Ok, I did the dave carb mod (slide drilled, needle shimmed 26k, 55 short pilot, 158 main, idle mix tab removed and 2 1/4 out) and it made a huge difference in the midrange power, driveability and overall performance. But I still have a slight bog right off idle. Bike is a 01 XR650L at sea level with snorkle removed, K&N filter, big tube header, W/B e-series with 8 discs, IMS desmogger and the canister removed. Single vacuum hose from the diaphram on the right side of the carb to the port on the front of the carb. I did some searching and found a similar combination that is using 58 pilot and a 162 main. Anyone else have a similar combination and care to share some jet recommendations? Thanks in advance for any help.
