Welcome, Canberra-gal! I'm a relatively new born-again rider myself, and although I joined two other BMW-rider fora in addition to this one, the R65 is the only one I read every time I check my email. The others don't even come close to the level of friendliness you'll find here.
You wrote: << I know this may sound stupid but which way is the fuel tap when on. straight down with the long part down?? >>
You showed intelligence by asking a very important question! There have been several BMW fuel petcock styles over time, so if there is a style that differs from what I write, I hope someone will correct me. To operate the bike on its main fuel supply, it's important that the long end of the petcock handle point Down. If it points Up, you're operating on your reserve fuel supply, an arrangement that can complicate your ride making your reserve unavailable when you need it. (If you use your reserve first, you can correct the mistake, but it requires tilting the bike far over to one side—a two-person operation for most riders.)
Unlike you, I showed my own stupidity by not asking your question. Fortunately, I finally figured it out for myself and confirmed my guess shortly afterward when I obtained a copy of the Rider's Handbook for the R45, R65, and R65LS. (The fuel shutoff is covered on page 17, with a photo diagram and text.
If you did not receive a copy of the correct Rider's Handbook with the bike, I recommend that you obtain one. The BMW part number to request is :
01 41 9 798 291 (My version was printed in 1983, if I read the code correctly.)
If you can't find a bound copy, I think that a member of this forum posted a message that an electronic download copy is available (perhaps as a link on this forum; I forget).
if you buy, insist on that part number. Some sellers will try to sell you a later "replacement" covering post-1986 R65s, R80s, and R100s. This is of limited use.
Good luck,
John
