Sv650 idiling problem

[rinckley]

Just got to work this morning and the bike has been idiling at about 3000 rpm where it normally keeps at about 1500. It feels as if the throttle is stuck open just a little.

Any ideas?
Thanks

Does the choke leaver feel like it is floppy? i.e. the choke isn't going off totally? (as above comment re throttle cable, it could the a sticky choke cable).

The choke lever feels a little more loose than normal i think.

I had a look at the freeplay in the throttle cable and sorted that but it still happens. I cant see to lube it at the moment.

I realised i was rubbish at describing what was happening to it so i took a quick video of what was going on.

The revs go up after about 30 seconds of the engine running, they only drop again once its in gear and i let the clutch out a little. As soon as i pull it back in the go straight back to 3000ish.

Well I had a problem at the end of November so I took it to the garage and apparently the cleaned and balanced the carbs then.

Thanks, i'll take a look at it in the morning. I'm pretty terrible with the mechanical side of things, only been riding since october.

The bike can pretty much move off if i let the clutch out in first without stalling. Could it still be too much air in or would this definitely be the throttle cable?

On the video the revs are only going up and down because i put it in gear and was letting the clutch in and out.

I had a look today and couldnt see anything out of place. I adjusted the idle speed screw and lubed the throttle cable too (was only with wd40 though until i buy some cable lube). I thought it had sorted it but i went out on the bike a few hours later and the revs crept up a little to about 2000. The throttle does feel a little bit sticky though.

I had the same problem when my carbs were unbalanced, but it's a bit unusual for them to suddenly go like that. Know anyone that would have some vacuum gauges or a 'sync tool'? You can make your own with bottles and hoses haha

They apparently got done in november but i dont trust the garages work 100% as it took them 3 attempts to fix the problem that time.

I dont know anyone else that rides bikes, probably just take it to a garage if it keeps on.
