hey guys i just bought this sled brand new and when i stand on it the suspension feels really soft like when i jump on the running boards it squats quite abit. i read somewhere sleds are set for 180lb riders but im 210 ish. how can i set my rear suspension up to harden it abit. its probly a stupid question but i have never adjusted a rear skid before. p.s the front looks to easy to adjust to ask lol
