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.

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
