Was thinking of selling my 400 and getting a two stroke. Riding around Elsinore today changed my mind. You roll up on someone (who's)on a two stroke and they freak out (not everyone) I LOVE IT! They hear you coming, start rubber-necking,then slide off or pull over. The sound of the thumper scares the piss out of them. Then they get sandblasted by your roost.Was laughing so hard I had to pull off of the track. May still sell the 400, but won't buy a two stroke!
