Hey guys it's my first post here, sorry if it gets a little long but please bear with me. Just had a quick question about my 2001 yz125. I am putting a new Athena cylinder kit onto my bike, seeing as my old cylinder was shot from the previous owner. I was going to get it replated but the cost was going to be more than the Athena kit... So I recently got the whole kit in the mail and I already got the piston on. My question is, the Athena gasket kit came with 2 different base gaskets, one is black and looks like the OEM base gasket. The other is green and looks cut out. I have searched the internet for a while and found no clear answer to this. Do I put both gaskets on like the kit included or just one or the other? I know my service manual shows just one gasket but I want to know before I torque the cylinder down. Thanks in advance

The Shop
Specifically designed for the pro, semi-pro and amateur rider who freshens up their engine prior to a race or during mid season
Kit includes a top of the line MLSS head gasket and premium quality base gaskets of different thicknesses to optimize engine compression ratios
Gives the rider a choice of using standard gas with stock compression or race gas with a higher compression
The black and blue base gasket should give you the squish you need. I've built a few bikes with this kit and they all work out spot on with that gasket.
Make sure you check your ring end gap, I've had a few of the Athena rings come in a little tight and need to be filed down.
Good choice, that cylinder makes a big difference on those YZs. I found the stock Yamaha pipe with a PC Factory Sound silencer works really well with it.
