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...

If all else fails, then try a K&N air filter. That should lean it out some.

The Fairing on the 1500 is huge. I couldn't believe the difference when I went from the 1200 to the 1500. The wind has a big effect. Unless it is a moderate to heavy rain, If I'm moving I don't hardly get wet. That air bubble has to be made by something.

Premium can be bad for the motor. It can leave deposits.

I just got a Madstad adjustable windscreen for my 1500. I had a chance for a longer ride this weekend, and got the best mileage the bike has ever done. Real noticeable difference. The thing is the new windscreen is still in the garage, I haven't even opened the box, yet. I sure wasn't expecting that kind of performance.
