Mine has done something similar on a couple rides my ignition relay was fried. Went to a lager one no trouble yet. I was dropping voltage to the coils no misfires on scanner but felt like it was missing all the time.
I stand mine on the front 2 tires and fill with the cap off. Knock on wood one bad radiator cap and that's the only problems 1 year and 10 hard rides with the cooling.
Mark its 50/50 out of the 5 of them i have rode with or worked on 3 jumped out of gear 2 didnt. I will say this after being inside one and in an atlas the stak is a lot tougher of a unit internally. I would equate it to a 205 on the size of the internals.
