2001 YZ250F - Basket Case ...

Recommended Posts

Hello,

I have a chance to purchase a “Basket Case” 2001 YZ250F for $400.00 or best offer.

It is literally torn completely down. It had blown a Rod and put it through the Cylinder.

The guy took the bike completely apart as well as the Motor. All of it is in a basket.

He says the bike is in good shape except for the motor. He claims all it needs is a

new cylinder, rod, piston, Valves, and rings.

I need to respond to this offer TODAY.

My question is this:

Will this be worth buying for $300.00-$400.00 and replacing the parts and putting it back together. Now I have experience with 4-strokes; however, I have never worked one of these high rev. motors or taken one apart … also been 2-strokes, and older 4-strokes.

Will I be getting myself in over my head (I do not feel I would be) … I am not in a big hurry to get it back together and I would reply on many of you people to get answers as I do put it back together?

What manual is going to be the most comprehensive and best for this project?

I would think I would be spending another $1000.00 to get this bike back together … does that sound about right? I do not have a problem with that since; when I get done with it I would have a New Motor on a fairly newer bike frame.

Thoughts please ….

Thanks,

PeteWolf

I dont know i supose if that is all that it needs, not valves (most likely will) then maybe but only if you know the plastics, frame, suspension, everything is in good shape, they dont sell for much more then 2000 so make sure if you plan on re-selling, you budget the rebuild. A personal experence was a friend of mine bought an 06 250r for 500 dollars that had caught on fire, needed ALL the plastic replaced and the seat, all the wiring, air box, air filter, rear tire, and the carb was torn apart and cleaned, and it took forever to clean up the frame, but once it was done it runs great and you couldnt tell it was in a fire, but in your case, the bike probably has quite a bit of wear on it and if he blew the engine he most likely rode hard so i woulndt be suprised if the valves are shot $$$$, i would just look for a used motor instead to bolt on instead of risking dumping a whole lot of money into that motor only to find it needs more parts.

I forgot to mention Valves too ... they would need replaced as well... so I

am told.

A motor would cost me .... about how much would be a good price?

$500.00???

Thanks

I would say that if you're not afraid to spend at least 1000, but hopefully not more that 1500 on it, then you'll be happy when you're done with it.

Count on replacing the crank assy & main bearings, cam chain, all 5 valves & all 5 valve springs, cylinder, piston, rings, & all the seals & a gasket kit.

Super clean everything inside the engine, and also clean out the oil tank in the frame & the oil lines going between the frame & the engine to get all the metal out of them. You might need a new oil pump too, depending on how much metal it ate. Check the cams in the head to make sure they aren't galled where they ride in the head. If the head is messed up, it'll cost you more. While you're in there, put in a '03 or later exhaust cam and you'll have auto decompression, and it'll be easier to kick (unless that's already been done).

Oh, get the factory Yamaha owners manual for that model year. They are great for doing an engine rebuild.

Good Luck!!!!

I think its worth it. The front and rear suspension, frame and wheelsets alone are worth more than $400.

I am in the process of completely tearing down and rebuilding my 2001 yz250f, so if you do end up getting this project bike, feel free to contact me with questions. Im sure I will run into a lot of the same issues you will encounter.

Goodluck!

Thank You MUCH for the very informative post. I will need to take a 2-1/2 hour drive to check this bike out and get it, but base on your post I will be doing it today.

I will keep you posted on what I find/get.

I kinda thought the same thing. Even if I didn't rebuild it ... parting it out on Ebay

should make a few more bucks then what I pay for it.

Maybe you can PM your email to me so we exchange info while rebuilding. Not that I would have much to offer you in experience ... but two, three, four, or a Forum is Always Better than one.

Thanks for the reply.

I ended up getting the "basket case" for $300.00. It wasn't as in good as shape as the seller claimed. The sprockets were worn down so far the chain could have easily split over the teeth. I told him, anybody who would ever let there sprockets get that bad DOES NOT take care of his bike and rides it until it brakes ... like this one.

Still have yet to evaluate if all the motor parts are in deed in the basket. So, still not quite sure if I will be rebuilding or parting it out.

Did the 2001 come with inserted seats in the head on these bikes?

I'm not sure about the valve seat question. My guess is yes, but I'm guessing.

I take it the valve seats are hammered?
