90 Big Bear - High RPM Miss


My fathers new to him 90 350 Big Bear has a high RPM miss and fouls plugs. Any ideas of where to look?

have you clened/checked the air filter?

i have a clymers for that bike if you need some specs.

Air filter is new. Does the Clymer manual have ohm checks for the ignition coil and magneto.

sry been away. i will check for you.

It is probably from a weak spark.

New plug installed. No change
