    Oil leak

    I have a 1994 r1100rs. It is leaking oil around the oil sensor. do I need to replace the sensor or just the copper o ring? Unless someone else has a suggestion how to get the oil stop leaking thanks in advance.

    The sensor is pretty crappy and it is likely leaking. Fortunately, it is a low pressure to open, normally closed switch and any auto parts place can supply one for a lot less than the BMW OE. They should be able to find one if you have your OE part number as it is used on literally hundreds of different engine makes.

    Thanks Dieselyoda. I order one from Euro Motoelectrics for 12 bucks plan to put it in this weekend. Do I need to dump the oil?

    Well fix oil leak change sensor rode 100 miles no leak. Thought I was in the clear but NOOOOOO....the T section on the front brake lines started to leak.and the front brake quit working. When is it going to stop. New clutch plate,paint work, new tires, rebliud the throttle bodies, valve adjustment and I'm sure other things and now brake lines. I did put barbacks on I'm sure this speed up the process of the brake lines going.bad. Well back to the drawing board and thanks again.

    Likely, never. It happens. We are riding antiques. But, if it was new, would likely be the same, never ending.

    However, they are antiques, there are lost of parts available, you don't need any fancy scan tools or spreadsheets and the knowledge base here combined with the Google and YouTube coupled with patience and cold beer makes every repair you do feel extra good on a ride until you have to repeat.

    Well I want to thank all with the help in this forum . I replace oil sensor, replace brake lines, clutch plate, valve adjustment, sync throttle bodies,tires, fluid & oil any other things I cannot think of at this moment. Is there anything else I need to do? Since I got this done the bike is a pleasure to ride. Should I be good for a while or is there something else I am missing?

    One thing I did to my R1100r is buy the newer 1200 fuel injectors, the performance improvement was noticeable, and for the price, well worth it.

    Fuel injectors

    I don`t believe I am going to ask this but I can`t resist spending more $ on this $1500.00 motorcycle. Which injector is better the Tills from Germany or the ones from the Euro Motoelectrics?
