Posted August 1, 201114 yr hi guys, i've recently had some issues with my new bike. keeps spluttering on the power band and when you try to maintain your speed! i've changed the plug for a 8 instead of the 9, new air filter and new 2 storke oil. i ran it down to my local bike shop today and asked them to give it a quick compression test. it was only a young lad who did so was a bit uncertain if he knew what the comp should be! this is how he did it, and the results:- ingnition on, 3 pulls on the throtle. then 3 kicks where it reached 140 psi. then 3 more where it made 160 psi was the correct method and are those good results?? i'm certain a red up on here it should be around 150 psi on a new engine? btw the bikes a 2003 dtr with 13,000. never been rebuilt any help would be great! thanks josh

But thats good comression you have anyway. Over 120+psi is grand EDIT: change the plug back to 9, unless you live up on top of a very very high mountain.
