[QUOTE="BRush, post: 106506, member: 18729"] Since installing my RB Designs carb, the settings that have worked well are: 155 main, 42 pilot, needle (AEG) on the fourth clip. Air screw 1.5 turns out. Up till now, riding temps have been between 65-72 deg F. The off-idle response has been really crisp. This last weekend, though, the temps got up into the mid-80's and suddenly I'm seeing the rich "gurgle" from just off idle to about 1/3 throttle starting to re-appear. Opening up the air-screw did not seem to help much (but I only made minor changes). I did not really get into it because there's a time for jetting, and a time to just shut-up-and-ride :) My question for you fellow KDX'ers with this mod: Do you find the jetting with the RB Designs modified carb any more, or any less sensitive to temperature changes than an unmodified carb? My seat-of-the-pants opinion was that the stocker is maybe a bit less sensitive. I should also say that I still need to look at the plug and check the reed condition to see that nothing's changed - but it feels like a jetting issue. Also, based on where the 'gurgle' appears I'm trying to decide if it is a needle issue or a pilot jet issue. Any opinions? Thanks. Motor: 225cc big bore kit, w/light porting.
