How do I know if I need my ATV valves adjusted?

How To Tell if Your Valves Need Checking

1. You’ll hear a distinct clatter from the valve area – this points to lose valves.
2. At times you might hear a click sound while idling.
3. You may notice a subtle loss of power (compression).
4. The bike could start overheating.
5. The intake valves tend to get tighter.

How long does it take to adjust valves?

Pros bill for half an hour to an hour. If you haven’t done it before it’s going to take you longer than 20/45 minutes. The time going to vary based on how many are out of spec. If you have to adjust all 16 it’s going to take you longer than if you only have to do 2.

Is a valve adjustment expensive?

So how much does a valve adjustment or check cost? Generally speaking the average valve adjustment cost is around $300. However, valve adjustment cost depends on the type of bike that you ride, the amount of valves that your engine has, and whether those valves are operated by overhead cams or pushrods.

Why do valves need to be adjusted?

You need to adjust the valves because, over time, due to mechanical wear the clearance between these two parts changes. Typically it gets bigger over time, which causes the valve train to clatter and the valves to not open quite as far as they should.

How important is valve adjustment?

They have two tasks: Valves seal the combustion chamber, and either admit air and fuel into the engine (intake valves) or let exhaust gases escape (exhaust valves). The reason valve adjustments are important is because the constant slamming of the valve causes it to recede ever-deeper into the head.

Can valves cause high compression?

Worn piston rings and/or burned valves. Higher compression readings are caused by carbon deposits that are stuck to the top of the pistons. A compression test reveals the condition of your engine’s valves, its valve seats, and piston rings and whether these parts are wearing evenly.
