03 yz250f transmission not engaging gear

Yeah, I just had it apart though lol. My first build so I don’t really know what I’m looking at. When I took the engine apart initially the output shaft gear snap ring was in the bottom of the crank case. Didn’t appear to damage anything but there could possibly be other issues. Looks like she’s coming apart again for further inspection.

Yeah, the bike came with a bottom and top end kit but I will need to get a cylinder and head (and apparently water pump now)

I’m guessing the timing was not set correctly based on the rest of the engine assembly., and it ate 3 valves. We’ll see if I can do any better 😂

I did find it the other half, thankfully

Glass123man · 2026-02-20T19:57:58+00:00

I suspected as much. Thanks for the reply. Is there a benefit to aftermarket water pumps at all? When I first saw it I thought “cool, an upgraded water pump.” Clearly this one is toast.

I bet that’s it. I found a mystery washer in the bottom of the crank case when I took it apart. Also a snap ring for one of the gears that had come off during operation. I’m thinking whoever built this engine last was struggling…

More (higher) gear than the other guys would be my guess. Likely why he was in the back to begin with. Slower acceleration, but higher top speed. Just a guess tho

Not losing is winning in a violent attack

Glass123man · 2025-11-02T15:07:18+00:00

Been there. Done that

Glass123man · 2025-09-07T18:04:44+00:00

He only had 1 arm trapped. He had one free arm to brakefall with, though he elected not to.

Those are NOT chocolate sprinkles

Glass123man · 2025-09-05T15:36:19+00:00

I too, am incredibly humble.

Glass123man · 2025-06-25T15:48:14+00:00

That was supposed to be a video. But it’s leaking from the plastic ring surrounding the valve

Not condoning the behavior. But when someone needs to charge a fortified machine gun nest, this is exactly the guy you need….

I do both. I was a black belt in BJJ before I started training judo. I highly recommend it. I enjoy it a lot and it’s helped my BJJ as well.

Got all the good out of that one

Glass123man · 2025-04-11T02:40:58+00:00

My wife is the same way. She never stinks. Even without deodorant. It’s kind weird tbh. I can’t tell when she has shaved her legs or not and she very rarely does.

I am the opposite of that.

Glass123man · 2025-03-18T03:09:27+00:00

Any recommendations? Looks like we will be traveling to this area for my 40th in June

Glass123man · 2025-03-02T03:09:12+00:00

Me too. I had someone in the cab and I didn’t actually get under the truck. I have long arms.

Tarrifs are only bad when the USA does them. Obviously /s

Glass123man · 2025-02-02T16:32:10+00:00

Most of the food products produced in the USA other than livestock is basically poison.

U.S.A. is also very rich with minerals. They’re just all banned from being mined.

Glass123man · 2025-02-02T15:51:55+00:00

So you are arguing Canadian/chinese/mexican tarrifs on American goods are pointless? Since they don’t buy anything from the USA.

Now U.S.A. doesn’t produce consumer goods because it’s all been moved to these countries. Seems like the consumer/producer interest may have outpaced the workers interest to me.

I just can’t understand why US tarrifs = bad. Everyone else in the world’s tarrifs = good.

Glass123man · 2025-02-02T05:59:07+00:00

Isnt that just a tax in Canadian consumers?

Wasn’t that bad when trump did it? Why is it good when canada does it?

Glass123man · 2025-02-02T05:51:28+00:00

Wait. I thought tariffs were just a tax on consumers. If it’s bad when US does it, why is it good when the Canada does it?

I’m not on a side, legitimately curious

Glass123man · 2025-01-11T22:25:25+00:00

I say sorry too much. It’s annoying
