Very strange '01 426????

I accidently posted under WR earlier.

My son went riding today. Came back, and told me that the bike ran great until it just died (locked up). He said it was really hard to get the kick started to move but was finally able to get it to kick over and eventually start. He said it ran perfect? for 10mins idle and then he rode it over some whoops and the same thing happened. I went out to the shed (its dark now). It feels different kicking it over now, somehow out of time? It almost seems I can't get a full kick out of it without compression building at the bottom of the kick? Sounds like timing skipped? Is that possible on this bike? If not what could it be? How much to fix? Or is it simple? Sure does not sound good from what he told me and what I have felt out in the dark.

Mine 01 did something like that. It was the main rode bearing . when it heated up it would lock up .

This bike has apparently had the top end rebuilt too, however we have ridden it probably 20 hours since rebuilt. Or more. Just can't understand his explanation. I can't see the thing seizing like he said then starting again?

It gets a bad spot in it . It just spins free till it gets to a hard spot then with a lil bit of playen wit it will free up .:ride:

"It gets a bad spot in it . It just spins free till it gets to a hard spot then with a lil bit of playen wit it will free up . "

That is basically what he said happened. But why? Do I need to rebuild the damn thing...again. I swear I have never had a more tempremental 4 stroke before. I think I will go back to 2 strokes after this thing. I guess I have to go out therej and start tearing it apart!

u can send off the crank and get it fixed r get a new r used on off of ebay but there pricey.

I guess I was in denial. It is the only thing that matches what the kid said. I have no light where it is at and can't get to it in the light until tomorrow. I can't believe he cooked it.

Can you repeat that in English, please? It might be worth reading.

Sounds like a big end bearing.... not a bad job, but parts are not cheap.
