I've considered trying a +4 or +6 trigger wheel in my '93. I once heard somewhere and found adding an extra degree advance / 1000 ft altitude helps. Since the majority of my driving/riding is at 5000' + the 6 degree wheel may be the ticket. Both the car and Jeep seem to like timing set +5 from factory spec here in Denver, and neither one pings at low altitude either.
If I found the bike pinging at low altitude could always bump up to the next grade of fuel...
