advancing timing on 75cc gy6 : yes, but you must use premium fuel or detonation will occur

oil seal on crankshaft started leaking = most likely the performance gains were because the oil was originally over full, don't trust the service manual or the dip stick for correct oil level at full. i put in 550cc of oil and it runs best as a rule of thumb

Hy, thanks for anwser.
I use 100octane petrol, that is available on every petrol station in my country. Is this enough?

Ok, thank you for telling me that, i have always putted in 700cc, so the dipstick was on top haha.

Thanks again!
