Another 'trending" discovery, long term parking on sidestand. Within many carb services I'm encountering contaminants (damaging liquid additives as well as varnish) greatly affecting the LH carb moreso than the RH.
I'd suggest long term storage using centerstand (if so equipped) or an appropriate block of wood under sidestand to somewhat (safely) level the bike somewhat. I repeat....FWIW...YMMV.[/QUOTE]
Good info, Gordon........something every "current EX250 owner" should pass along if/when the bike is sold to the next owner.......
