Complete bottom end off a 2006 crf80f in great shape off a running bike no noises cranks in the cases but there is damage to the case on the shift shaft housing where the seal sits. See pictures for details. Repair it or use as it is. I am unsure if it leaks oil at the shifter shaft seal as i did not have the bike together for more than 1 day to notice a leak. It did not leak the little time I had it together. Was removed from a running and driving bike with no smoke or weird noises. Comes with timing chain that appears to be in good condition. Comes as pictured with everything pictured. Parting out whole bike see other listings for more details. Any questions ask anytime.
