This is a complete bottom end off a 1982 xr80. The engine mounting locations on the cases are damaged and will need repair as shown. The crank spins over smoothly and the connecting rod is tight with no up and down play in the rod. The transmission shifts smoothly through all the gears on the bench. There is wear on the case at the shifter shaft seal area see photos for details. Kick start splines seem ok and kicked over fine in the bike. The bike held oil and did not leak when it was assembled in the bike. The electrical has not been tested and is not guaranteed. This bottom end is for parts or repair. Fits other years and models but check with dealer prior to purchase please. Please look at the pictures carefully for all details. Parting out whole bike see other listings for more details. Sold as is for parts or repair only. Buyer pays international shipping. Any questions just ask. Thank you.
