dont know i bought it complete,and i dont thing its ported
196/128 is what i got when i degreed it
the crank looks new and i know the pistons are new because they where replaced right be i got it.....and ive only ran the maybe 4 times
its a good motor,i just want something smaller
this motor is worth way more...the crank alone is $1400+ which is a billte crank works crank,im just trying to get some thing smaller
