So I figure it's time to give my '06 hexhead a full break job before summer (now that I have a wife on the pillion to keep safe). Doing some research and reading the excellent BMW Integral ABS Systems Flushing and Bleeding 101 article found on this site (big thanks to those who wrote it), I decided to build my own filling adapter as shown in the article. Unfortunately, doing some research part # 34 51 7 677 998 (the part that adapts the funnel to the ABS module), the local dealer shows that none are in stock in NA or Europe. Checking some other sites, they show them in stock, but are now for sale for $53! That's more than double the original $23 they cost. I think that is ridiculous for a piece of aluminum not much bigger than a couple quarters. Does anybody here have their filling adapter and a caliper handy and is willing to share the dimensions? It should take less than an hour to crank one out on the lathe. That $53 will be better saved towards a new helmet. Thanks.
