couldnt resist the rainy conditions and went for a ride. on the way home it shuts down on me like i ran out of gas, but i had at least half a tank left. I go to start it again and with the compression release pulled in i cant even begin to clear it out. I check to see if it was even pulling in and it is. So i thought i might run this by some of you on here before getting in to it. Oh to save the questions, oil and coolant are both good levels.

Thank you for the info.

Sounds like what happened to my 400 recently. I lost the big end rod bearing, which essentially seized the crank in place. Still workin on fixing it. :banghead:

It depends on what it takes out when it seizes. Which in your case sounds like the big end bearing seized, which is not cheap.

Yeah, not cheap. I'm just rebuilding mine as a 426, since the cost is about the same. Gonna be just shy of $900. If your pison and cylinder are good you can save about half that by reusing the originals.

nope, just got done investigating and the cylinder needs to be redone, new piston, and the bottom bearing to the connecting rod is frozen. the crank seems to be moving fine but who knows what kind of shape it is in. I think i might just put it back together or not and take it to a salvage yard and try to get as much as i can. its got a hydro clutch, er triple clamp, renthal twin wall bars and wb e series exhaust on it, and a new front wheel. Its eitherthis bike or the 06 crf250, and the 250 has new valves on the way. Anybody know what i could get for the yz400 in the condition.

Probably a 1000 since it is not running... but you would make more money parting it out on eBay or something like that, selling little parts at the time adds up.

I wouldn't mind getting the hydro clutch and triple clamps myself.

I highly doubt you'd get more than a few hundred bucks from a salvage yard. You can buy running 400s for $1500 around here, and the motor is the most expensive part. Either fixing it, or parting it out is gonna be your best bet.

Interesting, everything else in Cali is expensive (fuel, homes, land, etc.) but at least you can get decent deals on bikes!

Still got my original '99 400F that I bought new, with damned low hours for it's age. (most parts still original, even sprockets :-o still in decent shape)
That gives me an idea what it's worth, hopefully a bit more than $1500 (I'm thinkin' about selling it)

Everybody wants the new stuff. I just sold my '03 for $2400. 426's can go for about that sometimes, but mostly because of their Green Sticker status. 400's are down the list quite a ways here.

If your '03 was in good shape, that sounds like a good deal to me.
I'm leery about buying used (don't know what it's been thru) but man what a better value than buying new.:-o

It was fair at that price. It was "currently" in good shape, but the chain had only about another half season on it, and the sprockets were finally getting a bit worn. Plus, even though it still ran really well and showed decent leak downs, it had never been opened up, and everything on it was 4 years old with pretty high hours. The buyer knows all that, BTW.

I think I will part it out (got the thing apart already). Is there a place on here where I can get an idea on what to ask for these parts.

Look in the classifieds, and watch eBay. If you're talking about the YZ450, you might also check on some of the shifter kart forums. You could sell the engine in a week over there. Next hottest thing would be the wheels.
