I plan on buying an MR-12 and then having it ported for $60. Will that be equivalent to the hand moded MR-12? I have about $200
nope, a ported MR-12 wont even come close to a hand modded MR-12
when u buy a hand modded MR-12, almost everything is modified to the maxium ROAR specs
talk to Maverick Racer about it
quoted from him
"Any ported motor that you buy will have the following done.
New crank port timing.
New crank face scoops
Piston skirt on transfer & boost side is cut
Boost port opened & re-angled
Transfer ports re-angled, widened & outside of sleeve is worked.
Exhaust port is taken to the Roar limit, 4.5mm and polished.
Piston crown and top of sleeve are re-polished and honed.
Backplate is relived below the transfer area.
Head bubble is reshaped
Head deck is reset to tuners spec"
"expect to pay between $220-300.
Here is a good list of well repected motor tuners and what they build:
Richey (mugen, rb, colari)
DWR (me) (mugen, sirio, rb)
Smelts (rossi, mugen, os, sirio)
Murnan (mugen, sirio)
Pat Fox (rb)"
my bad about the price it's around $220-$300(including the engine)
