Hey everyone! So a couple of weeks ago I was riding my 1994 K1100RS and it started to feel a bit laggy when hitting the the throttle. Rode a couple minutes back home and at that point it wouldn’t get up in the rpm’s and hardly had any power anymore. Struggled to get it to 55mph. So I replaced the intake boots and o rings where the intakes bolt to the engine, as well as the injector o rings, thinking maybe an air leak. Sanded and cleaned grounds, blew air through the fuel lines, replaced fuel filter and lines in tank. Tested fuel pump and it still has tons of pressure, and new spark plugs. Yet still, the delayed throttle response off idle, and at full throttle it almost sounds as if it’s running on 2 cylinders? Thinking at this point it could be a spark issue? Hoping to get you guys’ thoughts before dumping anymore money into this thing. Thank you very much!
