If you are using port injection and planning to run straight methanol, you
might consider moving the injector location farther away from the intake 
valve.  It doesn't atomize as readily as gasoline or gas/ethanaol blends.
This raw "solvent" (methanol) tends to wash the oil from the top of the
cylinder walls, when it arrives in liquid/droplet form,
resulting in extremely short top ring life.
