At the Brimstone ride I found my spark pug cap was bad and at the time I did not know it was replaceable so I ordered a cheap coil off amazon and this week I found it to had done went bad. Not wanting to go through this again I purchased an AMR Racing coil (which does not come with a spark plug cap) along with an NGK spark plug cap and installed them today..
By the way the stock spark plug cap threads off counter clockwise and the new one threads on clockwise..
