hi all, im needing some info on the zx12.

following on from my failed clutch basket on my A1 engine, does anyone know if the baskets were uprated in the later engines? I know the oiling was improved but my concern is in the actual strength of the basket. Im trying to source a billet basket but this is proving difficult

my next question is, which other years of engine (if any) will be a drop in replacement for my faulty A1 ie will a 'B' block and head run with my A1 throttles and wiring loom?


thanks
