Great info... :-o :-o

Looks like for me the 86 cylinder would be the best for and application where your wanting to eliminate the power valve. You have the option of lifting the cylinder or raising/the  exhaust or a combination of both and leaves some options for transfers.

7X KX500 Drag championship winner Jeff Grawbarger uses a 86 top end on this bike with a 89-04 bottom end.
Yes, I know the specs.
No, I can't tell you  :lol:

But I will tell you this... Less has been done to this then you might think..
And that bike is freaky fast...
