I recently fitted a leo vince exhaust, OTR air filter, NGK Iridium Tip plug and a power commander V with o2 optimiser and a custom tune from a local dyno shop. The bike was transformed, it no longer sturges so bad at lower rpms and has more power however i feel the ignition system could also benefit with an upgrade, i saw the performance products below and figured they might be worthwhile looking into. has anyone used these yet?
