Here we go some more guys. Yesterday I changed the plugs on my 2000 model K1200LT with 10K miles. I used NGK Iridium DCPR7EIX plugs. I checked the resistance of the wires (which were all in great shape) #1 = 6.34K ohms, #2 = 5.84K ohms, #3 = 6.33K ohms, #4 = 6.52K ohms all of which seem to be within tolerance. I went for a test ride and the miss is still there from about 6500 RPM up. I even tried the "Italian" tune up but had a hard time reaching 8000 RPM. I did not have the guts to try to bounce off the rev limiter. I'm looking for suggestions now as I am somewhat at a loss. I am leaning toward some kind of fuel issue. Can you pull the fuel filter without removing the tank? I also do not have quick connects on the fuel lines but I assume that tank removal is not a common occurence. This bike has the original plastic barbs in the lines, do I need to replace them with metal or just leave them alone?
