Eric Gorr yz144 compression change?

[kevinyz144]

Hey guys I just bought a 07 yz125 with a EG 144 kit. it's set to run on straight race fuel and that can be quite expensive when ripping a lot so I was wondering if I could buy a new cylinder head or something to lower the compression so I could run it on standard pump gas. I was looking at a athena cylinder head because they make 144 kits so I was thinking I could buy a 144 athena cylinder head but I'm not sure if thatll fit my cylinder or work correctly with EGs 144 kit. Thank you guys

I'd call EG directly.  He'll set you straight on what you need.  He's also very helpful in answering these types of questions.

I would contact gorr he'll most likely be able to sale you a proper oem head correctly modded for what an athena head costs.
