Stem Mounted Sat Nav

Hi


I am going abroad next month on the bike, so this is the start of sorting a few things out. I am hoping to buy and fit one of these:

http://www.ebay.co.uk/itm/1508272647...84.m1423.l2649

However after removing the stem cover I have found a tin plate in the way. I was unable to get a tool up from the bottom of the steering stem to try and knock the plate out! Has any one got any ideas or suggestions please.

Regards

Mark

Posted a pic in the gallery of a GPS mount I fabricated with 1" (cut 1/4" long) aluminum pipe and a Ram ball mount. I cut the ball mount to fit inside the pipe. A little polishing and some epoxy and it came out well.

Send me a PM with your email and I'll send the pic along with instructions. Cost is about $10 with a little elbow grease.

Thanks for the tips, BUT something is bugging me and the pictures in the gallery could not give me an answer.

It is clear hot-to fix the ball-mount to the short pipe, BUT HOW does the pipe hold into the triple-clamp (I see the cap was removed). Has the pipe been threaded or is glued there ?

Any help or more pictures would be greatly appreciated.

Stem Mount Help

Crowinthehouse has sent me a PM with a cheap home made alternative . However I am still unsure how I can insert anything into the stem. I have prised the BMW roundel off but underneath there is a tin plate, as anyone got any ideas as to how to remove this plate?

Thanks in anticipation

What you are seeing under that cap is the bottom threaded end of the top-bridge Ball-Joint (see attached picture - red arrrow). This cannot be removed.

The BMW Telelever front fork do not use conventional ball-bearings (or tapered bearings) in the steering. Instead, there is a ball-joint attached to BOTH the Upper AND Lower fork bridge. On the k1200RS, both ball joints have the same part number - the upper one is installed "upside down" compare to the lower fork bridge.

This is why I posted a question in this thead to see how he did attached his pipe (or tube). There is not much room there under that cap ?? Hopefully we will get more pictures.

P.S.: Thank you for the PM.

Sorry, I should have been clearer about how to mount my home made unit. I had originally bought a RAM stem type mount before knowing the info shown in Sailor's pic. I realized I couldn't use the expanding type mount (the one you had a link to earlier in this thread) on the open center tubes you would find on the japanese bikes because of the telelever setup on my RS.
The unit I made up is epoxied to the top of the center cap (roundel removed) with VG quality epoxy. The aluminum ring is a 3mm slice of aluminum pipe with a 25mm ID. With a little polishing the aluminum looks as polished as the cap. I trimmed a RAM plastic mount (Stock # RPR-351-WBB-F $2.95) to fit inside the aluminum pipe and epoxied it in. After the epoxy dried, I sanded the base perfectly flat and then epoxied it to the cap.
It still allows me to remove the cap if I ever need to and is a very solid mount for my GPS. Second year for it and some bumpy roads and not a problem yet. My 'cheap' alternative cost me $3 and about an hour's worth of my time and I think looks better than the unit you bolt onto the clutch or brake reservoir.
