Hey bhq so the banshee was running tittays in august I mean spot on perfect I had the mains dialed in and she ripped but the last few weeks it all of a sudden got really lean on wide open throttle to the point where it has me worried. since I had 160 mains in during the summer and that is what it liked best I thought maybe just because it cooled off slightly that I just needed to go up a few sizes. Well I'm up to 185 mains and it's still lean when I plug chop. I just did a leakdown test because I figured there must be a leak and it's holding 6 psi like a champ all day long. Is it possible that a leak only occurs when it's hot or when it's under full throttle? Or should the leakdown test have failed if there was any leak? It really hasn't cooled off temperature wise all that much it was probably 85°F in august and now it's maybe 60s here in wisconsin. Does the drop in temp require that much of a jetting change? I didn't think 20 degrees would cause it to lean out that much even with 185 mains compared to 160s... I'm going to keep going up with the mains I just haven't had much experience with temperature changes and how much the mains will differ. Thanks guys for any advice
