KLX install no power at half throttle and up
Looking for a little experience as I pull the carb again. Just installed the KLX needle in my 2017. Went with 140 main, 42 pilot, 3rd clip/no shim under (to richen a little for the extra air). Has a UNI filter, snorkel removed, stock exhaust. The rest of the engine is stock. On the test ride, idle up to a 1/3 or 3/5 throttle runs great. After that, the power literally just drops off and the revs barely climb. No power at all from 1/2 throttle up to full open. Maintains speed and sounds fine, but won't accelerate past about 55 mph. No decel pop, nothing weird sounding at all, temp lower than before the KLX needle and at about 1/4 up the gauge.
Even if the 140 is slightly lean for the extra air intake, I wouldn't think it would have such a drastic effect.
I'll take a close look at the diaphragm but it was fine yesterday. Thinking the 142.5 main, 2nd clip on the needle - Unless... anything I need to look for that I could have botched that would cause it to stop revving at about 4000 rpm? I'm comfortable with working on carbs - done plenty but, "you don't know what you don't know."
