Probably one of the most informative, step by step-by-step videos I've watched. Usually, ppl go too fast, or their camera angle sucks. It's not too often I subscribe to someone's channel, but I will just because of this video!

[@HorsepowerHouse]

I have tons of videos like this regarding motorcycles. Dirt bikes ATV's cars etc. make sure you see the thanks button underneath the video screen.

After you had it all together, and turned the shaft, I didn't see the side power valves open, why? Mine dont open either. I cant see what i'm missing .

[@HorsepowerHouse]

It worked fine. 100%

[@HorsepowerHouse]

The rod is bent if the valve does not freely move.
