I know the trans definitely fits, I have the 4th and 5th gears in mine. It was actually offered as a wide ratio kit through kawasaki. The ignition was offered in kit form also, for lights and the heavier flywheel. My 86 has a cracked but welded up clutch cover but I noticed a bunch of nice Tecate clutch covers and powervalves on Ebay. I also read somewhere that the cover gasket is the same between the KX and the Tecate. I may chance it and get them, they were relatively inexpensive. Thanks for the help.
