Thank you very much for the inputs !!
I love this forum, wish I had more knowledge of the Vulcan to help others out too.
I have a black motor, and the caps look fine, I used high quality anodized black hose clamps to hold on the plugs so NP there. Thank you for the info on blocking the vacuum line on carb, I will do that right away. My bike doesn't bang, it just pop pops, and call me crazy but I kinda like it, lol.
Another question please, My bike starts and idles great, but when I take off it seems like it is running on only one cylinder. It misses and sounds like a piece of junk, as soon as I give it gas and get going it feels like the other cylinder kicks in and runs great the whole time I am riding it, no miss at all. Any ideas, could it be because the vacuum line isn't plugged ? Thanks again for the help.
Kawasaki introduced the 750 cc class Vulcan worldwide in 1985. Due to tariff restrictions in the United States on bikes over 700 cc imported from Japan, the initial US spec model was limited to 699 cc. The tariff was lifted in 1986 and the Vulcan went to 749cc.
