I have a CRF50 engine in my Z50A and I am not quite sure which transmission to go for.
It will have a TB 108cc V2 head kit with a Taki semi auto clutch
I'm thinking a Honda 4 Spd unit, AHP 4spd or if money allows some type of Taki 5spd

My question is if I decide on the Honda 4 Spd which one is best suited to the crf50 cases?

Also is the AHP worth trying out if I can't find a Honda box?

And lastly if money allows which type of 5sp should I go for?
