Certainly worth checking, however, mine has new contacts fittedTrada said:I've just read an old article somewhere that says an old fuel pump could also cause the problem. Might strip and clean the contacts on mine when I get started on it.

Trada said:Not used to running a twin so not quite sure. It's just doesn't quite feel smooth at low revs and speeds, I'm having to keep the revs over 3,000. It just feels as though it's surging a little if you try to hold the revs at a constant low. And I always expected a twin to be quite torquey but it's not, or is that just me being used to honda blackbird. Once running it does pull upto 110mph/177kph, so far that's as far as I've taken her.
Wigan Chris said:I also get the low speed surging on my '02 Vara. happens between 2k and 3k revs, on a roughly neutral or slightly positive throttle. happens when cold, when hot... very odd.
Trada said:Thanks Chris, I have been told by one guy it's quite normal on the older models so I'm not going to worry too much yet. I will look at the exhaust joints for blowing etc and the plug colour first and get a mechanicic to do the carbs when I get some time. The bike is new to me so I'll run it for a month or so before getting it set up and serviced by someone who knows how properly.
Just to bring this up again,Phil said:My carbadero has a slight surge at lower revs on light throttle, it's not a problem & I'm used to it now - pulling the choke halfway in cures it so I'm assuming they are too lean in that area. I will try fitting another .5mm washer under the needle sometime to see if that cures it.
They don't seem to like sub 3k in high gears.
Carbs balanced and everything else seems good/std btw.
