mmm, biggest is a 125 (119 in reality), and then anything that wasnt intended as auto clutch will be missing a certain shaft from the gearshifter that disengages the clutch when shifting.... wtf do you want an auto for? could stroke a postie maybe....
sure you can.. how big did you want to go!?? 450? 1200? itsnto a CHEAP option thats for sure.. its ALOT cheaper and probably eaiser to learn to use a 'standard' clutch.. unless you are handi capped and are missing your left hand.. in which case, adding a second lever to the right hand side may be possible while keeping the front brake. If its a case of having no hands.. I dont suggest riding...
It's for a bike I'm building, sort of cross beetween moto and DH mtb, really want an auto so I can stick to mtb brakes. Have got a 88cc crf motor, but wanted something with a bit more power and 4 speed
For a MTB/Mini Project I think a Honda 88 would work sweet!!!
You wouldnt be needing that much Power and there's a HEAP of upgrades Available for the Honda Engine!
