Can I use a stock head gasket?

[Yamaha or walk]

I have a 2001 blaster. I got a cylinder, head, and piston off ebay to make it a 67.5mm and couldn't find a set of gaskets for it. Can I use stock gaskets? I'm specifically asking about the head gasket. Yes I know I should have just bought a brand new kit for it but don't have that kind of money. Thanks for any feed back.

If you are intending to use the old gaskets I would not recommend it.

Head gaskets may be re used if annealed correctly, a new one is a better choice!

Check to make sure the gasket does not hang over into the bore.. And if you re use the old one you will need to anneal it as stated.

Thanks for the input guys. So it seems by the video by SpeedySlider I should be fine with a stock one at 67.5mm but I will double check it to make sure it will not be hanging over. Also no I'm not going to use the original one, I got a new one that is stock size

You will need to trim a stock sized gasket. i did mine with sand paper, took some time but it works

my bore is also 67.5 i believe

kens video says 67.5=no modded head gasket/above 67.5mm gasket needs to be modded
