SALE PENDING. I tore the motor down and replaced most of the bearings in the crankcase (crankshaft, balancer, input and output shaft bearings). All brand new valves, valve seals, and the valve seats were just done. Newish piston rings. Nearly new tires (MT43 front, D606 rear). New chain, front and rear sprockets. New manual cam chain tensioner (the bike came to me because the previous automatic tensioner appears to have failed). New throttle cables. New bearings in the rear wheel. New pro-X gaskets used in the rebuild.... No, I'm not a red seal mechanic. Yes, I've done this before, this is the fifth DRZ motor I've put back together after splitting the crankcases. Yes, I will warranty my work if the bike sells for my asking price. more details at https://tbrown.ca/blog/dr-z-400s-for-sale/
