I agree check with King they should have a record, if they dont pull the number off the block and check by that. Or look at your injector harness if its round I believe its 2002 and newer square 2001 and older. Or you can pull the starter number and cross it over to the appropate year. They only used two style starters. One for the earlier years and then of course the later years. And finally pull the number off the CPU and use that as a cross reference. With all that said, I do believe that king only used 2002 and newer busa motors, if that helps.

As for the spark plugs stock NGK's are fine, off the top of my head the are a CR9E. The irdiums are good to but youll never notice a difference in power one way or the other.

And Gene's right about the dyno tuners.....IMO if your just running a k&n, header, and TRE you can use one of the programs that powercommander has on there web site. They wont be setup for the style header you have but will get you really, really, close to what you need.


BTW welcome, And if your intrested in riding with some people let me know, the El Toro group usually rides the dunes at least once a month.
