Aup lads,
Just bought a 2001 GasGas EC 300 and it has a huge midrange flat spot. At first it struggled to get through to the end of the gears and stuttered etc. But after putting the needle clip on the leanest position there was slight improvement. It currently has a BR8EG spark plug in. I was told by the local bike shop that in their manual it says to use the iridium BR10EIX. Could this help the flat spot or is a BR8EG fine to use?
Thanks lads
