laser1 Posted June 8, 2009 Report Share Posted June 8, 2009 (edited) NGK BP5ES, BP5EV work well. An 8 would be very cold for this bike. Gap to 0.6mm Note - I am refering to a GasGas 300 pro - not a Fantic. I was thinking somthing was weird since you listed a GG250 and wouldnt know the plug...Now i know I probably had the wrong bike.
