My 450 holds about 1.2 qts or litres, the 426 will be similar, 1 litre without the filter change
but you when you drain it there is another drain on the frame down tube. and to test the level you need to start and idle the bike for a minute , for the oil to pump through and establish a level that you can read on the dip stick .

I was given a 2000 yamaha DT 125 and i was told needs regular fuel and 2t oil but i dont know the combination or how much mix to the gasoline please help


Are you sure this is a DT 125 as with this particular bike it is self mixing there should be a separate tank by the handle bars just under the front plastics opposite the water tank this is where you fill it with oil then just put gas in the gas tank and it will mix it self you do not have to do anything else do not put oil in the gas tank with the gas mixing would usally be dirt bikes or really old bikes only

What is the oil fill hole in front of my gas tank on my 1991 Suzuki dr350 for


Your bike has motor oil stored in the frame instead of a " tank". there is a frame drain located at the lower portion of the front downtube of the frame and the engine. If you are changing the oil you should drain both the engine and the frame and then re-fill. since you bike has two pumps, one to feed the motor and one to push the oil back to the frame, you need to add some oil and then run the bike for 30 seconds or so. After you have run the bike for 30 seconds check the oil in the frame and add as needed.

thanks and I hope that this helps.

How much oil do i put in my 02 426


Hi, here you go:

Oil capacity is the same as the 250.
1.5 ltrs at oil & filter/s change.
700mls to 1ltr without filter change.
This bike has what is called a dry sump. You fill your oil at the filler point that is located in front of the fuel tank on the frame. It uses the front frame tube as a container for the oil & pumps it back & forth to the motor. This bike has two oil filters.A cartridge type one located behind the small round cover held in place with two bolts that is located on the clutch cover.The other filter is a screen attatched to the spiggot which the hose from the frame(front bottom) slides over. Remove the hose(frame front bottom), undo the spiggot that the hose was attatched to,and as you pull it down to remove it you will see the fine wire screen that is attatched to it.
When you remove the oil filler plug(in front of the fuel tank)you'll notice it has a dipstick on it. When you fill the tank the oil level will seem high. Run the bike first(to let the oil circulate) then check the level on the dipstick. It will now be much lower. adjust the level to the correct level & away you go!
I recomend changing the the cartridge oil filter & cleaning the screen every time you change the oil. Use a high quality oil like Motul & change the oil regularly.
Also keep your air filter clean & oiled properly.


Good luck!!

How do u fill the down tubes on a hoda shadow


First of all do not add oil to your front forks with out draining them first. If you over fill your forks with oil you will damage your forks. To change your oil in your forks, first center stand the bike and lift the front wheel by putting a jack under the motor. Remove the front wheel and axle and put a pie tin under the fork tube. Reach up into the bottom of the fork tube with a hex key and loosen the screw but do not remove. Now take the air pressure cross over tube off, this will allow you to unscrew the fork tops( On some bikes you may have to put a towel on the tank and unbolt the handle bars to get them out of the way.). Pull the screws out of the bottom of the forks and gently pull down the oil should come out now. If you need new fork seals take the lower tubes off and replace(You may need to take off the fender and hang the calipers with wires.). Turn the lowers over and dump out the oil and reinstall fork lowers. Snug up screws and sealing washers on the bottom of forks you can not tighten till you put on fork tops. Now pour in measured amount of oil, again do not over fill. Put on fork tops and air crossover tube. Now tighten screws on bottom of fork. Finish reassembling bike.

Gas leaking out where you fill the front tank


You probably have a defective fuel-tank selector valve. Its located on the left frame rail, halfway down. While the vehicle is running, tank"A" is pumping fuel to the engine, while tank "B" is getting the unneeded fuel that is returning from the engine. Thats why it is overflowing.

Changing fluids


Trans plug is under the Primary cover ( Left side ) and the Oil line is under the frame on the left side. Look for a oil line with a plug attatched to it. Run the bike up to operating temp. Primary and trans are the same thing ( Sport Trans fluid ) 1Qt in the primary ( fill throught the little cover on the side of the primary, and fill the oil through the oil tank. Put a little oil in the filter too, before installing, this will give the motor a little bit of oil until the rest of it makes it way through. You'll also need 1 p/n 11105 for the drain plug on the primary.

Where do i put the oil back in the bike after i drain the oil? drained the oil and now do not know where to replace this oil please help!


There is a dipstick near the top level of the radiator on the right side of the bike. Just remove the dipstick and pour in the fresh oil.
To check oil level, let the bike idle for three minutes then turn it off. Now use the dipstick to read the oil level.

Please rate this solution. Thanks Eagle!

Unsure about gas setup


Hi and welcome to FixYa,

It would appear that there are 2 questions/users on this post. Still, on your bike, normally, the tank hold plain gas, not premixed. The 2-stroke oil (2T) has its own reservoir attached to the right side, on the frame. The filler would be exposed and relatively easy to access and fill up.

On the Gearbox oil for 2-stroke engines with a wet clutch, SAE 10W40 is the standard.

Good luck and Thank you for using FixYa.
