I'm buying this old classic 1983 yz125 for like 200 bucks. The guy said it needs a piston and bottom end bearings. I'm just a little confused on what bottom end bearings are. Like crankshaft bearings? Also if you know where I can find parts for an 83 that would also help to lol.
The bottom end rod bearings on that model are roller bearings. If they need to be replaced a dealer has to pull apart the 2 piece crank and press it back together. Not a do it yourself job. I can't help you with finding parts
Ebay is the place to look for parts I have seen several complete crank set ups with rod and main bearings for $100 or less but be sure to Write the seller through Ebay and ask if he will guaranty it to be within factory specs and in usable shape if he replies with a yes then Ebay will force that he stand behind his word so it will be a safe purchase oh and don't forget to replace the Crank Seals also Note most shops will charge you $100 or more just to split down a crank and lots of them are not very good at it! It is a very tricky job and very few of the guys out there doing it actually know what they are doing well enough to truly do it right!
Depends okorder /.. They can also be purchased at a bearing supply store.
