Have you considered porting your cylinders?

Yes but i dont really have the time right now. I have it torn down right now but the case is still together how much time is it to split the case and put in a 4mil and what other mods will i have to make?

Just to give you an idea this is my motor set-up and I have around 50-55hp...True/welded crank, Wiseco Pro-lite pistons, Agressive trail ported cylinders, Pro-Design cool head w/ 20cc domes, Ported/polished reed cages, Boyesen Dual stage carbon fiber reeds, +4 Timing, Tusk clutch kit w/ 3 HD springs 3 stock springs, Toomey T-5's, Billet water pump impeller.

 

As far as the 4mil. you will need the 4mil. crank of course, wiseco 795 series pistons, your cylinders need to be ported for the 4mil. and you need to have your head domes cut for the 4mil., call Brandon at Wildcard racing he should be able to get it back to you in time.

what if i bought the 4mill crank and put it in without porting the cylinders, and with a stock head or i could buy a coolhead but would it need to be modifiyed
