Hi I am new to this forum, after purchasing my first BMW k bike. I bought a project that seems to be having fuel issues. I'm not really sure what my next step is at this point so I figured I'd see if anybody has had similar issues. When I bought the bike, it would idle fine, but it would stall when I would give it a little gas. The previous owner had replaced the fuel pump and said he cleaned the injectors. I just replaced the fuel filter, air filter, spark plugs, checked the valve clearance, and cleaned out the gas tank(there was a lot of gunk in there). I went to start it but unfortunately it did not improve. Actually, for some reason it didn't want to idle at all now and would just run for a few seconds and stall. I really appreciate any help as this is becoming frustrating. Thank you!
