind and grab the spring, install the pulley and then pull the spring using the wire in order to get it on the pulley indent.





Now, insert the plate in the spindle:



And put the 2 small screws in:



Also, put the aluminum cap back on the side of the TB.

Screw in the nut on the spindle, on top of the pulley. Don't overtighten it! It won't come off!

USE PLENTY OF CARB CLEANER ON THE INSIDE OF THE TB SO THAT NO DIRT OR ANYTHING REMAINS THERE AND GETS SUCKED INTO THE ENGINE :(

Now, make sure that the pulley and shaft + plate spin freely and come back by themselves to rest on the resting screws.

Replace the large o-ring on the TB where it meets the thick plastic pipes and also replace the o-ring on the BBS.

I will post the same thing for the L/H TB soon.

Thanks,
Dan

Now for the left hand side TB ;)

First thing, undo the two screws holding the TBS to the TB.



Gently pull the TPS out of it's place



Here's how it looks on the inside



Now undo the two small screws that hold the plate



Go WOT and get the plate out from the old shaft





Now undo the big nut on the pulley side





Note that there is a slim washer on the shaft, under the not. Don't let that one fall off



Get the shaft out by pressing it with your finger, from the pulley side towards the TPS side; if it's not working with your finger, get it out using a small hammer, but be very gentle!





Note that there is a c-circlip and a washer on the shaft; the circlip has to be renewed, it's in the new kit ;)



Now take the pulley out. It's held by the spring so you may have to de-attach the spring from one side first in order to get the pulley out.







Get the old o-ring out. The new one is provided in the kit. There is an oring only on the pulley side, the one in the TPS side is actually mounted on the TPS and it does not see any action, and it doesn't wear.



Now you will have to take the old bushings out. I didn't do that on this TB because it was OK and didn't need anything, but you can follow the procedure from the post above, the R/H intake, it works just the same.
The only difference is that on this side, one bushing is shorter, 9 mm, unlike the other ones, 12 mm.

After you have removed the old bushings and installed the new ones, it's time to re-assembly everything back as it was.

On the new shaft, install the c-clip and the thick washer like so



Press the shaft into the TB





Don't press it all the way in, only like this, because you won't be able to install the pulley ;)



Put the o-ring on the shaft, it's in the kit



Now, put one plastic bushing on the TB, put the spring, put the other plastic bushing over the spring. Note the spring position



To do things more easy, use the same trick with some wire pulling the spring ;)



You don't have to pull now, just install the wire there ;)

Now it's time to insert the pulley onto the TB





Once you get it in this position, allign the shaft to it, making sure that in rest position, the screws that hold the plate to the shaft can be screwd in the way the air flows from the airbox to the engine.





Now you can press the shaft intop the pulley all the way in.



Get the spring attached to the pulley





Make sure that the spring stays where it's supose to



Now get the plate into the shaft





This would have to be the harders and most time-consuming job, but don't worry, you will be able to get the plate in and the pulley to rest on it's stopping screw ;)

Now, screw the parge nut on the pulley part. Don't over doi it, as it doesn't need to be screwed too hard! It won't come off neighter by itself



Now, make sure that the plate rests on it's stopping screw, go WOT and let the spring do it's job, you should hear that "klank" sound.



Make sure that the TPS looks like this where it meets the TB



You want that part to be alligned with the shaft in the resting position.

Attach the TPS to the TB, just pres it in





Now screw the two screws holding the TPS, but not too tight, as you will be needing to adjust it after mounting the TB to the bike.





And... voila!



Remember that after doing a TB job, you will need to

• sync the bike;
• attach the ground cable if you are doing the L/H side TB;
• also, if the left TB is done, you will need to adjust the TPS; example here
• clean the TB's with plenty of carb cleaner, you don't want any dirt to be sucked into the engine

That's it!

Dan,

I just did my right TB and can't believe how quiet it is now. Instructions were spot on, nice job on the photos. The new shaft and bushings are very tight!

Using the copper wire to remove the busihings worked great. I had to use heat on the aluminum cap side as even with the copper wire tap I couldn't get it to work. Heating the TB helped a lot in getting it out. Also, my aluminum cap was bonded to the TB and it took heat to get it to come loose as well.

Everything worked great, so thanks for the great instructions. Oh yeah, this kit was $100 less than the company kit that made the TB's. Can't believe it would be any better.

Hi Istvan,

I am glad it all worked out fine for you ;)

Thanks,

One added aspect I didn't see mentioned.

When I disassembled my TB's I made sure to match the butterfly plate to the bore. This of course required that the throttle stop screw be 'changed' which leads to a whole nuther level of complication in terms of getting back to the stock setting. So this step may not be worth the extra hassle for most folks.

But if the stop screw has been messed with, then do make sure you tweak the placement of the butterfly plate in the bore. Granted it's not a huge deal but it can affect the wear of the plate on the bore and will help close up the differences between the 2 sides wrt matching their idle settings.

Great a rebuild kit.
I've got a 99 1100 RT, Bing TB's 75/45/105 and 106. have you got a kit for these?

What metal are your bushings made of?, is that the same as the stock bushings?

I live in Wisconsin, USA. I've read that your prices are $60 plus shipping between $13-19. is this correct?
What is the esimated shipping time and how do you take payment?

Thanks,
Travis.
