ANOTHER DUMB QUESTION
BigGreenMachine:
Yeah I found an old post by you saying you were running the new style head gasket. Surprised that it fit myself but very happy to hear.
The whole cylinder/powervalve setup should bolt up without mods, very happy to hear and will be looking for an updated cylinder when I rebuild my motor.

Can you link that old post? That could be an error on my part. My bike is running the standard 87 head gasket which is diff, from the 89-04 head gaskets.

You said you had an 89-04 head gasket on your 87 for a year.

Thanks for posting that. Sorry I was incorrect about the using the same head gasket as the 89-04 units. They are way diff. from my 87 head and gasket and wouldn't work. I'll correct that older post. Thanks.

The general configurtation of the base gasket is the same, with the exception of the extra KIPS shaft, so you could probably use a newer gasket on a older bike, but couldn't go the other way. If you were going to use a newer cylinder on an older bike, you could use an aluminum epoxy, or have the crankcases welded to support the additional KIPS shaft, use a newer cylinder and head, and the KIPS actuation arm would have to be changed, the newer pin is smaller.
So by the time you've done all this, it may be cheaper to buy a newer motor slip it in your bike and be happy.
