Put 4 quarts in my 2003 roadstar and still does not touch dip stick

SOURCE: 2003 YZ 250 Oil Change

Use 10w40 in the gearbox. Get the oil from your Yamaha dealer along with any filter your bike may need. Some bikes use an oil change as the "filter". To drain oil, get the engine warmed up and turn it off. Put a pan under the gearbox and remove the oil drain plug. Replace the oil plug when the flow becomes a slow drip. Change oil in late spring, the middle of summer and in early fall. Remember to lube the chain and adjust it when needed. Lubricate the cables with liquid graphite. Lastly, install a stock spark plug. Now go for a ride.

SOURCE: oil level YZ 125

Hello....for the crank case you will want to use Yamalube 4 (10w-30) or an equivalent SAE 10W-30 SE motor oil. There is not a dip stick on the bike, Need to measure teh oil in accordance with Yamaha specs. You will need to check the owners manual or contact the local dealer service department and should be able to tell you how much needs to be added. If you don't have good 1qt mix cup you can get one at a good motorcycle shop. These are very help full in accurately measuring your premix oil for the fuel as well. Hope this helps

SOURCE: Oil change, no dip stick or niveu plug?

If you check here you will see that #18 is "gauge-level"
This should show you the oil level.
Remember: Put inside the 2/3 of the total amount of oil and run the engine for 5 minutes.Then kill it and add the rest of the oil to the proper level.

SOURCE: 2003 yamaha roadstar leak fuel sometimes after I

Yes Rick, try a couple of tricks I know.First,open the carburettor drain screw located at the base of the carburettor,this lets fuel flow out of the carburettor drain located next to/under it.(To acces this drain screw look between the engine cylinders from the LEFT of the bike)While the fuel is draining out,tap the fuel bowl.Next re-tighten the carby drain screw and see how that goes.I would suspect your bike has a vacumatic fuel tap that has 3 positions on it.1 marked on, 1 marked res, 1 marked pri.If the fuel leaks occur when in the on or res position this means part of your problem is a leaking diaphram in the fuel tap.Replace this & when engine isn't running,no fuel can flow to the carby when it's in the on or reserve positions.After ensuring the tap is ok, and trying the first trick,if it still leaks,well then you'll have to pull off the carby and give the needle and seat a clean.
Hope this healps Regards Andy Porrelli

SOURCE: I have a 05 roadstar I need to know how much oil?

Contact a Yamaha dealer. Using the incorrect amount, or wrong type of oil could lead to having the forks collapse while riding. It will vary also from model to model, so just because it works on another bike doesn't mean it will work on yours.
