Yeah that's problematic. A 500cc track bike I had came with primitive slide carburetors lacking any sort of accelerator pump by design. Cold or hot that thing

Yeah that's problematic. A 500cc track bike I had came with primitive slide carburetors lacking any sort of accelerator pump by design. Cold or hot that thing would fall on its face if you were too ham-fisted with the throttle at low RPMs. But at least it was deterministic at this, and you quickly learned to not do that. On the track you're never down so low in RPMs so maybe it even made sense from a KISS perspective.
