Hey guys. My son has a 2014 crf125f big wheel. Cool bike. All of a sudden he's having trouble wit it bogging down. It idles fine, but under a load it bogs and he has to flutter the throttle like crazy to keep it running. We took the tank off and cleaned it, it looked fine. Took the carb apart, looked clean and fine. The ignition key casing is cracked so we have a new one on order. We're thinking of upgrading the carb in hopes of fixing the problem, as we can't figure out what is wrong. Looking forward to hearing any ideas on how to fix, or carb recommendations. Thanks
