I posted this question a while back with no response. I'll try 1 more time. I have an '06 (5500 miles) with a yoshimura 4 into 1, K&N and PC3USB. The bike sat on jonnycheese's dyno and got a custom map. Runs flawless. My question is...75% of the time it starts quickly (under 2 seconds). 25% of the time it seems to take longer (4 seconds or so). Battery is fine and it cranks (turns over) great . Idle is set at 1250. Plugs are new. I've had 3 other Busas that were stock and started within a 1/2 second of cranking. I talked to another guy with an 06 that does the same thing with his PC3 USB and with the stock ECU. Is this an 06 thing...or am I missing something here. thks
