My '68 Cub 125cc conversion uses a manual clutched long stroke engine, the clutch release pull is negligible, enough so that a short, sturdy BMX Bicycle brake lever works fine. removed the old grip and used an NOS Oakley BMX grip cut slightly shorter. Very smooth engagement even with the shorter lever.
I find it's also a lot easier to pull the clutch in to coast for hyper-mileaging on down hills and approaching stop signs. As much as I have liked the semi auto's I've owned in the past, having a manual clutch is a bit more intuitive in traffic and it just seems to shift faster.
