can you do a compression check on a raptor? I was thinking that the decompression pin would give you a false reading.

 

someone gotta know?

 

a million people with raptors and nobody knows!

 

Yes you can, im pritty sure you can do it with any engine cylender

 

Yes but you either have to use a battery charger or connect your battery to a larger one. It takes some RPM to get past the decompression mechanism. My CR730 has 175 lbs of compression when using a Grizzly battery and holding the throttle open, YMMV.

 

i know the decompression pin would release some untill the motor reaches a certain rpm.
