Bmw R1100 and R1150 Throttle Body Synchronization

The BMW Guy

In this video, I walk you through how to perform a throttle body synchronization on a BMW R1150 Oilhead. If your BMW R1150 has a rough idle, excessive vibration, poor throttle response, surging, or doesn’t feel like it is running smoothly, properly synchronizing the throttle bodies can make a huge difference.

This BMW throttle body sync procedure applies to the entire BMW Oilhead family, including the BMW R1100 and R1150 models. The same basic process can be used on the R1100GS, R1100RT, R1100RS, R1100R, R1150GS, R1150GSA, R1150RT, R1150RS, R1150R, and other BMW air/oil-cooled boxer motorcycles equipped with the Oilhead engine.

We’ll cover the basics of BMW R1150 throttle body synchronization, including how the two throttle bodies work together, why synchronization is important, and how to adjust the throttle cables and throttle bodies correctly. I’ll walk through the procedure step-by-step so you can understand exactly what you’re adjusting and why.

A proper BMW Oilhead throttle body sync helps both cylinders pull evenly and can improve idle quality, throttle response, smoothness, and overall engine performance. This is one of the important maintenance procedures to understand if you own an older BMW boxer motorcycle.

Whether you’re searching for how to sync throttle bodies on a BMW R1150, BMW R1150 rough idle fix, BMW Oilhead maintenance, BMW R1150 throttle body adjustment, BMW R1100 throttle body sync, or BMW motorcycle throttle synchronization, this video will walk you through the process.

This procedure is commonly performed using a vacuum synchronization tool such as a Digisync, TwinMax, CarbTune, or manometer, depending on what equipment you have available.

It’s kind of crazy that these bikes are still relevant today, even though my R1100RT is about to turn exactly 30 years old and I still ride it every day. Thanks for the video!

This video breathes new life to countless R850, R1100 and R1150 given they're 25+ years old now. This is a great help to DIY owners like me who love to learn and work on our bikes. Not knowing how to go about or where and what to look for, this step-by-step guide is a godsend. I'll seek your help through the premium services you offer when I start working on my R1150R. A BIG thank you!

So glad I found your channel, I’m sure both my R1150R and my wallet will strongly agree.

I did this on my R1150R and the difference was spectacular. My fuel economy was spectacular too. 70 mpg at motorway speeds plus some cross country.

Dude i cannot thank you enough for your videos.

I am new to these bikes and even the bmw dealer "can't help" with anything.

These videos are a life saver

Last year I acquired a K1 with a missing throttle body, among other fun things. Fast forward, I sourced a throttle body and tps and have her up and running, but desperately need to do this procedure. Needless to say all of the inked factory settings are in need of adjustment as well.

You have to check the hall sensor position first from factory it not on the good position than the tps than than the tps on 400 milivolts

How does one know what values are the right ones, and which ones to adjust?

Are we supposed to warm the bike up to operating temperature ?

Hi BMW guy,

I’ve got a question/comment/tip😉 – not about this video, but I don’t know where else to ask😃. You’ve made several videos about your wife’s BMW, but why do they all have different titles? There’s one called “She wanted a vintage motorbike. R75/5 Pt2”, so shouldn’t the others be called “She wanted a vintage motorbike. r75/5 Pt1” and “She wanted a vintage motorbike. r75/5 Pt3” and so on? Because at the moment it’s difficult to find the videos that go with your wife’s BMW and get them in the right order 😀

sounds like it needs new rocker pushrods too?

I definitely touched those screws. What have I done?

What's with the unskippable ads?

@alanoswin8827 3 weeks ago

Been through this way too many times, i know the throttle stop screws were adjusted by a previous owner, id be very interested in you doing a video on how to set the said screws, and what software do you use for the tps set thanks.
