Piggy backing off what he said smell your oil and if it smells like gas DO NOT let it run until you change oil immedity!!! I would jus put cheap 10-40w in it until you get it figured out so your not wasting good oil and money trust me I jus wasted 4 quarts of royal purple max cycle that stuff is 16$ a'quart and I had to throw it away. I didn't tho I'm gonna use it for lubing stuff up but still a WASTE. like o said don't run it if it does or you could destroy the timing chain along with that the motor as well unless you get lucky


QUOTE=sjona2011;1303261]do you have a multimeter? if not buy one and check the resistance of your coils and plug wires. it seems that its still dropping a cylinder when you rev it. has it been jetted? pull the plugs back out and see what they look like. it might be running way too rich.[/QUOTE]
