    I have had some trouble with the bike i took it up to bristol yesterday and as soon as i got to 70/80 mph it started to slow down when the throttle was fully open up it would lose power on the uphill but having pulled over and gave it a rest it was good to go again untill i got to the same speed and then it would do it all over again it sucked lots so i need to get her fixed anyone help???

    Check fuel flow from tank to pump.

    If you removed the vaccum slides, there is a possibility that one or more diaphrams are misaligned or pinched, so the slides don't rise to enrichen the fuel/air mixture.
