Recommended Posts

This guy has a 03 kx250 that he would sell me for $800 just the bottom end needs to be rebuilt. How much do yall think it would cost to rebuild the bottom end

it's never "just" whatever they say it is. There's always more and that's all the seller is willing to admit too.

 

Will you be doing it on your own or paying a mechanic? Huge difference

Generally, when the crankshaft goes, so does the piston and inside cylinder walls.  Without seeing it, I would personally budget $800 for just the engine.  This is with me doing the work besides replating.  I would also be concerned that the forks need to be rebuilt, shock needs to be rebuilt, chain/sprockets replaced, tires worn out?, swingarm/linkage bearings, clutch, etc.

 

All KX's are high maintenance and high performance off-road vehicles.  If you think to yourself, "All I want to do is just ride around some", please be aware that the previous owner did too.  He "just rode it around some" until he rode it into the ground. He was focused on riding, not wrenching.

 

Do yourself a huge favor.  Save up more money and buy one that runs.  I know that "just $800" sounds tempting, but the final running price and trouble is a good bit more than just buying one that is already running.

 

There is NO WAY IN HELL someone should buy an 11 year old blown up bottom end bike for that much.

Personally if the rest of the bikes good I would buy it for 550-600. I would offer 500 and see what he says. I'm never afraid to lowball on a non running bike because a lot of the time they know there are more issues so they drop it way down.

Don't run a wiseco crank, they are tempting, but they are garbage. I've ran one before I knew better, won't be running again. Maybe one day wiseco will up their crank quality, but not anytime soon.

Make sure it hasn't been sitting for ages otherwise other stuff could be messed up.

Needing a full rebuild on the engine like that.. I'd be more inclined to 500.  If he doesn't take it just pass on it.  He says firm hoping someone will pay up that much, but busted bikes are a hard sell it seems, with so many non busted ones for not much more...

If I did get it would the hot rods complete bottom end kit be the best?

 

 

You'll get differing opinions on this, but the Hot Rods crank that's currently in my KX250 has over 200 hours on it, and that's more hours than I got from the OEM crank.
