OK guys, I've asked Dinqua about this, looking for some ideas how to minimize or eliminate a slight occasional surging I notice at around 50-60mph (in 4th or 5th gears). Maybe it's always been there since 50-60 has always been where I notice the most vibration, but if I am cruising at a steady speed around 50-60, it seems like the bike surges back and forth, more noticeable downhill. Also a little under hard acceleration. What do you guys think? Anybody else out there see this. Have 130 Mains, 42 Pilots, 1 Shim on stock needles, Bub Slash Cuts and all Snorkels removed with a Unifilter.
