engine locked up

[nadroj]

this morning when I was riding my ht the engine all of the sudden locked up while going up a hill.
I had been hearing a metalic ticking in the engine recently.
Where should I begin to look?
I think the rings may have given out.

Is this a Chinese frame mounted engine?

FIRST<, Have a look here to make sure your chain is not jammed.

If Your chain is not jammed.... & your engine IS locked up, you will have to pull off the head & have a look inside.

Let us know what you find. Post pics if possible.

good luck

I know for a fact it was the engine not the chain because when I pull the clutch in I can ride. Should I go ahead and pull the cyclinder off, also?

oh yeah I have been riding this for about 9mo and with out an air filter and I ride hard, so I am surprised it lasted this long.

Yeah, might as well have a good look at the insides. You'll know if the rings are seized, soon.

hahaha.... no regrets, I see.

ticking.... could be the wristpin bushing/bearing. when you get in there, check your piston for 'up & down' play.

ticking could also be your main bearings....?

Yeah It almost sounded like lifter tick but i know thats not it. I will check tonight.

How do you take off the cylinder??

One nut at a time lol.... Remove the muffler (2 nuts, maybe 3), remove the intake/carb (2 nuts), then the cylinder head (4 nuts) the cylinder should slide up.

9 mths & riding hard without a filter.............scratch one little engine.

Riding without an air cleaner with one of these engines is certain death. The intake is pretty much inline with debris being slung around by the rear tire. The frame is in the way, but plenty of fine dirt is being kicked up and sucked into the engine.
