Throttle pick-up jerky

Ah, good point, well made!

I'm getting new cables for the comfort conversion, I'll lube the linkage then and see how that goes. Thanks garynortheast.

It sounds like the cables need oiled throttle and chokes!
Then balance the carbs

If it's still jerky, check and setup the clutch again

Hi Andrew, As I said further up, the carbs are nicely balanced, I am getting new (longer) cables, and it manifests itself when I feed power back in in gear, clutch out. As it has only 9500 miles on it, I doubt that it is dry, ratchety cables.

Some riders may not notice or care about this, especially the bods who slam the throttle closed and open to do wheelies, but I don't like it.

Id do the curvy usual suspects-----Choke plungers,throttle cable free play adjust,carb balance and pull the plugs to look at them.Maybe change them anyway.
Has your bike been standing---poss nasty fuel deposits?

Hi Biggles, I have done 1100 miles in a month with it and it starts and runs really well at all throttle openings, new iridium plugs.

I can only think this is actually to do with the controls and carbs because I can feel the suction of the inlets trying to hold the butterflies or slides (whatever they are) closed but as I try to open the throttle it seems to ping the power back on with a bit of a bang (relatively). I would like to have finer control over the throttle at that time especially when I'm cranked over.

Have you checked that the throttle cables have the correct free play in them?There is an adjuster the cables at the twistgrip end.Long time since I did it but instructions are in the handbook.

its a V-Twin they all do that.... it takes a while to get used to it but a tip till you do.. for going round mini roundabouts and such is to keep the revs up while slipping the clutch and 'drag' the back brake slightly which smooths it out, just like doing a turn in the road.

Seconding Biblio - a slightly snatchy/jerky throttle, especially in low gears, when say coming off the revs and then applying them back a few moments later, say after a change down, has always been a feature of any one of my three SV's. It's what I understand a twin tends to do.

Best advise is that when making minor throttle changes in a low gear, rather than "twisting" the throttle with the hand, just literally "squeeze" your fingers tighter round the throttle, which will just move it a smidgeon, and less than an actual twist movement.

OK guys, enough people have said that it is the bike which aligns with my thoughts so I'll just have to get used to it and refine my throttle action.

Thanks guys.
