Why does Honda adjust valves?

The importance of correct Honda valve clearances can’t be over-stressed, as it can directly effect the performance and life of the engine. If the valve clearances are excessive, then the efficiency of the engine is reduced because the valves open later and close earlier than they were designed to.

What happens if I don’t adjust my valves?

Too much or too little valve clearance can result in poor performance or a rough idle because the engine can’t “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.

How do I know if my valves need adjusting?

When do I need to have a valve adjustment? You should have your valve lash inspected at manufacturers recommended intervals.

How does valve lash affect performance?

Since the valve cannot move until all the running clearance (valve lash) has been taken up, the amount of valve lash you use affects the engine’s performance. If you decrease the amount of (hot) valve lash, for example, the valve will open slightly sooner, lift higher and close later.

What is Valve clearance?

What are valve clearances? Valve clearances on motorcycle and car engines effectively relate to the gap between the top of the valve stem and the cam that operates it. The inlet valves in the engine open to allow air and fuel into the cylinder, while the exhaust valves let the burnt gases out.
