Have a ohm meter? Check the pick up. and stator. i was fighting the same issue but thinking i got it figured out i was just real rich never rejetted from winter.
with 20in tires im happy with stock gearing in the trails. Think it mostly depends if your looking for better pull or higher speed to start playing with it.
are they worse then the right one in my pics? Any high temp paint. should be fine just take your time. every one told me mine were beyond cleaning up and did all that in a few hours.

Welcome to BHQ! i used some rust remover and steel wool and some other techniques mostly alot of elbow grease.
well i swapped a coil and seemed to be doing better pull the front end up again gonna go for a ride tomorrow and see if it stays that way or if its cuz i tried another set of new plugs
