1999 cbr 600 f4 streetfighter looses power when accelerating
So round March I crashed and ended up streetfighter. Not bad changed levers and got new headlight. Bike ran fine. Then I crashed again and this time bike rolled over completely. I fixed it and got it running but when I accelerated it would stutter and bog down(loosing power), and if I gas more it powers back up. I changed spark plugs and got my carbs cleaned and synced. Made my issues better but I cant clear it all up. Any suggestions?...

Ouch. Two crashes in a season is brutal. I guess if you're asking for suggestions, it'd be to take it easy on the old girl
I'd recommend starting with a good visual of any damage areas. Check for crushed wires or sensors. If I'm taking a shot in a dark, it could be a throttle-position sensor (can't recall if your bike came with one) or maybe a cracked airbox or other intake component. Pull plugs and check for lean/rich. Confirm fuel flow. Make sure your tank vent is clear. If the bike's been modified, you'll probably want to re-check your work just to rule it out
Does it idle okay? Will it stall if you stay on the throttle? Does it do the same if you rev it (no-load) or only when you're trying to roll-on?
