When you first kick it, i heard the noise of a broken bearing, so i was sure that it would be either the connecting rod or main crankshaft bearing. After 40 years of repairing that kind of stuff, your ears are well trained!!! The reason for that bearing to break, well age certainly, on the racing Aprillia bikes we ran the main bearings were rated for 1000km at 14500 rpm. So if the owner of that bike didn't use high grade oil, or not well mixed premix, or forget to put oil in gas sometimes, that kind of thing would happen. Those dirt bikes need a serious attention, no made for a casual user without any mechanical knowledge.

Nice find! I always wanted a YZ-WR for a trail bike. If you didn't already know the "wide ratio" on the side is referring to the gearbox. This bike was marketed to enduro riders and had taller gears and a heavier flywheel to facilitate a smoother onset of power and added inertia to keep it from stalling while climing hills and starting from a dead stop. It was basically an answer to the KDX from Kawa. Yamaha did have a 2 stroke trail bike prior to this that was called the "IT". Talking about it makes me want one again!

Joe, I seen that the bike has a lighting coil / single yellow wire. Check out the vin # again. I believe you have a 1990 WR250 . That has a wide ratio transmission and a lighting coil. WR's are sought after. Worth a rebuild kit. That is a clean 35 year old bike. I have had many wr /yz's . Ball hone that cylinder. If above the exhaust port has zero scratches, should just get a pro-X "D" sized piston. Yes a D is over sized only by 0.04 th. In. Size the rings . Should have another 30 years on the old girl... And get a TM- carburetor for her , she deserves it. E-bay carburetor sucks ....

I used to ride a '75 Honda Elsinore and '80 CR 250...also dabbled with the Suzuki RM's and Yamaha YZ's but didn't like them as much.

@wmden1 2 ай бұрын

Brought back many memories. Thank you, and nice job. I've done similar tear downs myself. A few of the older, as in 50s and 60s German small bikes, sold by Sears, were built with roller transmission shaft bearings that had the inner race pressed on the shaft, or the inner race was the shaft itself, and the outer race pressed in the case. When you split the case, the rollers just fell out loose, both ends. They were much fun to put the cases back together. It took some really stiff grease to hold the rollers in place until all was back together. I was about 13 to 14 years old. It was a good, fun learning experience. I did learn to appreciate the larger Hondas that the cases split top and bottom and had regular bearings. They were a breeze.

Hi Joe, when it is noticeable when being kicked over that there is something wrong, don't turn the motor anymore and when you see that much metal in the intake and exhaust, it's definitely motor out and split, it's also easier on the bench.
