Just did a complete motor rebuild mods are t-5 pipes, +4 timing plate, pod filters, stock carbs, 290 mains, 27.5 pilot, needle middle clip, idle screw 2.5, air screw 1.5. Bike started very easy but was idling high so messed with all the screws then I realized I had the carb slides in backwards fixed that. In the morning it fired on the first kick ran well tell about warm up then the left exhaust pretty much died off by half. Right side runs perfect but the left side started running leaner and was blowing cold. I messed with the air screw but didn't help. If I get on the throttle it kind of gets better, Any advice?
Checked caps and switched plug wires still was on the left side. no change. Thinking I need to take the carb off and make sure nothing in blocking the jets or reeds.
