Setting your valves is actually pretty easy. Good tools and knowing what you are doing is a prerequisite for the block – even after setting the valves – to run smoothly. Read the text below and watch the video and you will see that it is actually quite simple.

Honda Basics – Valves Set

Although Honda has made reliable mopeds, your plofpony needs some maintenance once in a while. Below we explain what valves mean, when to do it and how to do it. Sometimes you also want to change things make sure you have the right parts. Because you know for sure which parts you need, download our free documentation.

What?
Because the old Hondas are four strokes, they have valves that allow the gasoline and air mixture to flow in controlled and let the exhaustgases go out through the exhaust The cam shaft, which sits in your cylinder head, pushes up a tumbler that presses the it allowing it to open. There is a separate valve for letting in fuel mixture and one for the exhaustgases, so there are two in total. To reduce the wear of the parts in the cylinder head, Honda has built the engineso that there must be a little space between the part of the tumbler that presses the valve and the top of the valve. That room is called the valve clearance. Due to vibration, heat and wear on the bottlenose dolphins and valve stem, the valve clearance gradually changes over time to an incorrect value and then you have to set valves.

When?
According to the booklet of the SS50 it has to be every 3000 kilometers, but with once a year you set your valves you can also get away. If you’re a little lucky, you never have to do it. You often also have a little power loss and you hear some ticking out your head when it is needed.

How?
For valves you only need two tools: a 17mm key, a 9mm key. You can also use feeler buddies, but it should work fine without it.
First, turn the valve caps loose. These are the large caps that sit at the top and bottom of the cylinder head.
Under the valve caps you can see if it is good a kind of square rod with a small nut around it. When your valve clearance is good, you can move it to the left and right, but not from top to bottom. If this is already the case, you should stay off it. If you can move them from top to bottom (too loose) or not from left to right (too tight), you have to loosen the nut. Now you can turn the square rod. If valves are too tight, turn it off until they move properly (not up and down, but to the left and right). Tighten the nut and see if they’re still not right. If not, then loosen the nut and turn the rod. The same procedure applies to valves that areittoo loose, but then you have to turn the rod more in or out.

Behind the links below you will see a video in which you can see how to put valves and you will also find the link to the tool you need.
