I will try to get the people from the other forum here. The best forum so far for FT500 was the yahoo group which now sadly is closed.

I am really interested in knowing more about the "plug" for the hole in the cylinder that the tacho leaves when you remove it. Do you have a good link for somewhere I can buy it? I live in Sweden, so a European site is preferable.

I checked my old orders and I believe it's this part:
https://www.cmsnl.com/products/cap-head-cover_12316473000/#.XoWG5ogzbIU
only 3 euros and they deliver everywhere in the world.
It's number 2 on this diagram so it is actually meant to plug this hole:

Might be worthwile to order some more parts with them because of the postal fees.

By the way if you are going to replace your exhaust studs. Order these, these are the correct length FT500 ones (XL500 ones are shorter)

If any of you has the starter side of the FT500 open and could check for play on the starter gears that would be awesome!

FT500R:
@Hellblom.
You can see the plug in this picture
The bolt above it is just to plug that bolt hole and doesn't have any other use.

hellblom:
Thanks! I am really wondering though how this plug is attached to the bike, is it made of elastic rubber and is really squeezed into the hole? I wonder because I know there can be quite a lot of oil trying to leak out of that hole, I have a home made plug there now which leaks even though I tried my best to make it tight.

FT500R:
@Hellblom.
It is a I think metal plug with rubber coating. You have to take of the valve cover to mount it in between the valve cover and the cilinder head.
You could also try to source a rubber plug that fits and than make a plate that attaches to the bolthole above to keep it in place.

I opened up the engine of my bike today and as always it is 1 step forward, 2 steps back..
First I had to open the complete left side of the engine to get to the starter gears that I suspected were damaged. Ofcourse this means draining the oil, loosening the left engine cover which of course ripped the gasket.
Then opening the cover in which the gears live. Of course ripping that gasket to..
Who ever designed this at Honda did not have easy maintenance of these gears in mind.

When I took out the gears at least it was instantly clear why there was so much play in the gear system..
There are 3 teeth that have sheared of the first gear and one on both the gears on the reduction gear. I checked the outgoing spline of the startermotor and it is still ok, 1 small mark but nothing serieus.

I started digging around in the engine and found all 3 missing teeth of the first gear. 1 came tumbling out of the oil drain plug, 1 was in the bottom of the left casing the last one found its way into the generator..
