when i accelerate from gear 1 - 2 it seems to misfire before i go anywhere does anyone know any way of solving this or what has gone wrong? thank you in advance

Are you slowly increasing the throttle, or wazzing it open and expecting a powerful and immediate response?

If the former, start by checking your plugs. If they're fine, then your engine is possibly running a little rich and the misfire is too much fuel in the system. Try adjusting the mixture screw on the carbs.

If the latter, then you are almost certainly putting too much fuel in the system, causing the misfire. Accelerate more gently.

tried the carb screw it seems to feel like the throttle is sticky but the cable is moving freely

What about the other stuff I mentioned?

Crap underneath the slider?

this bike is religiously cleaned everytime after use so no crap in there mate have recently changed the inlet manifold would that change anything?

You could have an air leak in the manifold seal. When the throttle is closed it sucks air in from there. Did you gasket/instant gasket it?

Crap underneath the slider?

Thats tricky, balance and aim are really difficult....

The replacement manifold is the first place to check, possibly a leaky gasket, disturbing the carbs can always bring problems.

:lol:

I mean the throttle slider. The actual plastic sleeve beneath the grip, that the throttle cables attach to. I've known a couple of bikes pick up a lot of fouling in there.
