  1. k so i did a bunch of searching and came up with a few ideas but i was hoping someone could give me an opinion.

    my motor runs great sometimes. other times not so much. most of the problems peoiple have that i have seen arent intermittent or occasional issues. some days i can hop on my chopper and wind out to the point i have to slow down for the 50kmh speed limit and other days it bogs out to the point im lucky to get 35-40 kmh and have to play with the throttle. i also noticed some oil leaking(looks like the bottom of the jug) i have to tighten my head bolts a quarter turn with the ratchet every couple rides. im thinking of plaining the head and replacing the head gasket but im iffy about it because as i said some days she runs perfect. also thinking of using a small amount of gasket maker between the carb and the intake manifold. any other ideas? its a skyhawk 5a 66cc running 100ml of oil to 3 l of gas. starts up no problem and has plenty of bottom end power. its almost like my power band effs off some days

    head gasket not tightening usually means the acorn nuts are binding on top of the studs - easy fix is to break the caps off so nut can go down farther
