Hey ?? Droptine? (Many of us use real names there - we're a pretty friendly bunch..)
Please take a look at:
http://www.bmwmoa.org/forum/showthread.php?46055 - I'm sure you can understand why the answer to your question isn't necessarily a universal one, so model/year would be good info to put in the thread title. I'm going to add it to the thread title in the hope that someone who owns the same bike and has BTDT will open the thread and provide an answer. Please do that yourself in any future threads you start in the tech forums. Helps you, helps others who may be looking for the same info later on.
Welcome again - and what'cha name?
