It could be the sensor needs to be changed... In some cases it occurs cuz of the voltage drop of battery output... how old is your bike cuz if its a few yrs old it might be the battery

SOURCE: can I extend cylinder for
You can get a 150cc bore kit from derbi which is very easy to fit and cheap. It's on derbi.com and will give you a performance increase of about 5 HP bringing your total to about 20hp. Once you do that you can get a bigger exhaust also from derbi which should add another 3hp. I have the derbi gpr125 4t and I have done all the above, top speed is about 90mph and accelerates very very fast. Good luck.
