so today i punched it in 3rd an at 5k rpm then needle all of a sudden started going backwards to 4600 or so then back up to 5k and kept going as normal, and i was WOT. I cant see any reason why at WOT it would do that, and it didnt feel like the ignition got cut or anything, it didnt seem like it just lost power and revved down on its own. it almost felt like it pushed itself down, which worried me.

any input on this?
