Okay, have a 250 dual sport, had it running, kick start, but not consistent. CV carb always questionable but is cleaned, really clean.
The spark is not stellar but is consistent.  This is what I'm trying to validate. Have checked valve clearance, specs around 4 to 6 thou, intake and exhaust, meaning they are not hung open. Have a few kick start captures of king set up, shows spark, but what constitutes good? Even did a mickey mouse compression wave to validate timing and ignition are where they are supposed to be.
Has anyone tried getting compression wave (keep in mind, kick starter) so images are convoluted and pressures I get using WSP500 are off the chart. BUT, is you figure in slow crank with a kick it is possible that I could accumulate as high reading.

I'm trying to condemn the CDI, which has spark but not stellar, will drop in what I have, and get a firing line of about 400U, which seems to be congruent with several of my other bikes.

dropping a comparison CDI from 2003 Kawasaki Super Sherpa to look at. CDI signatures look nothing like some automotive. Seems a standard fire time is about 500U, traditional cars 1-2 MS as I recall.

Disected signature of kick start.

Looks okay to me, that burn time is about what you can expect from a lot of CDI type ignition.
