compression tester

helloo today i got a compression tester that was reduced from £99.95 to £40.25 bargain :biggrin: so after work i just had to try it looked at the zed and thought nah **** that shit

 

so i did the test on my n15

 

the results where 137,135,136,134 dunno if thats any good but it sounds ok to me :whistling:

 

 

also did i do the test correct i removed the leads and 1 spark plug at a time and cranked the engine over untill the digital display stopped going any higher ??

On a zed the test is done with all the spark plugs removed,the engine should be hot.And remove the fuel pump fuse also.The manual states to open the throttle but the balance pipe will be off anyway.

Say about 5, 10 is too much. Take the highest reading.
