SOURCE: acceleration hesitation
Depends how long since your last tune up and mileage. I would do a normal oil change, oil filter, air filter and plugs. If she still does it, try checking for a vacuum leak. Start the vehicle and spray "lightly" carb cleaner around your vacuum lines. If you have a leak the engine will increase in idle suddenly. Replace the line or part. AS A LAST resort and pretty rare is the distibutor. They usually run about 75.00 to 110.00...hope this helps.

It is on the same button as the Trip Odometer. Cycle through until you see Tire Reset and hold the button down.

Ok, there are many issues here that you will need to inspect. I recommend changing the fuel filter and pump as well. this will fix the hesitation. the intake and exhaust manifold gaskets will need to be replaced as well. this will stop the backfiring.
I also recommend checking and running a teat on the PCV valve and inspect the PCV hose as well. it could have a leak or a small crack on it.
Check the air filter and change if needed. this will help with acceleration issues as well. Next, i would run a check on all plugs and the complete wire set as well. change if needed.
Inspect the injectors for leaks and lose wires. make sure they are in good condition. replace any injectors that isn't firing properly.
Ok, there are some sensors that you will need to check as well. i will list them below.
SENSOR CHECK LIST--
1. Check the O2 sensors for worn wires.
2. Check the MAFS(Mas Air Flow Sensors) Check for Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit.
3. Check the Air Cleaner Temperature Sensor. this sensor could be damaged ro have loose wires. check accordingly.
4. Check the Throttle Position Sensor. this device could be connected wrong or it may be faulty as well. replace if needed.
Be sure and inspect all the above and repair any problem spot you ruin across during your inspection.
Please rate and god bless:)

Sounds as if your timing is not quite right. You need a manual, but The best I can offer is a 98: http://www.carlsalter.com/motorcycle-manuals.asp , it may help, but if you only have 1100 miles on it, I would be taking it to a qualified mechanic to be fixed. Up to you.

Hello and welcome to FixYa!
As a first course of action, i strongly suggest that you replace the transmission fluid. If the fluid is burnt the transmission may fail, one good reason why you have this issues. If it still fails after the fluid replacement, go for torque converter replacement. The torque converter controls the shifting of the vehicle and when it's faulty it tends not to shift or just holds on a certain speed.
Hope this helps and thank you for using FixYa! Have a good one!
