thanx for reply,battery is new and fully charged
test the volts?do you mean test the battery under a load??

[bladerunner]

Do you have an after market alarm/immobiliser? If not it does hint that under the load of powering the starter motor not enough voltage to power the cdi. Put a meter on the battery to see what voltage it reads when it's spinning the starter motor and post it up here.

Read off the volts with nothing running and then read them off again with the engine running.
Also as above see how much they drop when cranking.
