You indicate that you have only ridden it 1 hour, then had to rebuild the top end and replate the cylinder. Did the engine seize during your 1st hour of use?

It's a year old, I'm it's second owner. It's seems it's been massively abused.
Yes the engine over heated and may have seized in that hour. But I know now why...............
Just took it apart, found the impeller in two peices, and the mechanical seal fecked!!! Could'nt get the impeller screw out?? Whats the trick? The water pump drive shaft bearing is a bit nasty too.
So this is what I'm assuming happened........
Nasty cheep impeller broke which bounced and damaged the mechanical seal. Lack of coolant flow caused the engine to over heat and with the added induction of water, drawn in the exhaust port/power valve then cased the plating to be damaged in the cylinder.
What do you think?
Also when I drained the gearbox oil, about 1.5 leaters of water came out, it's a propper mess in there. Whare shoud I go from here?
