Here's a reminder for you to check your motorcycle battery's electrolyte levels. Last year, I purchased a brand-new Kawasaki KLR650. I've had no problems with the battery, but I did notice that the owner's manual calls for a battery electrolyte level inspect every six months or 3,750 miles, whichever comes first.

I've had that bike for a year and a quarter and didn't think to check the levels. Who uses a non-maintenance-free battery any more? Anyway, remember to check your levels every once in a while and throw some distilled water in there if the electrolyte levels are low. All six cells in my KLR battery were at the low mark. Now, there're high.
