Re: Vespa Exhust+air filter+upjett - question
I'm also not sure it's a jet issue, i rode some 16 miles today, mostly at almost full throttle and killed the motor at full throttle at the end of the ride,my plug is almost new and when i took it out it was tan (lighter then milk chocolate) so i dont think it's very lean, should it be darker?
before i had the pipe and filter i took out two rollers to improve acceleration off the line and indeed it was improved.
after the mods it's seems to pull less hard again. how can i tell when is "the right time" for the variator?
