rode a 100 miles, bike sat 3hrs. started fine, then started missing, can feel it inright exaust. put in seafoam, idled it as low as possible for ten minutes, no help. changed plugs also.

Maybe a bad plug wire or coil? Are your valves adjusted correctly and not too tight holding one off its seat?
Good luck,

When you rev the engine does it still miss or only at idle?
