Revivng slumbering motorcycle

If it has more than one karbanator you can pretty much count on needing to sync the karbanators if you remove them from the bike (should be done anyway). Years ago one could purchase "balance sticks" that had Mercury in them. If they are still available....despite how much less $$ they are than a set of Balance Sticks with gauges are....avoid them at all costs. Have seen more than one motorcycle had its motor scattered by the mercury.
