Hi All (I think this is the appropriate section?)
My bike had some overheating issues last season due to some issues with the coolant system (all taken care of now). I haven't had a chance to run the bike through its paces since the season ended so I decided to run a compression test to see if everything is ok inside.
Rented a tester from O'Reilly's (had to buy an adapter for our tiny threads) and my numbers were as follows
Cyl 1: 150 psi
Cyl 2: 150 psi
Cyl 3: 149 psi
Cyl 4: 146 psi
(2006 CBR600RR, basically stock motor, unknown miles)
Now my question is this, are these numbers ok? I've read different things online, like I should be around the 150psi mark, but the service manual says 178 psi. However I've also seen that the number could be lower depending on the tester itself and that I can't be 100% unless I did a leak down test or something of that sort.
I know that you want each cylinder to be within 5% of the others (7.5psi in my case) and I at least have consistency across the board.
Any reason for concern or should I be ok?
Thanks
