Hello All -
Just purchased a new FC 350, first time using any sort of air/oil suspension. I know there is a break-in time for suspension, but I'm looking for some recommendations on a baseline to start with. I'm a 190lb C rider. I've read online about setting the air pressure so there's no more than 3 inches of travel from the bottom of the fork and no less than 1.5 inches, but that's about all I know concerning the front forks or even the rear suspension. All help is appreciated - Thanks!

Towards the bottom of the page there is setting. I’ve tried them on my ‘22 KTM 350 and they are a big improvement over the stock settings. Now I’m not saying these are the best settings out there, but they are a much better starting point then stock.

Double check, but most likely your stock shock spring is a 42N/mm. You need to go 1-step up to the 45 N/mm at your weight.

At 190lbs, you might even need a 48 spring.

The forks never work right until you set up the shock!

Thanks! I'll definitely look there to start

That's what I'm concerned with. The manual says the bike is set up for a "standard" weight of 165-187lb. I figured I'm near the top end of that spectrum, so Im considering maybe running the front forks at a higher than stock psi (stock psi is 154 psi) and setting the riding sag a little lower than 105mm to compensate until I get the bike broken in and eventually send the suspension off. I think those adjustments make sense, but anyone feel free to chime in if I have my wires crossed.

Yeah, turn thr 17mm adjuster top of shock in quarter turn at a time as well
