I just recently bought a used 2017 KTM 150sx and have ran into some issues that I think is not normal for this bike, it kick starts on first kick and idles perfectly but what I'v noticed is that in 1st and 2nd gear it seems to almost hit a rev limiter and never engage the power-valve is this normal for these bikes.It does hit the power-valve in the later gearing but from my understanding it should hit it in every gear at a certain RPM. I'v cleaned the carb and checked the reed valve plus the jetting is set to stock. The altitude here is 400ft above sea level..Compression was good in the top end as well and new gas was used too. Carb specs- IJ=45, needle=43-74,needle pos=3, MJ=470 Any ideas out there on further troubleshooting this?
If that moves freely, check the reeds for gaps. If you hold them up to light and there's light shining through, that could cause many power problems.

Overcomes the problem of sticking power valves fits the 150sx as well.
