The truth to your question Steve is no. I know that's been the method many believe is the best way to go but I just don't work that way. We all know the jets and needles overlap and in effect work as a unit, albeit each have their own area of responsibility so to speak.
So I guess I've taken the attitude of trial and error where sometimes I've simply increased the main jet size by one increment, whilst in this case I've nutted it out given the results recently. Of most merit though were some of the comments from others. For instance one comment suggested how it was believed our bikes actually respond better to larger pilot and mid range settings with lower mains in comparison.
For me that required a mind shift of sorts however their is no doubt the butt dyno results speak for themselves and now I'm wanting to know why I didn't go down this route earlier.
In saying all this though, I reserve the right to continue to tweak if I get a poor economy rating or the plugs look scarilly white in a few weeks. Stuff like that. I also really want to get an air fuel ratio gauge which will make jet changing less guess work and much more reliable in the future when I start doing the more serious power improvements.
