I no my local shop put a CR style thin head gasket on my 250r when they port and polished with head modify. But i can't remember the year i think 89 CR am I right. The reason im asking here and not phoneing is because they are rather busy. Thanks.

 

The '89 CR250 head gasket (ten thousands thick) is one possibility and the most common. The other is the '85 ATC250R head gasket (about 18 thousands thick). The stock 250R 3-piece gasket is 30 thousands.

 

CR Head gasket, 1989 model year: .017" thick
ATC250R gasket .045" thick
TRX250R gasket .055" thick

 

thanks

 

I knew Backcountry would have the exact info. I just went to the garage and measured my old ones hanging around, but it's better when someone has the exact numbers (I'm writing them down for future reference).
