I tried it and ended up trashing the whole thing. It is so much easier to get the yz450f dirtbike needle, main jets and a couple pilots. The needle they supply you with in the dyno jet kit seems like you can't ever find a good position on it.

I have the kit and personally i don't like it. I found no problem in using the needle but the jets are a different story. It only comes with mains and you must use their supplied adapter. Also i'm kind of partial to their jet sizing, i think they go by the size of the jet rather than how much it flows. Kind of easy to throw you off on your jetting.

Alright, STUPID QUESTION, I'm used to a 2-stroke, How exactly do you tell if its too lean, besides the smoke color, by the way it handles/sounds ? Please help, I could tell how it was on my Blaster, but this is different. I probably cant tell if its too rich or to lean cuz its in a good spot. Bone stock 450, about 3-4 hours on it, 93 octance gas, if any of that helps. Thanks alot for any info.
