How much compression should a 125 2-stroke have?
Minimum 2 Stroke Compression Chart Good compression is 150-160 PSI. A 125cc 2-stroke dirt bike should have at least 140 PSI and about 180 with a fresh top-end. A 250cc 2 stroke should have 170 PSI or more and 210 PSI when new.
What causes low compression on a 2 stroke?
Worn piston rings can cause incomplete sealing, resulting in lower compression and more difficulty in starting. Worn piston rings or reed valves that are no longer sealing properly may be the cause of the poor startability characteristic.

What kind of engine has high compression ratio?
We know that Mazda’s new Skyactiv-X “ Holy Grail ” engine is high compression, along with Infiniti’s “ diesel slayer ” and Toyota’s “ Dynamic Force ” series that all advertise more power along with more efficiency. We live in an age where engineers can’t just give an engine more power by making it bigger.

How do you calculate the compression ratio of a cylinder?
Add up your measurements and divide by however many you took (usually three or four is plenty) to get the average diameter. Divide this measurement by 2 to achieve the average radius of the bore. Step 3: Calculate the cylinder measurement. Using an accurate ruler or tape measure, measure the height of the cylinder.
What kind of power does a Kawasaki KX125 have?
The KX is closer to the CR125 ‘s mid-and-up in the social strata of screamers. The KX125 does nothing down low. All the power comes on in the middle. Unfortunately, Kawasaki’s upper-end hook doesn’t go as far or fast as Yamaha ‘s and KTM ‘s.
Why is my Kawasaki KX125 so stiff?
Stiff. Kawasaki’s SASS (Speed Activated Spring System), or bladder fork as it is known to the rest of the world, is in its second year, and Kayaba made a few changes to it. The biggest change is that they decreased the amount of air in the system by raising the oil level 20mm. This alone could be the cause of the stiffness. How do they work?
