Need suggestions for more bottom hit

[preston953]

I have a 2018 250 XC with a FMF Gnarly pipe and I'm a little disappointed with the bottom end response. Has anyone experimented with a Smart Carb on their GG bike? I'm also open to moving around the setting for the exhaust valve or getting a head mod. I just need/want a little more hit off the bottom to loft the front wheel over logs, ditches and trail obstacles.

Start with playing with the pv adjuster since thats free. The Rk tek gave my 300 more power across the board. Or your other option is buying a 300 top end and bolting it on.

Put a 51 tooth rear sproket set the squish band play with different jetting I like jd jet kit and check power valve setting it will rip then

I agree with the previous comments and will add that the STIC metering block will make a great change across the board.

Thanks for the suggestions gentlemen, much appreciated.

Since I want a little more bottom hit. When I adjust the exhaust valve, I'll want to decrease the pre-load so it opens sooner, correct? So that will be a counter-clockwise adjustment (lefty loosy). What is the stock setting, 2 turns out from closed? What is the suggested turn increments, 1/4, 1/2 or a full turn?
