All that time on track before the race and then the throttle acted up towards the end of qualifying. I had converted the old CSL Elite throttle & clutch to Hall effect sensors last weekend and used them all week without problems, so was annoyed when the throttle would only give me 70%. I quickly realigned the magnet on the throttle and it lasted through lap 1 of the race, but then was giving me only 50%, so abandoned. Instructions I followed said the magnets wouldn't shift, so I've now applied duct tape and hopefully that will be my longer term solution.
