how does this work

Hey i would like to know if anyone has had a problem with the blue wire mod for a 2002 426? also has anyone had a problem with the BK mod?

I have an '01 and have done both of these mods. I thought the blue wire mod didn't really have a noticable affect on starting. It didn't have any negative impact, but I didn't really notice any positive impact either. The bk mod on the other hand did a lot to take away the "yamabog" at low rpm. That being said, I've heard the '02 doesn't need the bk mod as much as the '00 and '01 did. If you are having problems with bogging when you whack the throttle open, I'd say give it a shot. There's nothing to lose and it's easily reversable if you need to.
