SV rpm fluctuations

[dabear]

When going full throttle on the engine the rpm fluctuates 200-300 rpm. I have the recommended resistersinplace on the mag switch connections. I recall a recommendation to a similar issue but dont remember the fix. How high should we go on the resistor?

Anecdotally, 60k to 150k seems to be the range that tends to help. Eventually you'll actually stomp on the actual signal and will start loosing pulsses. So you can go maybe 60k ish, then 100k ish, etc etc.
