Hammerhead performance

[@rustyshakle2929]

Did you adjust the valves?

[@TrailJoe]

Yes I made sure the clearance was in-spec, valve timing was in correct, and cleaned the carbon off the valves.

[@ChefBetosAwesomeKetogasms]

Yet you fail to mention the valve clearance # or how to set the timing 😢

[@jerh02official81]

You big bord it to what cc? 171cc?

[@TrailJoe]

We only big bored it 3-5cc over the original 150cc, mainly just to get rid of the smoking. anything over what we did you have to upgrade other parts of the engine.

What kit did you use?

[@TrailJoe]

I got this kit off the hammerhead performance website, I believe it’s 2-8 cc over stock.
