Weird knocking..

Recommended Posts

So I just did the top end, and I kicked it over slowly and there's a little knock. Timing was set properly, so what could it possibly be?

is it a knock or a tick?

If its a tick, a shim could have fallen out of place while reinstalling everything?

It's the decompression pin which is totally normal. Once the RPM's go up, that noise stops. It's operated by centrifical force with a counter weight and a spring. If you pull the valve cover and watch the camshaft spin, when it gets to the decompression pin, you'll hear and see it. It's fine.
