You can always add octane booster to your gas. I did on my YZ250 which had 155 psi compression.

You will be fine. If you want add a little RTV sealant where you have no gasket.

Skip the octane booster, it doesn't work worth a crap and is not worth the money. It take in the neighborhood of 200 to 220 PSI static compression numbers before premium will not handle the dynamic compression.

Octane booster stopped the pinging on WOT runs for my YZ.

Yes the EX goes towards the exhaust port on your cylinder.

4oz of oil to 1 gallon of gas is 32:1.
