Gear Oil Change
by: Peewee

Well, I should have come here before almost having the cover off. Sure enough, 10mm drain and fill bolts. Bada, bing, bada, boom. Thanks a million. I was ready to toss that baby in the trash heap of history.

Says drain and refill with 190-ml but always overflows before that
by: Anonymous

Im in the same boat, the manual on my Kymco Xciting 250 says to drain it and fill with 190ml but I never even come close until it starts overfilling. Its always concerned me, and Ive never gotten a straight answer on it from a tech or mechanic, but I also assumed if it was overflowing, then it was full. I am concerned about using too much, or why after I drain it I cant put in the same amount the manual says I should replace it with. All very strange and never well explained, so if someone has an official answer, Id love to hear it.

You Made Me Look

I had to check mine for this. In the back of the engine at the rear wheel are two 10mm head bolts. One is at the bottom to drain the case, the other is at about the three o'clock position towards the rear. They're the only 10mm bolts back there. You open both to drain, bottom first, obviously and then you put the bottom back, squirt in 85W-90 gear oil until it overflows in the top bolt hole and wait until it stops running and put the bolt back. If you're waiting for me to say "install 180cc of oil" forget it, I'm from the squirt and dribble school. I know it's full as long as it's on the centerstand and full to the bolt hole.

I hope that's an adequate explanation.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...
