Check the clamps and replace the screws if you can. Mine were bad when me and Berlin disturbed them

Re: Poor running on front cylinder - Curvy.
 

Well finally got round to getting hold of another set of carbs and that seems to have sorted it. Only part fitted them but the bike started almost immediately and sounds much better. Will fit them properly tomorrow and go out for a run to see how it is once warmed up. Quite chuffed as it's not seemed right since I first got it. Might even celebrate with a new can.
