2000 YZ 250 rear shock setting

I just got a new rear shock and i need help on the settings.....  when i push doen on the seat it bounces up fast.......it seems loke there are 20 clicks on the top and bottom adj....rear seat is high so I am going to adjust the spring some.....how do i know if there is oil in my shock?  if there was no oil when i push down on the seat and let go it would bounce 4-5 times instead of coming up and staying put?  

Do you have the manual? It will tell you what clicks stock is which is where you should start. First thing is to set your sag.

I love this dirt stuff.

I looked at the manual...its doesnt say much about the sag....where is it supposed to be?  I adjusted it some and it feels less springy but i didnt want to go too much....I took it for a ride and it feels ok but wow does it wheelie easier than before...3rd gear NO PROBLEM..probably even 4th if i had more room  

LOL. Them 2-strokes will wheelie any time you wish no matter what gear your in.

Her is a explanation of sag by JZ.
Bike sag (weight of bike only) and race sag (with a rider) are the most important steps in making sure the bike will work optimally. Basically, bikes are made to work in a certain range with a certain weight on them. Adjusting the sag into this range will keep the bike and the rider happy. If you're too light or heavy for the stock spring, this will show up obviously when you're setting the sag. As always, grab your manual and read up on your bike's suggested settings.

It's always good to start back at the manufacturer's standard settings if you're having trouble or looking to improve your ride. They spend a lot of time testing for baseline settings, use them!

You said your book don't say much about sag. Do you have the operators manual or the repair manual?

Owners Service manual.....I am 185-195 lbs so I know I have to keep the spring stiff.  I think I might be alright, before I have the spring softer so I could touch the ground better but that was wrong.... I will test more and then adjust the rebound stiffer if the rear bounces up too fast.....I adjusted the compression setting way off to see if i could feel a difference but it felt the same....this setting is downward force right?  

You should still set your sag before anything else.

Measure the distance from rear axle to a set point on the rear fender with your bike on a stand.

Then put all your gear on, have someone hold the bike while you sit on it and have someone else measure the distance in the same spot you measured before.

The differance should be 4" or 100mm. This is a good all around starting point.

Ajust your rear spring to acheive this setting and set your clickers to stock.

Ride the bike and ajust your clickers accordingly, 1 to 2 clicks at a time.

http://www.tootechracing.com/suspension_tips.htm This is a very good how to set the sag article.  After setting the sag make sure your clickers for compression and rebound are back at stock and then start adjusting them to meet the current track conditions.

Read through these setup tips they will help you understand what you are adjusting for.
