I was looking at the Mikuni / Dynojet comparison chart and maybe I'm interpreting it wrong, but the chart appears to be incorrect. A stock Rappy comes with 140/145 jet set-up. The DYNOJET kit instructions for a stage 2 set up recommends a 144/146 setup below 3000ft w/ slip-on exhaust. If you compare the DYNOJET sizes against the MIKUNI, according to the chart you will be running a lot leaner than stock. This chart doesn't even show a 144/146 on the DYNOJET side.

Besides, you're going to want a richer fuel mixture with the intake & exhaust. According to this chart you would be doing the opposite if you follow the instructions on the DYNOJET KIT. What am I missing here? Is this chart off, are the instructions in the kit incorrect, or am I interpreting this all wrong? I tried going on the DYNOJET link above, but it didn't let me go any further than the main page.
