piaggio zip 50 problems judders plz helpppppppp?
hiya there
my piaggio zip 51 plate starts up on the button, however when you try to rev the bike it ill rev up but judder through the revs, as though the engine is maxin out then droppin revs and maxin out again, it will gather speed but the engine will continue juddering as it does so.
i've taken the carb off cleaned the jets, all the surrounding areas, all inlets, changed the rollers, varitaor, i've even changed the spark plug twice, i also took off the carb and sprayed carb cleaner directly into the engine , the engine started but was still juddering, there is no loss of power or any cutting out, could anyone help
