YZ144 topend rebuild?

Recommended Posts

Ok, so I have a 2005 Yamaha YZ125 bored to a 144. I did a topend at the end of may but today i went to go check the compression with my hand and started it by pushing very hard, I dont know what this means, will i need a new top end soon? Thanks

Depends who built the top end. My two EG 144s (mo-better and low/mid) measure 205 and 215 psi respectively. I don't know what a standard Athena measures. But yes, definitely buy a compression gauge and check it right.
