hey guys.. ive noticed on my new motor that when I start it and let it run for a few, it smokes more out of the right side and has a bit of fluid coming out of exhaust (im thinking its coolant ) .. so I took carbs,pipes off and preformed a leakdown test.. it held 6 psi til I loosened up the radiator cap, then started bubbling in radiator and loosing pressure.
my question is would this mean a pinched or bad or ring in the noss head ??
