Yes you can. i have done it a few times now.
Your starter could be weak and need a rebuild.
4 to 4.5 quarts ( measure what u took out and put that back in)
Where is the fuse box on a 2004 Yamaha Roadstar
With tools and a Yamaha repair manual.....
fusebox is under the left side cover on an 02 roadstar
4
The 1700 Roadstar puts out about 65 horsepower and about 99 ft. lbs. of torque.
Take off the seat (by turning your key in the ignition way to the left), and the battery is right there. You then disconnect the 2 cables (positive and negative), remove the rubber strap holding it in there, and then you simply pull the battery out.
4 spark plugs
The oil filter is under the battery.
I've got an 07 RoadStar, so it may be different, but my fusebox is under the left side cover.
There should be a small label on it. It should be on the neck.
