I had both of mine replaced on the ‘05 at the dealer at around 50k. It wasn’t cheap.

You don't have a lot of choices, 'Beamer Bits' is not nearly as expensive as buying new throttle bodies from BMW.  Used throttle bodies from E-Bay is a big crap shoot with a large number having cracks, you can try Bing USA as they will install new plastic cams or full cams/shafts but (personally) I'm not enthused with how they re-time the base idle screw settings.

 

You can buy the parts from Bing USA cams-on-new-shafts, then install them yourself but that is a bit fiddly with some basic mechanical knowledge involved. 

 

Here is a write up that I did a while back on installing the cams/shafts yourself with re-setting the base idle screws.

Here are the shafts with cams already installed__ (link below)

 

Your screws should be re-usable, same with the clips if you have the proper tool to remove them, the cap is a bit difficult to remove so maybe buy a new cap just in case (all the caps I have removed have all been removable without damage but it can be a bit tricky). Probably don't need plastic bushings  but yours might be worn a little.

Are these improved parts or same crappy plastic will eventually break design?

 

Making me want to remove my tupperware to have a look.

 

Any special cover to remove or should this cracked area be visually accessible once plastic is off?

Take all the plastic off a light and a mirror and you can see them very easily,go to utube and look up max bmw they have a video that shows you how to remove the plastic.

The ones that I have installed looked to be exactly the same as the originals. I haven't seen any of the replacements break but none that I have installed have many years on them yet. 

 

Once you get access to the throttle bodies you need to slide the plastic covers (the covers that cover the  throttle body cams)  up the throttle cables to uncover the throttle cams, then use a small mirror & strong light to view the throttle cams.

 

There are mold lines on the plastic cams so don't confuse those with cracks.

Afternoon Bigfish

 

Nothing confirmed but from my past experiences it seems to be more of a time period & number of engine heating & cooling cycles  than actual miles traveled.  

 

I did a 2009 1200rt last fall that only had 13,000  miles on it. On side with a little crack & the other side with 2 large cracks.

Best advice on removing the throttle bodies is to get the correct pliers to remove the clamps on the TB boots. (very easy to damage the clamps if wrong tool is used)

 

If you try to pry or use the incorrect tool there is great chance that you will distort the clamps or bend the clamp retention area tits then you end up with loose or leaking clamps, or worse they snap open while riding. 

 

Be very careful in removing the throttle cables so you don't break the cable adjuster barrels at TB bracket.

 

Your can leave the TB boots connected to the cyl heads & air box  then pull/work the TB's out of the rubber boots & off the bike. 

 

When re-installing the TB's  don't forget to install the plastic covers on the throttle cables BEFORE installing the cables into the throttle bodies. 

 

Above all-- if something doesn't seem right or feel right then STOP & understand why that is happening before proceeding.

That clip is to retain the throttle cable adjuster.

Nothing special or extreme, sometimes the cable will just pull out of the clip with a little tug & on others you need use a small screwdriver to reach in & deflect the clip a little.

 

Just don't force it (be gentle),  use common sense. 

 

Don't forget to remove the throttle cable from the TB cam before pulling the cable out  (you can rotate the big TB cam against the spring in the open direction then work the cable barrel out of the hole with the cable coming out through the cam slot.

No link but you can search for them on line, just search for (CV joint earless boot clamp pliers).

 

You can usually buy or even rent or borrow CV joint earless boot clamp pliers from a local auto parts store as those low profile boot clamp pliers are used on automotive front wheel drive low profile axle boot clamps.
