Suzuki 2 Strokes

Hello, my ‘66 Suzuki is very strong when first started up, but then loses torque when fully warm. It still screams at mid through high rpm, but low end through mid range torque becomes very weak. Any ideas on what might be going on? Compression is very good, plugs looks good, air filter is clean, bike starts and idles perfectly when warm. This behavior is very consistent by the way, which makes me wonder if it’s normal for this model.

Thanks for your help
Chris
