Hello for sell is a running engine removed from a 1978 Honda xr75 model bike. Bike was purchase from a estate sell as is . After adding fuel a few kicks the engine started with ease!!! No odd noises or sounds. The bad was the engine smoked . Trans went in and out of gear and clutch worked. Couldn't ride the bike had flat tires and would not hold air. The smoking may clean up but I never changed the oil or ran it long enough to see a change. When I removed the spark plug it was not oil soaked . No signs of damage or repairs except the chain area is chipped and a bolt is broken on the clutch cover area a common problem pointed in pictures. Splines and crank threads are great! Please ask questions before purchase. Ship lower 48 USA states. Payment must clear 5 days end of sell.
