I have a new to me 76 R75/6 I have owned for about a month. I have been working out bugs snce I got it, the bike sat for about 1 year after it was supposed to be gone thru by BMW servce center. Recently when I start it in the morning it does not seem to have any power until it get good and hot. Yesterday on the highway it did not seem to have any power at around 70 mph. It actually would seem to loose power when I tried to open it up and it did back fire as it boged down, I could barley keep up with traific on steep inclines at 65-70 MPH. I tried to open it up to see if it would accelerate and it just could not go faster than about 70. It feels kinda like it is only running on 1 cylinder.
How can I tell if this is a fuel issue, a compression issue or a spark issue. This is my second BMW and my first classic air head but so far this bike has been a great disappointment. The bike is in great condition and looks very nice but so far I have had to work on it every week t try and work out the bugs especially with the carbs. The service center did help get the carb issues worked out, at least I think so. I am not sure they are right still. Appreciate any help I can get. thanks randy
