I had a bike that had a reg/rec fault and since then use Optimate all the time to keep the battery in top condition no matter what bike I have. I've noticed with my Scrambler - don't know if it's with all Scramblers or peculiar to Ducatis, that it seems sluggish on starting, even with the Optimate connected. Ie it will turn over a couple of times before firing. Hasn't let me down, but my other bikes fired up immediately?
