Seems like a much better investment than an after market pipe. Decent torque and horsepower gains with no trade-offs.

port and polishing is a sensitive issue and in Thailand it is hard to find someone reliable on this unfortunately and honda shops refuse to do mods here as well.((
any advices?

if you are here, i can do it for you.
we do have custom camshaft long duration and custom head with bigger valve.
but for regular customer, we only move(dial) timing valve.

we are not using 44mm THB yet. usually we do reamering inside THB diameter and change the butterfly.
