Bad sparkplug?

new spark plugs used for the testing, they checked good, just bought the bike, been sitting outside for 6 years, the off/on switch, I believe kills power to the points, but I have power coming out of the points to the coils, need to check the coils I guess to see if they are good

how about your plug caps?  NGK makes real nice ones for a few bucks apiece.  You might also check to see if your plug caps are screwed in well.  I understand the end of the wire can get mucked up so "dressing up" the end of the wire is sometimes necessary.  Unscrew the plug cap, cut 1/4" off the end of the wire, then screw in the cap again.
