The battery power of my Dr-z is getting weak.
It's time to change the battery.
It should be a level one technics of DIY.
Detach the seat with 2 #8 bolts, and take down the side covers.
The type of battery numebr is YT7B-BS, it's easy to get in Taiwan.
And, it comes with a reasonable price.
Just remember the + & - lines arrangement before you screw out the bolts.
First take down the - line, then the + one.
The old battery was dated August, 2010.
It's been 4 and a half years duration.
YUASA's quality was good enough for the master.
Put the cover of battery back on with a #10 bolt & grease the points.
Start the engine again,......
Everything is coming back~
Excellent~~
