Compression Test for YZ250F

Recommended Posts

I have a 2004 YZ250F and would like to run a compression test.

Can anybody tell me what the PSI reading should be?

Thanks in advance,

Marcio

I heard it's kind of hard to do because of the auto decomp so you have to take the valve cover off and hold the weights out. As far as reading goes I don't know

You need to do a leakdown test, compression tests are rarely accurate on these engines because of the auto-decompression mechanism.
