Engine rebuilt, ran fine then locked up solid!

Recommended Posts

Just finished rebuilding my XR400.

It was a full strip down with new oversize piston 1mm.

It was running sweet for a good 20-25mins of gentle road riding then out of nowhere the lights dimmed and it just cut out.

The Kickstarter was jammed solid and I was forced to push it all the way home!

When I got back I tried turning it over with a 17mm socket, it was solid but when I turned it the other way it free'd it up and was then able to turn counter clock wise again. It seems to turn over fine now but I haven't tried to start it incase there's any damage or reason to this.

I can't understand what could have happened for it to do this. It was running fine but i did notice a strange noise when at low RPM and giving it full throttle, it was making a couple of chirping sounds then it would go, again this was only at low RPM and giving it full throttle.

Any ideas?

Absolutely gutted!

Thanks

Get a look at the cam lobes for a start. If they look scored , you weren't pumping oil. Then the damage gets much worse.
