hey any opinion is welcome pleasse continue.
thats exactly what I'm going to do
i would put the 5k in but the problem is that i wont be able to find such engine in israel so thats a problem for me
how much (about)HP the 4 k will produce with such tuning and how much the 5k?
i mean with twin carbs camshaft,some port work and maybe just maybe balance the crank shft to go higher than 8.?
