At £59.99 for a complete new dizzy it was worth a chance and I wasn't disappointed. It was a simple swap over, just pull the old one, put in the new and that was that. Unfortunately the timing light was broken so it's just set approximately for now, but even so the difference is noticeable. I realise that some of the difference will be down to a new dizzy compared to a worn one, but I'm still impressed and no more points to worry about.
