sv 650 starting problem help needed

[aermacchi]

I cant get my sv (00 Reg) to start, the last couple of times I used it it was misfiring and spitting back until itwas warmed up. It's just had a new battery and plugs fitted,so they should'nt be causing a problem. Anyone got any ideas what I should be checking for?

Is it turning over with authority?

Is it firing?

Air leak on inlet side?Have the airbox or carbs been disturbed and are they all seated back properly?

[aermacchi]

It's turning over ok, not firing too well, I'm charging the battery overnight to have another go tomorrow

Air leak somewhere, or in need of a balancing.
