Sorry I'm moving my post to this section as it is a bit more active.
Hi, I recently purchased a GasGas EC300 2006 from 'greenlane motorcycles', a dealer with whom I suggest you avoid like the plague due to many lies in the sales process and general bad customer relations.
The bike
Since purchase I have
Changed oil
New oiled air filter
Rejetted for best performance (40pilot, 180main), running 32:1 fuelil
The bike ran great, in which I decided to ride on the local motocross circuit, half way through the second lap, suddenly the bike refused to rev high;

This problem is now constant, I have checked the following;
Spark plug, replaced - BR8ES
Ignition coil, HT lead and plug cap replaced
Stator coil replaced - Electrex
Carb has been cleaned
Reeds are in good condition
Power valve is operating correctly
Piston appears clean and ring are in tact
Engine has very good compression on the kick start
All earth points have been checked
All wiring has been checked and re-shielded
The bike starts first or second kick every time, idles very strongly, but will not rev past approximately 5000-6000rpm. The bike can be ridden and still pulls at full throttle below this rev range.
At this point all I can think is that I have a faulty CDI? I have tried running the bike with both 'maps', bypassing the switch etc, but to no avail. Is there any way to test the CDI or anyone I can send it to for testing? Or are there any other possibilities you think I should consider?
