Is 63-77psi sound right for an 06 650 compression

Way to low.I am guessing here without a manual in font of me but i would say you should have at least 120-150 psi.

Are you holding the throttle wide open when you test?

Unless it is a misprint my 06 Servcie manual says 63-77psi. Yes I held throttle wide open while I did this. I only had universal tester with the rubber tip you hold in the hole. The gauge was reading 100-120psi, but I am sure it is more because alot of pressure was getting my the rubber tip.

The 700 shows 155-170psi. Chris do you know where I can get the proper adapter to screw into the head?

Has to be a misprint.The spark plug hole is 12 mm right?

 

[Desertcat]

12 mm sounds right

 

[sandchris]

I have one with that size.Need it?

 

[Desertcat]

I just measured it and it's 10 mm

 

[sandchris]

I will have to check that I have that end.You have a checker or autozone up by you that will rent you one?

 

[Desertcat]

Great Idea, I will see about renting one. The automotive ones I have won't go that small.

I just got off the phone with Chris from Eastern Arizona AG Center. He looked up the spec and 63-77 psi is a misprint like you thought. The correct spec is 155-170 psi.
