Ok, so I take all my bearings from my yx160 to the bearing shop, and he tells me that some of them are oddball sizes and I'm gonna have a hard time finding replacements. After much googling, I have found these will do the job!
yx160 main bearings, 22x56x15mm. Same as suzuki rm250y output shaft bearing. Most likely other years use the same bearing to.
yx160 gearbox bearing, 17x42x12. Used in xr250 and cr250 elsinore gearbox. Available on ebay.com
I gave up on the needle roller. I think its a poor design, the shaft is noticeably worn in my engine where the rollers run. I'm machining the cases out to suit a 6002 ball bearing. The 6002 is quite a lot smaller than the ball bearing usually fitted in the case cracker yx engines.
The 6203 can be bought anywhere.
There is one more bearing in the case. The smallest one, on the input shaft. I couldn't get it out easily, it feels ok so I'm leaving it there.
