The arrow points to the exhaust. Nice choice on the piston.**Quality**
don't forget to scrape all of the old gaskets off and line up the marks on the cam sprocket for TDC before assmebly!! :)
Good Luck

I wouldn't expect too much from a 4-stroke 200es. It wasn't made for any racing, just a trail basher. You gotta good piston, add a quality pipe, make sure you jet right, and adjust the valves correctly, thats about it.
