Compression??

[yamaman700]

What is the normal cylinder compression on a non power valve 700 triple??

Cant tell ya what a fresh 700 has, but mine with close to 10,000kilometers is 126 across , checked the compression Saturday.If we dont get more snow soon, I am gonna do the top end for some preventative maintanence.

Not a bad idea bd with thos amount of miles,,wile there is no snow.

Gave her a test, actually had to do it twice because she is only showing 100 across all three!! That's with the engine warm and with it cold she showed 105. I was a little surprised cause it seems to run so well. Any thoughts. There's less than 5000 kms on the machine.

At least there consistent thats the main thing,is your gauge reading right??

it should be higher than that yes..

135 is a good cold and new perssure for a stocker
Checked mine before I had ever started it, and it was 133 at 5500 mi

I agree with daman, I had a Matco gauge that was reading incorrectly (low)

 

[yamaman700]

checked it again with a different adapter and got about 126 across all three warm. That's better!! I asssume the adapter was the problem. I checked the gauge with my compressor and it was right on.
Thanks for the information guys....

Glad to hear,,she looks healthy..

did you have the throttle wide open when testing???
