Hi folks. New on here. Originally posted this in workshop knowledge base, probably wrong place sorry.

Done the manual cct conversion last week following cybercarls instructions. Good clear instructions. Job done. Since puting it all back together I'm getting an intermittent fuel or electrical fault. When it kicks in it's usually when it's under heavier load or acceleration. Sometimes it's just a flat spot and sometimes it's like it's running on 1 cylinder, sometimes clears and other times revs die and conks out. Retraced all steps to double check. Only thing initially wrong was vaccum pipe on fuel tap was on the wrong housing into the tap itself and bike wouldn't even run properly on idle in garden. Changed that around and bike ran fine till 10 mins in on a run and this intermittent fault started. New plugs and a fuel treatment done also. Any ideas welcome.

Fuel tap fully open?

Hello and welcome to the forum, your fault is a tricky one, could be either fuel or electrical
going by the symptom, double check your work, check timings, carbs, plugs, coils
not much help really im afraid, revs freely at idle ?

Do tell us more on the fuel treatment

Chris.

Update bike fixed. Schoolboy error. Whilst looking for the original fault when it wasn't even idling in the garden, I stripped the fuel tap to check the diaphragm and spring as a last resort, as I had double checked everything. It was at this point I realised the vacuum pipe in the wrong outlet. When I assembled the fuel tap I did so wrongly, with the backplate turned 90 deg and the vacuum outlet pointing downwards instead of sideways. Fixed the problem and bike pulls like a train again, no flats pots, happy days
Chris, was redex. I usually use millers but it was a Sunday and the closest place was tesco so I made do this once. Next job is regulator/rectifier.

Glad you got it sorted, I had a vacuum problem a few weeks ago, you do the difficult stuff and the simple bits catch you out sometimes

Nice to hear it was a simple fix, I'm pleased you found it
I was wondering if it was something to do with the fuel treatment, I'm glad it wasn't.

Duffy's right, it is sometimes the simplest of things that can catch you out.

Thanks for letting us know,

Chris.
