May 19, 2013 - the brake failure warning is flashing. Pull in the clutch and firmly press the start button until the engine starts. Did the light go off?

Since you didn't say if you have a dip stick or sight guage, or type of bike, I can only say refer to the owners manual. Some bikes need to be checked while the motor is warm and others cold. There are many different bikes that take many different amounts of oil. So the best bet is to fill to a middle level, crank it, and recheck.

Any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Do not use any oil that says Energy Conserving on the label . It will shorten the life of your wet clutch and transmission gears. Synthetic oils will help your bike run cooler and shift easier. I have not heard of a dipstick being available for your cycle. Always be sure to hold the bike level when checking the oil so you get an accurate reading of the level.

Here is the most accurate way to check the oil on your R-RT.

Ride bike till it is fully warmed up - 10 minutes
Park bike on side stand for 10 minutes or longer.... overnight.
Put bike on center stand and look at oil level window on lower left side of engine. Oil level should be inside the red circle. Do not overfill!!

The absolute best time to check the oil is when the engine is cold and all oil has drained out of oil cooler and lines into the engine sump. Usually before riding... Once properly broken in, your engine will consume very little oil.

The sight glass should show oil whenever the bike is stationary and level, either hot or cold. The warm oil concept generally applies for the easy pouring or viscosity of the oil. Warm oil flows better and is easier to drain from sumps, hoses, radiator's etc. Warm oil will drain better from all areas of the engine to give a better indication of the total oil in the system. The sight glass is generally hi-lo levels from top to bottom. Cheers.

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.

Dont stress. A LITLLE more than the level is nothing to worry about. Keep the oil level between the 2 marks when the engine is cold and you'll be fine. Best way is bottom level is for cold. Oil must be above this level when cold. Top level is for warm. Oil must be below this level when hot.

hi,
you can check the oil level in your bike by using the "oil sight glass" at the lower part of engine in the left hand side of your bike, just below the left foot peg.there are two marks, the upper mark referring the maximum capacity for oil level and the lower mark showing the minimum level.The oil level can be anywhere between these two marks.Please make sure of two things while you check the oil level in your bike.

• Run your engine for two min so that the oil is warm while you check the level.Never check the oil level in a cold engine.
• Hold the bike in upright vertical position while checking the oil level.
  

I have provided an example picture showing the location of the oil filter in a Yamaha v-star.Hope your problem is solved.Please rate my solution as helpful.Have a great day.

either way is fine on HD do not fill to the top of the dipstick if the oil is cold as oil expands when it is hot

Check the level with the bike cold and upright, not running.
