    theres no power for about 5 seconds
    i had it out for a ride today running a 90 jet and open filter
    i took it to the shop turned it off

    av u blanked the vacuum inlet where the reeds sit? i hav blanked mine off seemed 2 run alot better :pimp: and i am using the vacuum on my carb. think the 1 i blanked off is for the fuel pump on the runner. so not needed.

    Too rich on the air screw, adjust it or fit a smaller pilot jet.

    waterproof air filter
    straight inlet
