I just installed a new iridium plug that I bought from NAPA (NGK 6681). At first I gapped it closer to .7mm and I had difficulty getting it started and when it idled, the exhaust smelled rich. As I revved it up it would sputter and cut out around 4k. I pulled the plug and regapped it to .025" (.635 mm) put it back in and it ran great. Idle seems much smoother than stock. It revved up higher, smoother, and faster than the stock. I've only been testing it on my swingarm stand and haven't had a chance to take it out on the street yet as it is raining here in CA.
Next goal is a conical filter and sigma6 rejet kit.
