Thanks for the offer, Opus
Maybe the K&N filter with its hex head is not such a bad idea. No special filter wrench needed. Just use a 17mm wrench.
Using Open Office makes it incredibly easy to save something as a PDF file. Like I said earllier, I want to see about finding a local source for a crush washer and O ring also. On top of that, I have a BMW part number that I understand is for an automobile but will fit the brick. I need to check that out too.
Any ideas of what else you would like to see on the list?
