Where do you check engine oil? Should there be a

The Road Star takes 4.3 qts which is 4.07 liters.

In my experience, MOST Yamaha engines have the oil capacity stamped either near the oil filler cap, or if it has one, near the fisheye inspection glass.

The best advice I have seen to date states the following: Having replaced and tightened the drain plug, remove the dipstick and puur in half the oil. Note that this bike has an oil tank, so having added 2 litres or so, put the dipstick back in and tighten it. Start the bike and allow it to run for around 15 seconds to allow the oil to pump from the oil tank to the engine crankcase. Shut the bike off and add the remaining oil before replacing the dipstick again and checking for leaks.

Hope this helps. Please rate this solution

Hi,
Off course! The engine oil is different from tranny lubrication! Fill the engine oil via engine oil cap. If u have an automatic transmission, check the level of ATF by looking at the transmission dipstick. and fill it up via dipstick tube. If you have a manual tranny, check the gear oil via inlet nut under the transmission.
Hope that clears everything!

• There is a 8mm or 10mm plug on the back of the transmission (underneath the car) When you pull that plug if fluid comes out then it it full. If not you add fluid until it just barely comes out that hole and then the transmission is full.
• Now you add fluid from the top of the transmission. You have to look way down in the engine bay on top of the transmission for a red or black cap. It may say "do not open" or "open by a technician only." Take and pull that cap off and this is the fill spout for the transmission. It's a fill only, not a check. Add from this spout until it comes out that little plug on the back of the transmission.
• You will hear people call this a "sealed" transmission of "non-serviceable." Now you can tell them rubbish lol.
• To check the condition you can look to see if it is getting black or smells burnt. After 50,000 miles the fluid needs flushed and after 100,000 miles you need to change the filter and gasket for the transmission.

OIL LEVEL CHECK Every time you stop for fuel, check the engine oil as follows:

1. Park the vehicle on level ground.
2. When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
3. Open the hood and inspect the level of the engine oil tank. The fluid level on the tank should read between FULL or F and LOW or L.
4. If the level is below the LOW or L line, remove the cap and add enough engine oil to reach the FULL or F line. Fig. 1: Fill the engine oil tank located under the hood first
   
5. Install the oil cap and hand tighten.
6. After filling the oil tank, remove the engine access hole cover on the drivers side. Fig. 2: Make sure the oil tank is to the F mark Fig. 3: The oil dipstick is located under the driver's side engine access hole cover Fig. 4: Place your finger through the hole and pull straight up to remove
   
7. Remove the engine oil dipstick and wipe it clean.
8. Reinsert the dipstick, push it in as far as it will go, the pull it out and look at the level on the end.
9. If necessary, insert more oil through the oil filler cap next to the dipstick, this will completely top off the system. Fig. 5: The oil dipstick has two markings for level check Fig. 6: To fill the crankcase, remove the engine oil filler cap

The Yamaha Roadstar has a dry sump oil system. What this means is that the oil is stored in an oil tank to reduce the size of the engine. By storing the oil in the tank (which is under the seat and has the filler cap/dipstick, the engine does not need a sump under the crankshaft to store the oil. In this type of system the oil is pumped back to the tank after making its rounds through the engine. When you shut the bike off the oil will settle in the engine until you run the engine. The procedure to check the oil is to warm up the engine and allow it to idle for approximately 3 minutes. Do not rev up the motor during this time as it will cause the oil level to not read correctly. After shutting off the motor, check the oil level and adjust it to keep it in the proper level on the dipstick.

There is no dipstick on a Royal Star. To check the oil level, look for a glass window on the right side of the crankcase marked for high (max) and low (min) levels. Get on hands and knees and look under the front crankcase cover directly beside the right operator's footrest; you'll probably need a flashlight to read it.
