I need help before i take it to the dreaded dealer. Its a 2005 4k miles on it missing badly. I changed both coils NGK wires NGK plugs are new. I checked the fuel seems fine. The only problem I'm having is the right rear plug is missing. I'm a car guy and not good with motorcycle terms so don't shot me to hard on it. I'm going to get the battery charged up today and going to check the vacuum lines to make sure there connected properly. Other then that I'm at a lose. I have a friend that use to build custom bikes and he told me to check the vaccum lines on it that might be the problem but he's unable to look at it due to health reason. need help havent riden this bike in 2 years for this problem and due to my own injuries from Iraq and I'm in the riding shape again.
