Project bike! 05 yz250

Rock out! Ya for sure always like to see a masterpiece being built! I would post this in the main forum. Not many people come here.

Im sure all the 2 stoke guys would be more than happy to see this post!

Lol, you call that rough?
Have fun, great bike.

You will love that bike! I have an 06 and it is a blast to ride.
Go over everything and enjoy riding it.
Looks clean to me. Congrats!

If it doesn't leak or cause an issue, why replace the case?

Fuel fitting looks fine to me.

That bike needs a LOT of elbow grease!

+1 on fuel fitting. looks like normal.

i'd tear that thing down to the frame and soda blast most of that stuff. will save you a lot of time and come out looking new.

DBerg - I would be tempted to keep the Rekluse. Would be interesting to see how it work in moto. Get some 2006+ YZ250 Forks.

great bikes, I had several yz 250"s, I would inspect trans gears and replace any suspect gears, my 05 & 08 yz's needed new trannys after each season. the jetting is also on the lean side, sand or cool temps would make bikes ping/ detonate, I think 08 went to slightly richer needle taper, that helped but would still detonate in deep sand, 50/50 race gas will fix. like bd said 06 forks are a major upgrade, other than that, great bikes

Looking good man! The track in the background looks bad ass, I am jealous!

Keep us updated!

strange place to break, powervalve area, would not think it would be under heavy stress loads, maybe dropped cly when removed. I have had a few weird things happen to my 08 yz 250 2 stroke. developed a massive air leak, creating a run away lean engine condition, soon as I touched throttle it revved to the moon. checked all the usual suspects, crank seals, head,base,reed gaskets, intake manifold ect. could not find the air leak, swapped carbs with known good running bike, no deal. gave bike to good mechanic friend of mine, he called me up & said, you wont believe what I found, I came to his house, stater side engine case was cracked in a perfect circle all the way around the bearing circumference! never seen anything like it, I raced the bike the week before when it still had the air leak, could barely ride it, did not blow up, but would have if I kept riding it. complete teardown, weld case, good as new.

Yeah, either dropped the cylinder or was tapping on it with a hammer to get it loose. Or maybe dropped the bike on the right side and the pipe got smashed in there and pushed up against it.

Weird about your engine case crack/hole. I did the exact same thing in the exact same place on the same bike. I was dumbfounded because it chunked off on my first couple laps on a sand track where I have never seen a single stone. I wonder if its a weak spot. I JB welded it, and it's fine for years now.

I would calling the guy you bought it from and going down to beat the hell out of him. This happened to me before i bought a 2007 rm 125 for 1,000 in 2012 and then found out the oil plug was stripped and a ton of other problems

Shitty deal man, mucho turds on CL

Yeah little much but somewhat justified I mean when your spending thousands of dollars on something you want to be told the things that are wrong with it. Oh by the way it was the drain bolt it was the case it was cracked because he tightened the drain bolt to much. But I got it fixed by Jr cycle shop and its stronger than it was stock and it looks very good.
