This motor has the rotating assembly (pistons and crank), clutch, stator, starter, oil and coolant pumps, and all are in good working condition. I was parting out the motor when i removed the head and noticed that the valve stem was bent and the spring was broken. the rest of the motor works perfectly. the photos show the clutch removed, but i assure you, it is completely intact and works as advertised. what that means is that if you have a good head from a motor that has a spun rod bearing or worn out rings or something like that, you can take the head and gearbox from your other engine and bolt it onto this one and it'll fire right up, provided that you install it correctly. if you try and buy a used motor complete on ebay or somewhere else, you will literally spend double what i'm selling this motor for. this is for local pickup only, and you can see the bike it came out of to see that it's in good condition, never been wrecked. all the motor mounts are intact. i am missing the clutch cover and stator cover because they were the first to sell when i had intended to part out this bike.
