First post on TT. I have an '01 426 that I recently cleaned the air filter on and changed the oil as well. I noticed the day after I changed the oil that I left the gas on after the test ride. I've been around bikes quite a bit but this one is stumping me. The bike will rev cleanly in neutral but will sputter and miss when shifting through the gears. This is my first modern 4 stroke and I could use some tips. Full synthetic oil or semi? Any help would be appreciated. yasotay Go that way real fast, if something gets in your way, turn.
