keeps cutting out and engine blipping

hi, i have an sv650s 57 plate which keeps cutting out when at the lights or junctions and so on! also when I'm going along at low speeds it dips for a brief second on the revs then back up, any ideas or help would be great I'm wondering if it could need the carbs balancing???

It will not be the carbs as yours is a fuel injected bike, therefore has no carburettors.

When did it last have a service, by who and do you know what was done?

by carb balancing i was thinking throttle and valve synchronisation . it was last serviced about 10 month ago but not sure what was done as i didn't own her then

What mileage is the bike on now?. Throttle body balancing is due at the 7500m service and then again on the 14500m, so every other service.

Is yours a K6 or K7 model as the K7 has an idle speed control valve so the throttle body balancing can only be done if you have the SDS or OBD software. The idle on them is non adjustable.

Some bikes can be sensitive to throttle body balance, more than others. I had a GSXR750K3 which needed them doing every service.

just under 25000 now and its the k6 model, how could I be sure if it needs to be done or not?? or is it just best to hook it up and have a look? she rides fine when I'm giving it the beans

Check your idle speed adjustment as a low idle can cause those symptoms and is simple to adjust - remember though to ensure your bike is at full working temperature when making the adjustment.

Throttle bodies out of balance will generally show as rough or dipping idle, sometimes they sound like its "hunting" and slightly rough throttle response. Generally on full throttle they dont feel too bad but it does depend on how far out they are.

Thanks I will have a look at it and see what happens what should it be???

1300rpm + or - 100rpm.

Thanks will give it ago!!!

Throttle bodies mucky? Causing them to stick?
