Were is the oil drain plug at on my shadow vt600 first time doing it myself

To change your oil you will need 4 quarts of oil, a filter, and a new aluminum drain plug washer. You can reuse the old drain plug washer if it has not been squished out of shape. Your drain plug is located on the left underside of the motor, part # 20 on the diagram. To change your oil you will need 4 quarts of oil, a filter, and a new aluminum drain plug washer. You can reuse the old drain plug washer if it has not been squished out of shape. Your motorcycle comes from Honda usually with 10w-40 mineral base motorcycle oil. You can use any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier. Your oil filter is located on the back side of the motor in front of the rear wheel. Part # 10. Pour in three quarts of oil to reach the high mark on the dip stick or inspection window. Make sure the motorcycle is upright or on the center stand when checking the level . You will probably need 3.2 to 3.4 quarts to hit the high mark. Run the motor for a minute or two to fill the oil filter compartment with oil. Now recheck the oil level and top up as needed. If you want to try an inexpensive full synthetic oil that is JASO MA rated 15w-40 Shell Rotella T Synthetic fits the bill at about $22 per gallon. All brands/manufacturers make a motorcycle oil. Some are very hard to find. Just make sure that the oil you pick has the JASO MA Japanese engine Rating to protect your motorcycle engine.

I have a honda cx500d 1981 and it has oil spray out of the exhaust where should i start to look to fix it it sprays a lil bit when idle but when you rev it oil really comes out

First check your oil level. If it is too high , your engine is full of gasoline. You will need to change your oil, drain the air box pollution tubes that hang down in front of the rear wheel (place a pan under the tube and pull out the plug , drain the tube , and replace the plug), check that the air filter is not saturated with oil (if so replace it). You may have a bad vacuum diaphragm on your petcock that is leaking gas into the motor. You can rebuild the the petcock with a K&L rebuild kit or replace it with a new one. You may have a sunk float or a worn or stuck float needle. Take the carburetors apart clean and inspect the components and replace as needed. Unfortunately, even a perfect motorcycle can have a float needle stick and fill the engine with gas forcing you to change your diluted oil. the only answer for this is to always turn off your fuel petcock when not riding.

I need to know to change my oil on my honda shadow aero. I would also like to know the best oil to use, how much oil and in general a brief description of the process, thanks! (this is so i dont have to...

You will need an oil filter (Fram,Honda, Emgo) an oil filter wrench (Honda or K&L) an aluminum oil drain plug washer, and any oil that has the JASO MA motorcycle oil rating. 10w-40 for cold climates and 20w-50 for warm climates and 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. Center stand the bike, use the wrench to unscrew the filter and place it in the pan. Wet the lip of the new filter with used oil and screw onto the engine. Be careful not to over tighten ( you will regret it next oil change). Place the pan under the drain plug and remove using a six point socket. Inspect the aluminum washer if it looks like a normal washer re use it. If it is deformed replace it.Put the drain plug back in with the sealing washer and snug it up tight. Do not over tighten , it only needs to seal the oil in not hold a cylinder head on. Grab a funnel and take out the fill hole plug , usually the dip stick on a Honda and pour in 3.5 quarts of oil. Put the plug back in , start, and run the motor to fill the oil filter. Now check the oil level and top up as needed you should not need more than 4 quarts total. If you want the bike to run cooler and shift easier you can use synthetic oil ( costs more ).
