Default 2018 XC 300 Power Valve adjustment

Hey everyone,

Been riding an 18 XC 300 for a few months now. I find the motor a little on the weak side. I have it jetted nicely, I followed another members jetting recommendations for sea level and it runs great. Its clean and crisp off idle all the way to redline. The jetting did help the power a bit, but not what I wanted.

I did drop a tooth off the front sprocket, but it's WAY too dramatic of a change on this bike, it feels like it's lost an entire gear (I have dropped a tooth on all my other bikes and not noticed such a drastic difference).

I have been trying to find any information about adjusting the power valve, but the manual has nothing and I can't find any information online in regards to it.

Can someone give me a breakdown on what needs to be done and what you are running for adjustment?

Looking to squeek some more jam out of this thing, I am mostly looking for bottom / mid. I ride alot of trials trails that have really slow speed hits and splatters and need the bike to be more responsive.

Thanks.
