Wat kind of coolant is good for a 04 yz 450? Engine Ice Collant. acn u also use regular car coolant? How many Qaurts of 4 stroke oil do you put in a yz 450? wat typ is good to use. (example 10-30) where do you drain the old oil from the bike? Hope to hear a reply from you

Hi, If it is a 2 stroke engine you will not need to check oil level. Because the oil is in the mix already. If it is a 4 stroke there will be a black or gray screw type plug on the crankcase. It will also have a dip stick on it. Good luck.

32:1 is a safe ratio for the YZ, with good non oxygenated 91 pump gas. I run my YZ at 40:1, but with 110 race gas and synthetic oil. The Yamaha Y2R 2-stroke oil is a great choice, never burnt down a motor yet. Have fun!

Head Gasket Problem, or cracked head , the heat, then no heat is almost a dead giveaway. Good Luck

no it should be fine as long as you put collant in it and it is not leaking collant anywhere make sure collant topped off

20w40 four stroke engine oil,
car oils will cause clutch slip
the semi synthetic and full synthetic are better oils but cost more.
Change the oil often, it only holds a bit over a litre

Headgasket leak?If you have not done so already try filling up the rad(when cold) and run the engine with the rad cap off and look for air bubbles, or you could go to a radiator service centre to check for carbon monoxide in the rad.

Please get back to me if you require further asssistance.

You have a 2 stroke dirt bike, off road only, without oil injection. Get a gallon of 2 stroke oil, get the mix from the owners manual or the dealer, should be about 1 pint per tank? Or 4 oz per gallon. It might be more. Don't try to get away with burning motor oil in there, it won't work, it will overheat the engine and could do some damage. Hope this helps.

Oil filler cap is on the left crankcase cover (engine side cover). This oils both the engine and transmission. Check the oil level on the dipstick located on the upper frame in front of the fuel tank. This should be done after the engine has been run briefly (idle for 1 minute), then kill engine and check.

Part # 6 in the diagram.

32 to 1 equals 4 ounces two stroke engine oil per one gallon of gas. Be sure to use two stroke engine oil and not motor oil.10w40 motor oil is for the gearbox.

i know you have to change the oil and oil filter but how often and is that the only thing different from maintance on a 2-stroke?. Im getting an 04 kx 250f any help would be great!The two most important aspects of four-stroke maintenance are frequent oil/filter changes and regular valve clearance checks/adjustments. And some four-strokes (RMZ450 for example) have a manual timing chain tensioner that must be regularly checked/adjusted. Everything else is exactly like a two-stroke.,,,
