It just wouldn't start unless I put it in prime for a minute or so, then took 5 or 6 seconds to fire up. I felt sure that I had a carb problem. Before I stripped the carb I decided to charge the battery, as I thought I may have run it down a bit, trying to start. After charging to 13.32 volts, it dropped to 12.36 volts. I reckoned that this was a bit low, so I bit the bullet and went down to the local vehicle spares shop, and got the equivalent battery to the factory fitted one for €30.00 ($41.00). Charged it overnight, fitted it, and, voila, the bike started, immediately, at the touch of the button. Just goes to show that what seems to be a carb problem can be something else entirely.

I had a similar problem when I purchased my used gz250 last September. I eventually ordered a new 12v 7ah agm battery off ebay for $22.00 . all I had to do was install it and it cranked right up. It was sent fully charged.
