How do i do compression test on 2006 yzf 450 f


Remove spark plugs. Insert compression tester pressure pipe against each plug hole in turn. Spin the engine for 15 seconds whilst holding the pressure tester in each plug hole. No throttle. The readings should be the same from each cylinder or at least within 1 or 2%.

I have a Compaq NW9440 Mobile Workstation - it keeps shutting down every 15 minutes or so. At times, it will not restart right away. I thought it may have been the CMOS Battery, so I replaced it. It's...


The most common problem you get with a laptop is overheating, this can cause for it to shut down while operating to prevent more damage.

You will know if your laptop is overheating if it happens one ore more of the following:
-The keyboard and the bottom of your laptop are very hot when the laptop is working.
-The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
-The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
-The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner.

If it is not overheating, then it is a hardware failure. Could be the RAM memory, or the motherboard. You can only corner the problem by testing with different RAM modules or motherboard.

I have a ford 1994 Escort, it keeps cutting out whilst driving. Cleaned the idle speed valve and throttle body, didn't work. Changed idle speed valve, didnt work. Cleaned the the lamda sensor, didnt work....


There is many thing that could go wrong. I will list some for you to try to pinpoint the problem with out paying the mechanic to do.
1. Cloged fuel filter and possible inpurities in fuel system
2. Faulty or incorecctly gaped spark plugs
3 Fault in the fuel or electrical system
4. incorect ignition timming
5. Defective spark plug wires
6. Low or uneven cylinder compression pressures. Perfom a compression test.
7. Weak or faulty ignition system.
8. Vacuum leaks in the intake manifold or vacuum hoses.

Whilst riding at long periods at high speed my bike just shut down and didnt seem to have compression once i went to kick start it again.yz 125


It sounds like you cooked her. If you are jetted lean, and run it wide open for a long period of time, it melts the ring to the piston.
Do a compression test, remove spark plug, thread in gauge, and hold throttle wide open and kick untill the guage stops climbing (Around ten or so) Less than 100 psi is bad.
