    Hey guys. I bought a 2011 WR300 for my son a while ago. I have a WR300 myself but i use thye PWK carb in that one. I have forgot what needle could be good to use in the summer in the Mikuni carb. I feel that the GAY needle is too rich at the base diameter and the bike bludders on light throttle so i need to have a better option there. What do you guys suggest? I know thye GAY needle is quite lean in the middle so maybe a tad richer there too. Any ideas?

    It's not just the needle that is the problem on this bike. The needle jet is also a bit too lean. I bought the JD Jetting kit, that has a richer needle jet, a lean needle and a rich needle, plus a few pilot and main jets. There is enough stuff in that kit to get the bike dialed in for any situation.

    Try DEY or BFY. Or try the JD kit.

    I would argue that it's not the needle jet that is the problem, it's the needle. the JD kit just uses a different needle jet so they can use an existing needle they already make. Fuel only cares about the gap, not the diameter.
