Im currently having a 4mil built, Im curious about the reliability now.
With my old setup, I never had any issues with reliability,over heating etcc
Its was ported,T5s,stock carbs, +4 timing etc..
New setup
4mil long rod
bigger carbs
+4 timing
155-160 psi
ported cases
T5's or cpi's
I would like to hear from some guys that have a 4mil setups that trail ride and hill climb etc.. and tell me if you have had any issue at all??
thanks joseph
