Year: 2003
Pipe: T4
Filter: K&N no filter box mods
Main jets: 145/150
Pilots: stock
Needle position: ummmmm I forget...I changed one way from stock not sure which way [img]i/expressions/face-icon-small-wink.gif[/img]
Elevation: sea level (jersey maybe a few hundred feet if that)
Crankcase Oil type: Yamalube 4

prob gonna change the mains to run a little richer for the winter time and cold air. I was jetted when it was like 110 out so it might be a little lean now that it is getting colder. Im getting popping on decel now so that is one sign of leaness now...
