i did it myself it wasn't hard it took me a little wile to get it right the first time but now it's easy i adjust them every time i service my honda
yea me too i think the factory spec. is too much gap i did mine by feel. i left just enough gap that i could feel slight contact between the rocker and the valve and have had no problems yet doing it this way.Easy to do it yourself..I just wasn't happy with the way it ticked loudly when at the factory spec. Had to do it over at tighter specs.
