im still playing with the idea of a gokart and i have got some ideas on the drive line aswell ,i could use an A12 ,rigid mounted to the chassis and mounted sideways ,with a bellhousing mounted to the motor so the cluth can still be used ,then use a bearing /mount thiat i would then weld to the frame and run a splined rod through it ad weld a sprocket onto it and then slot the splined end into the clutch ,then just run a chain to the bavck wheels

or i could use the motor gearbox and standard diff ,but have the diff mounted straight up to the back of the gear box via the tail shaft yoke and diff yoke ,so there wouldnt be a tailshaft ,just the yokes
and as for steering , i could use a 1000 front end haha ,or i could buy the whole front end from my mates gokart shop

hhmm it could work ,and maybe turbo it !
