OK, just like the later models. You are lucky. Many, many of the Yuasa batteries leak. We've found several new bikes at our dealer with the problem.
I was lucky too. My original Yuasa didn't leak but when it died, I opted for the Motobatt due to the leakages I had seen or heard about. Also, Yuasa advises not to lean them over whereas Motobatt says it's okay.
I'll keep an eye on it (you have to take the seats off to see it) but I have a suspicion that I'm probably easier on my bike than most people.
My original mirrors lasted over 20,000 miles; most broke in far less than that.
My original rear suspension went 23,000 miles; most were sacked out by 15,000.
My tappets went 40,000 miles before I replaced them; that's more than most.
My original plug caps weren't replaced until 40,000 miles; most were gone in less than that.
I get 6500 miles out of a rear PR4 and 13,000 miles out of a front; most people don't get that many.
So I guess I'm not too surprised that my battery is holding up better ... ?
