Recently, (even after being warned by the Dealer ! ) I managed to leave my ten with the park lights on for a 13 hour stint. Parked her up in the Truck park at work in bright sunshine in the middle of the day not realizing I'd turned the ignition right round to park lights. On the return to base while refueling the Truck in the dark I noticed a glimmer of light coming from the corner of the yard where the bike was parked. Oh s*** I thought to myself. But to my amazement the big Ten fired up no problem after being left for so long. I can only put it down to the fact that the week before I'd changed the park light bulbs to LED bulbs.
I also invested in an Optimate battery charger/minder, as my local friendly dealer tells me that when bike battery's are operating at less than 80% the starter motors don't engage properly & can cause premature wear leading to a $800 bill. Which he see's a lot with smaller battery equipped bikes such as WR's.
I'm just happy not to have had a miserable walk home at 3.30am for some $12 worth of LED bulb's.
