Hey Todd;
Have you ever tried Sea Foam in your gas tank and/or crancase? It really cleans all the carbon gunk out pronto. A lot cheaper fix than new injectors.
Yup, i've used it. And it helped with the K75. I just never knew for sure what the bike went through with the PO. It was a 94' and when I got it in 08 it only had 9700 miles on it. That's 700 miles a year!!! Definitely was a neglected bike. I read this thread and pulled the trigger.
My swap today was nearly effortless. I swapped the injectors and spark plugs in under and hour.
The bike feels like it has LESS power but my guess is that the power delivery has become much much smoother. One issue I am having is that when I am in 2-5th gear and under 2500 RPM there is a heavy hesitation when I get on the throttle. This was not happening before I swapped the injectors. And all the plugs are gapped the same.
