Do you have a check engine light on? Are you saying that the engine idle speed is excessively high? If that is the case have you checked for intake manifold vacuum leaks?
Maybe this will help. This is a common problem that I have had with my GV250. Almost the same bike mechanically by Hyosung.
If the battery is low on charge and you are lucky enough for the bike to start. As per normal when first started it revs higher because the bike is cold, this turns the alternator fast to give you the electricity you need to keep the bikes computer working properly. Bike will warm up and revs drop down, alternater not turning as fast, not as much electricity being made. Bike will either stall or rev up and down irradically to try to produce its own electricity. This will occur when the battery charge is low and bike is at low revs, for example when you slow down for traffic or you stop.
If this is your problem. To resolve it when you are out on the road, keep the revs up, twisting your throttle gently when you are going slow or stopped. Give the bike a good long run on the open road to give the battery some charge from the alternator.
Make sure your battery is maintained. If you dont use your bike for a while it will lose charge just sitting there doing nothing. Give the battery a good deep cycle charge or take the bike for a good long open road ride.
I also have a GV250 EFI 2010 model. Make sure you do a full deep cycle recharge of your battery, check water levels etc prior to charging. A standard basic $40 to $70, 12 volt car battery charger shall suffice for your bike battery. Or take the bike for a good run for a few hours on the open road the get some charge in the battery. A very common problem for this kind of motorcycle whereby being a fuel injected model it requires a minimum amount of power to run the computer that controls fuel mix etc. When slowing down dropping down to second and into first to stop at traffic lights etc the bike will often stall if the battery is flat and the bike is at low revs. You can compensate by adjusting the throttle slightly to keep the revs up, causing the alternater to produce more power to keep the computer at a minimum voltage input. If the battery is very low on charge at low revs it will either stall or continuosly rev ridiculously high and low to try and produce anough power to run the ECU. This is a very common problem for this bike. Very prominant if running add on fog lights as well, like I do. Easy to fix, make sure battery is fully charged before you use. A lot of people buy a small trickle charge battery charger to put on their bike to keep battery maintianed when sitting in the garage. I only use my bike in good weather and usually only on weekends. Embarrased the hell out me first time my bike reved up and down, as it was in heavy peak hour traffic. I got some funny looks.
Attach a multimeter to battery and set at DC voltage. Measure voltage output at idle, then rev engine until light comes on and check again. That will tell you whether it's an overcharge or lack of charging causing the problem. Make sure you check belt condition and tension before, to eliminate that as a cause.
They have two separate screws? one for fast, one for slow.for the slow setting, first start the saw then screw until motor runs smooth without chain moving....if to slow the motor will stop....for fast screw....rev motor flat out then adjust so it screams its head off so to speak....it will need all its power for cutting wood so don't think you are opening it up to much as its designed for it.
