When I bought the bike I ran the 85 as suggested. Tried the high test, just makes the de-cell pop worse, and makes more black sooty exhausts. Went back to midgrade, and sticking with that. De-cell pop isn't too bad at 5000-6000 ft level, but get a lot of bang going over the passes at higher altitudes.

Tried looping the two lines on the smog back into each other, and that took care of the popping, but make the carb cough on throttle flips, so put the smog lines back on, and live with the deceleration backfires when I go up over wolf creek pass, or up to silverton. Those 10,000- 14,000 ft passes and just live with it.

Try to get gas at the stations that advertise a techron additive, and that always makes my dodge truck run well. If I try another brand of gas in it, man does it ping, and knock going up hills. But hey, thats a dodge for you.

One guy wanted me to go with one number hotter on the 4 plugs but will stick with the OEM plugs. They are showing a clean burn with no other signs of problems.
