    i have a 70cc yamaha neos - it used to go 60-65mph.
    it was running poorly and stalling, so i took it to the shop - where they replaced the fuel lines and cleaned the carb. now it runs nicely but i cant get over 35mph

    the revs picked up loads down a small hill and i was able to go 40mph+ but on flat it goes nowhere.

    on the centre stand it eisily gets to high revs but when im sat on it it hardly revs at all..

    rollers are light - 3.0g
    i tried 4.5 g rollers but still same problem, it just got to 35 a lot slower.

    and help anyone?
    i want my scoot to go fast again

    If you took it to a shop and now it doesnt work as it should then take it back and get them to sort it.

    yes, but the garage dont know what is wrong with it so they cant attempt to repair it...

    could it be a jetting issue?
