[dsn_klr650] nklr direct hit

geez, just go to their website and read the technical data. it's appears to
be a peaking capacitor to give a shorter more powerful spark. i'm no
engineer, but i'm reasonably educated, and with a degree in math (proving
things), i can usually spot totally obvious b.s. i perused the website for a
few mins, and decided i should ask my brother (a mechanical engineer who
specializes in internal combustion and emissions issues) about how
installing a peaking capacitor directly over the spark plug would affect the
combustion process. i'll post to the group when i hear back from him.
the tech article by the Sandia Labs guys makes it sound like using the
non-resistor model spark plug is definitely going to give an improved spark
as well (which someone else mentioned earlier on this thread). i
accidentally bought a resistor plug a few months ago, but i'm ready to
change it out now. i'll probably do that tonight based on what i've read
today.

p.s. while it's good to be skeptical about outrageous claims, it's also good
to read and understand what's going on before outright dismissing them. the
direct hits claims don't seem all that outrageous to me, and there may be
some science behind them (at first glance), so i'll withhold judgement until
i hear from a real expert, and the listers who've tried them can make a
longer term report.

Articulated well!
