[QUOTE="williamson425, post: 1161705, member: 64854"] 03 yz250f - we just put in a higher compression piston and completely redid the head with new valves, and had the seats machined and all that.. perfect adjustment and so forth. also a jardene (sp?) full pipe put on it. There is a lag if you pop the throttle. We raised the needle one spot bumped the main from 178 to 182 It has a 40 pilot air screw is 2.25 turns out (stock i think) Question is.. would putting a 42 pilot in sound unreasonable ? possibly need a little bigger main as well ? thoughts on needle position. ? Pretty soon we are sending the carb to toyko mods but trying to make it usable for now. [/QUOTE]
