Yes, it is too low. The minimum normal compression is 125psi. The range is from 125psi to 150psi.

1999 Kawasaki VN 1500 Vulcan Classic compression very high

Take a look at the exhaust valves. If the exhaust valves are not opening, the pressure will build (sort of like an air compressor). There should be a cam for the intake and the exhaust, make sure the cam and the valves are operating correctly. Also, check your base gasket and head gaskets. If either gasket is too small, it'll boost your cylinder pressure. It is common to switch out the base gasket and/or head gaskets with thinner ones as an inexpensive mod to boost cylinder pressure. Lastly, too much carbon on the piston head or cylinder head can boost cylinder pressures (rare); the carbon can be a problem which can lead to detonation as well.

I have a 1999 ford escort 2.0 DOHC and it will crank but wont had a new fuel pump put in it and ive put a cam position sensor on it and a battery..its gettin fire and its blue spark but still no...

Compression is too low, it sounds like there is a head gasket failure. The compression should be above 100 psi as a minimum. Normally should be in the 120-170psi range.

I have a 99 sienna and the cylinders have low pressure what can i do?

If cylinder compression is too low, the car may not even start because of it. Have a shop do a compression test or a leak-down test to check the internal health of your engine. A good engine should have pressures of 150-200 psi in all cylinders and be close to each other. A worn or high mileage engine may have pressure as low as, say 125 psi, but if still balanced (close readings), would still run decent. Compression below that, especially below 100 psi, is serious trouble. ignition spark refuses to ignite the air/fuel mixture and you get a misfire-a non-working cylinder. Low compression can be caused by worn piiston rings or poor valve sealing. Low compression in 1 or 2 cylinders can be a valve problem, burned valves or valves not seating properly.
A leak-down test will check each cylinder and if there is a problem, the test will find the cause of the problem.

98 honda accord v6 only has 90 psi compression

90 psi compression is the minumun for gas engine to ignite, you have low compression what is the compression next to it? The compression on Honda V6 is 200psi. you can have a valve problem a blown head gasket, Also make sure your compression gauge is accurate by using another compression gauge

I want to ask wath pressure i put into the tayre of kawasaki kle500 front 90/90 vr21 rear 130/80 vr17

Hi there,

THere's a KPA or PSI reading embossed on the tire.. you should follow that. Or as a general rule 31 PSI front 30 PSI back for a stiff ride. 28 psi rear 29 psi front will give you most cushion at tacky road-to-tire friction.

Hope this helps

What should the compression be for a 1983 GS650GT, I have readings of 160 psi on three cylinders and 180 psi the other, I'm going to redo the check again with a different compression tester.

Taking compression test:- the bike's engine should be at normal running temperature and also tht the throttle should be in fully open position.
Your bike's engine has a compression ratio of 9:4:1
here is a guide frm compression ratio to psi :-
8>1 = 102.9 psi
8.5>1= 102.9 - 110.25 psi
9>1= 110.25 - 117.6 psi
9.5>1= 117.6 - 124.95 psi
10>1= 124.95 - 132.65 psi
10.5>1= 132.3 - 139.65 psi
11>1= 139.65 - 147 psi
11.5>1= 147 - 154.35 psi
12>1= 154.35 - 161.7 psi
Hope this helps!

07 Kawasaki 650 Brute Force won't start

Seems like a non seating inlet (or exhaust) valve, the low compression and low mileage, plus backfiring points to this being a possible cause.
One other thing, if the quad has stood for a long time, a tight camshaft has caused a jumped timing belt to mess up the valve timing.
Good Luck - Curious to know what you find!
