have u done the basic checks .

have u checked the wireing for the ignition amplifer and coil . use a volt meter to check the coil voltage which should be 0.8 me thinks not 100% sure as cannot put me hand on the manuel as it is at home .

also double check crank sensor and phase sensor are fitted correctly
and gap should be 1ml from the crank

workshop manuel is a good investment which helped us a lot

will have a look at ours and post later
