    **UPDATE **

    Rolling chassis - engine has been removed from frame

    Details of crash damage:

    My wife lowsided T3 at Canaan Speedway as a result of transmission failure. About 30mph. The only part that needs to be replaced is the upper left fairing bracket - an aluminum tube with a 90deg bend. I was going to make one out of 5051 alloy (high ductility). Other than that, just scrapes and scratches. The cracked tail section is the worst of it.


    Details of power unit condition:

    The engine is out of the bike and disassembled. The trans failure cracked the left engine case. I bought a second lower end for the case half and trans. I got as far as rebuilding the crank with a Hot Rods connecting rod kit. The piston has about 25 hrs on it. I have rings and gaskets. The second lower end had also been used for a "no cut" RS repower, so it has the modified right case and clutch cover.

    Thanks for looking
