Hi, I have a cf moto 500 and am having trouble with it that no one can help me with . It is derating while in 2and4 wheel drive but switching back to full revs when the difflock is engaged, which is the opposite to what should be happening, we canot find the problem a have replaced the 2/4 wd switch. The overide switch seems to be working ok all the relays and servo motors are working so all the components work and we fitted a new cdi unit and it is still the same. Any idea´s would be appreciated. Scottyb
