for those in malaysia planning to overhaul their A12... i'll advise not to do so...

change to A15. it costs me about RM600+ for the engine and another RM300+ for the engine transplant and othe misc.

the engine match up with the A12 engine mounting perfectly so no mod jobs needed.

and it is JPJ approvable. (make sure you get your engine from japs not vanettes in malaysia) also get approval to change the engine first before doing the transplant. i found it out the hardway.

do a read up in the internet on water injection. basically it is mixing water vapor to the air/fuel mixture to reduce detonation in high timing engines, cleaning the engine from carbon deposits, reduce fuel consumption, reduce cyclinder temp, and smoothens the engine at high revs
