I've recently finished painting my tank and a few other parts on the bike, I assembled it all last wknd but today I started the bike up and it started fine, ticks over nicely but when I try and open up the throttle it seems to die, it doesn't cut out it just doesn't seem to be igniting, it sounds like it's choking or something but then when I back off the throttle it revs fine, I can't get it to rev up without this happening, I hadn't started it for a while while I did the painting but before that it was perfect, could the battery not be the right voltage? Or maybe the breather not working? The only other thing I thought was a carb blockage.
Any help would be great
