POP....needle vs jet change???
Posted June 27, 2005 - 02:17 PM
So, is there an online tutorial that someone can point me to that describes jetting in detail? Like what does a lean or rich needle feel like compared to a lean or rich main? Something that explains the symptoms and what to do and how to check things.

I'd definitely bump the pilot like Indy recc'd and if it were me I'd up the main to 165.
I'm running a red #4, 170M here in TX
500 asl & HOTTTT

Why did you disconnect your AC pump! It is a pumper carb and works better with it! The ACV circuit is another thing which some guys do bypass and go to a leaner pilot but it is not needed on a WR450 to get her jetted right. Have you got a 48 pilot jet in her and an adjustable fuel screw.
Indy, I just DC´d the thing to see if that was what was causing the bog, just a diagnostic measure. From that I learned that it was not causing my low end falter. Now it´s back in place. Affirmative on the fuel screw, but the pilot I never even looked at. I was under the mistaken notion that this JD kit was sufficient under all normal circumstances, and I never even looked at my pilot number(im sure it´s stock 99) Frankly, I feel JD´s needles may indeed be the best you can get, but beyond that the the info in his instructions is about nill. Beyond his initial recomendations, there is NO info on which way to turn when things dont go right the first time around. Did not help that he did not seem inclined to answer any of my emails, hope he´s on vacation. Oh, INdy, mines a 99, so no ACV right?
Maybe he meant he disconnected the TPS?

Bronze, yes I did really mean the AC pump, but yes my TPS is currently DC´d as well. My main is close now at 160. The humidity here (I think) is much higher than it is in Texas, that and I´m running a PMB insert which is fairly restrictive makes me think that the 160 is just about right. But right now there are more pressing issues like what causes this little hesitation on cracking the throttle. I´m at red 3 now, and Indy recomended red 4 three days ago, I gotta try that. Also, a Taffy quicky comming up.
Hey thanks for all the feedback guys, owning this thing down here would be WAY more difficult without this forum of extreme coolness.
