Installing the valves into the Honda Benly 150 head is a bit tricky. They are so far down into the casting that it's a challenge to get tools down on the springs. Here is how this works:
  • Each valve must be firmly against its seat with a clamp
  • The valve spring retainer must be pushed down on the spring past the indent on the stems end
  • The "keepers" or "keys" as I will call them, must be pushed into place one at a time
The first valve took me 20 minutes to figure out the process with the right tools that I had on hand. This was no easy task as I neglected to go through the hassle of finding a valve spring compressor that would actually fit this little cylinder head. I used a clamp to hold the valve in place just as shown below.
