This is what I recommend you do: The next time these symptoms reappear do two things while ridding. Pop the gas cap ( you ll have the key in it ) If that helps you have a venting problem. (No, not your wife bending your ear) My guess is that it won t help. Next engage your choke/enricher. I ll bet the bike will then run much better, pointing to fuel starvation in this particular situation, not others. Have you done the carb vent mod? When I got around to doing that my ride stopped sputtering at high speed. Can t prove it but I think that heat from the sun warming the pavement (never happened on dirt or on cloudy days) somehow kept the original, not vented, carb hose, that lives near the ground, from breathing. Anyway these are easy, simple attempts that can do no harm. Bogdan [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
