Re: what did you do to your motor bike today? Hey Dan, have you thought of using a screw jack type of device similar to what the SBP shift kit uses? Visually speaking, it would blend in seamlessly into the motor mount/ bike. As for the improvement it the engine's performance, I don't know for sure. What are the chances that the original spark plug cap had a poor connection to the spark plug wire? Or perhaps from the cap to the thread on spark plug nipple?
