How do i check the oil because i just bought a 2009 suzuki bulevard but there dip stick? and the dealer ship didnt give me an owners manuel

On newer model bikes there is no dipstick, just a cap.
so to check the oil level, you need to look on the engine cover itself.
there will be a sight glass, with 2 hash marks on the case .
lower line is minimum, top line is maximun

If the sight glass is too dirty, warm up the bike and then change the oil and filter.
Then watch the sight glass as you fill the oil.

if bike is equipped with a center stand, always check oil on center stand.
if no center stand then check oil with bike on kickstand.

The sight glass will be either on the right side lower engine cover
or left side lower engine cover.
it it round and about the size of a quater.

Hope to be helpful.
best regards
Big al

How much oil do i put in my 2004 yamaha yz250 2 stroke?

35 to 1 for fuel oil mix. if u r talking about crank case, i think 2 quarts, if there is a sight glass on side of cover, it should be right in center when bike is upright. If no sight and no leaks, just measure what you take out an add the exact same.

I need to know how to do a correct oil level check?

On the right side of you motor, there will be a sight glass.
You will have to crouch very low, and possibly lay on the ground to see it.
The sight glass is in the right side cover towards the back and at the bottom.

If your oil is in need of changing and has turned dark in color(black). The sight glass isn't so visible when the oil is black.

Thats how you check the oil level with the bike off the kicksatnd and you holding it staight up, while looking at the sight glass.

I have a 91 do i check the oil level on it?

if there is not a sight glass on the side, or a dipstick on the oil fill cap, then you check the level by draining and refilling it to the proper CC ammount.

Oil change

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.

I dont know how much oil to put in when i change it?

It's between three & four quarts. After you change the oil & filter, put two quarts of oil in it, then look in the sight glass while the bike is standing straight up. Add oil 1/2 quart at a time until you see oil in that sight glass. Fill until the sight glass has oil at least over the center, but not all the way to the top.
