Hi guys. i’m new to the 2 stroke/carb bikes. i got a yz250 and recently put in a new 8oz flywheel. ever since then i start to notice the bike kinda acts differently. cold starts with chokes revs the bike up super high, bike sounds a little off when it’s cold, deceleration has a little hop to it. With the new flywheel do i have to retune the carb? i adjusted it recently but I don’t think it’s right
