Will a choke cable from a50cc 09 or a 10 gpr fit a derbi gpr125 04

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

Sounds like you seized the engine mate, I think its about £900-£1000 for a rebuild.

Hi and welcome to FixYa,

Initially, check for:

• color of burn tips of sparkplug; if very light brown to almost whitish, then lean. Check for an air leak;
• if black, sooty, then rich, check for a vacuum leak or oil/gas mix proportion.

SOURCE: what size is a derbi gpr 125 piston seal kit?

GPR125 '05 model engines have a piston of 56mm diameter

Ride safe
