I have found that spark plugs can be cleaned -- and sometimes they can't. A shot of brake clean, wipe electrode with a cloth, maybe a few scrapes between the electrode and the groundy thing with sand paper, and check for spark. No spark? Try again. No spark? Pitch em. B8ES spark plugs are a Buck-99 at Advance Auto.
Don't wire brush them!!

Steve,
Maybe I have a bad compression guage but-- now I have three 450's. One with 23K, one with 13K and one with just under 7K.
Warm engine, open throttle, crank over with starter until needle stops climbing.
All right at 100PSI. Both cylinders. The two that are rideable run great! Rip right to red line in all gears. The one with stock gearing struggles in 5TH and can't quite make red line (like all my bikes used to). The one geared lower hit's it no problem.
Wondering how many of us here get my readings or the 180 + PSI readings.
Maybe I need a new guage?
