Hello, I'm sure that this has been covered in previous threads, but my search has turned up nothing. When performing a leak down test should the bike be warmed up prior to test. I have a clymer manual that says that is should be. I just want to know if this is correct. The shop that performed a leak down on my YZ426 F (01) said it should be cold and it was I hauled it about 20 miles in 30 degree weather. Would this affect the out come of the test? I was told that the motor was @ 11%. Thank you for your time and Knowledge.
