I made this little review after rebuilding my motor, and with a new single PJ34 carb installed.
My mods are:
Mild ported, 66mm prox pistons (370cc), stock stroke, +5 degree key, head mods (160psi), cylinders lifted 0.4mm (with an extra base gasket). Ported reed cages with carbon reeds. Trinity intake with PJ34 single carb, clamp on Uni air filter. 182 main, 52 pilot, needle in the middle. Maxima Castor 927 mixed at 30:1 with 100 octane gas
