How can you tell what year your KX500 cylinder is?
89-04 is easy.
If you have a 3 valve set up it's 89-04 and they are all the same.

Here's where it gets a bit more tricky.
86-88 kx500's all have two valves,

So, how can we ID the 86-88 cylinders?
The 88 is the only year of the 3 that uses 8mm standard head studs like this:

Both 86 and 87 use counter bored studs like this:

And the 88 kx500 cylinder is the only year that has KIPS in raised letters like this:

Both 86-87 have a sticker on the side.
No sticker is shown but it's suppose to be there

So how can you tell the 86 from the 87 cylinder?
Apart from the exhaust degree timing there is a easy visual way.
Take a look at this 87, note the compression reliefs on the kips valve ports:

Now take a look at the 86 kx500 kips ports, note that there is no KIPS compression reliefs:

So that should help you out.
There may be other visual ID difference as well, but these are the ones I know about.
