Important to do the test on both a cold and hot engine, but those figures look OK. As Kit said its more about them being similar. If there is a problem one of them is usually way out e.g. 135, 95, 140, so the bad news is easy to spotAnyone know what values you have got or should be getting from a compression test on a 1996 speed triple?
Mine are 135 , 130ish , and 140 from left to right. Hows that sound.
I'm no expert on this, but there's a flaw in calculating real or effective compression in this way that I've read about.If I read this right compression ratio for your bike is the same as mine @ 10.6 to 1
and 1 being atmopheric pressure then you should get around...
10.6 X 14.7=155.82psi or Kpa being 101.4 X 10.6= 1074.84Kpa
It's not exact but it should give you a ball park figure.
Squirt a little oil into each cylinder and make sure throttle is fully open.
Do another test.
