Hey I'm in desperate need for a bottom end for this bike. The compatible years are 88 to 92. Anyone have any laying around?
1989 yz 125 bottom end
- Thread starter gladeslife
- Start date
I guess I'm going to have to attempt it. What are the special tools I need? Is there any I can't get away with not using?Cheaper to rebuild....
Buying a used bottom end will put you right back where you started, on a gamble.

Flywheel puller

One special tool and alot of patience to split the cases. Sometimes they come apart easier than other times.

If you got the money, you can pick these up. They will help a lot but not needed. I don't have any of them and got away with a complete rebuild. Like BIG D says just use patience and some ingenuity.

Thank you guys for posting those links. So I'm taking the flywheel puller is the only thing i definitely need? I need to get a manual and video tape the disassembly so I don't forget.
Ok. Some one told me I have to have a machine shop do the crank. Can I do it on my own if I follow the book or should I let the pros do this part
I would let the pros do the crank. They have a special Jig that holds the crank halves in perfect alignment during the pressing process. -BIG DAN
I wouldn't. If you don't get the crank back together exact it will be off balance and rattle you to death before it finally destroys it self. Plus you have a serious press to do this.
Can buy a whole new crank also, check pricing, might be just over a rebuild.
None available for this particular model. None of the big 4 manufacturer's are cranking them out....

That's why I'm thinking of buying this bottom end on eBay http://bit.ly/1fhxBh8 I can't even find a crank on eBay so for 300 bucks I can be back in the game because I already have a new top end.None available for this particular model. None of the big 4 manufacturer's are cranking them out....
