Help! I have a dead zone when I accelerate, where the bike will stall out if I don't go over it quickly. I have 1300 miles on it, but it was laid up for a year because I was busy with my dad (aka my mechanic) who recently passed away.
Idle is fine. Cleaned and re-oiled the air filter, replaced plugs, all the normal maintenance. Tried cleaning (what I believe is) the main jet under the bowl with carb cleaner and removed alot of green gunk, checked that there are no intake leaks at the connections. I'm a fem whose been riding since I was 5 or 6 (thank you, dad), but new to trying to fix it myself. Idles fine, also drained the gas tank and checked the lines since I didn't ride last year.
I'm a bit skiddish getting into the carb, but wonder if there are more jets I am missing. Any ideas, anyone?

It's most likely something to do with your carbs.
Carbs have circuits in them - different paths for the fuel to flow through. When you open the throttle a certain amount, the carbs let fuel flow through a certain circuit. if one of these circuits is blocked, it will result in a flat spot when you have the throttle in that position.
When you let the bike sit for a long period of time (6 mos or more) the poor quality of today's gasolines causes them to vaporize, leaving behind a varnish-like crud in your carburettors. You must have your carbs taken apart and cleaned. You could do it yourself, but it's alot easier to take it to a mechanic who uses industrial parts cleaners and solvents. Using carb cleaning flud that they sell at the auto parts store is typically unsatisfactory. (They might as well put water in a can)

Thank you
This site was recommended to me, and with how quickly you responded, I'd say it was a good call. I did suspect the carb, and I wanted to give it a good shot before I got a pro involved. Sounds like I'd better take your advice. Thank you.
