    New Seized-Crank '90 Yz125 Project Bike (Noob, Need Advice)

    UPDATE: I was about an hour away from ordering a new crank setup for it. Then my grampa calls me saying dont order anything yet let me open the case and make sure of whats going on with it. Ill be there within the hour to get it. I said sure it cant hurt. So i gave the engine to my grandpa who is an expert on anything with a motor and he and his brother are going to split the case tomorrow and try to diagnose it. My uncle used to fix Triumphs and shit and my grandpa retired from GM so before i go ordering parts theyre going to try to unfreeze the thing. They told me they looked at it briefly today and see a lot of rust on everything, and think it was ran without oil. There is hardly any play on the con rod, hardly any at all. They are afraid due to the rust and the lack of play and how OK everything looks that it couldve ran without oil and everything just swoll up and froze. Tomorrow they will be opening up the cases and checking all the bearings and what not as well as closely inspecting all the parts of the crank. Best case scenario, he calls me saying they got it to turn over and it was rusted out or jammed up real good. Second best, they say yeah your crank bearings shot its gonna need rebuilt or need a new one. Third/worst, they tell me the thing is rusted out from the inside or completely jacked from running without oil and everything is sort of destroyed. One last note, there is some mild chipping around the edges of the top of the piston, i thought that could be due to the rod bearing failing resulting in enough vertical play for my piston to smack the cylinder head. They said noo it doesnt have near enough play for that. Theres also a bit of light vertical scoring in the cylinder, just enough to be able to see it when you shine a light directly into it. I am stumped about this. I took it to a shop and they shined a light into it through the top and said yeah we gotta rebuild this crank, $450 dollars please, so i said hmm that was sort of a quick diagnosis without taking the case apart so i took it home and thought long and hard about what to do next. I am afraid they just wanted money because of how quick they diagnosed it and they probably thought i was naive and inexperienced enough to just throw money at them. But now i am considering that they were correct as well (however i could get it done much cheaper). I need some real tips on what to look for here guys. I guess we wont know until they take that case apart right? Im bummed because i was ready to just order a splitter, puller, and a whole new 87 crank and go to town but Im glad someone slowed me down. At least i hope, cause who knows if I had it right or not. Im going to give my gramp and uncle a couple days with it and if they dont figure it out i'll grab it back from them and go rent the tools from home depot and do it myself because i seem to have good luck getting to the bottom of mechanical problems and it seems like everyone else i trust just gives me anxiety about it lol. I feel the best doing things on my own and always seem to make it work. So right now im in limbo, because I havent had the tools to open it up myself and im just waiting for a call back from my grandpa and uncle to see what they find. Edit: the counterweights dont look that rusty to me, just the rod, flywheel, sprocket etc. I bet this thing just got some water in it after whichever dummy before my tried to check it out and gave up. Probably left it out and got wet. Thats wishful thinking i know. We will see.
  4. Hey all, I have been waiting for this day for quite a while. I am finally able to fix my bike, i've been in debt for some time but the day has come Now i have a question, when I got my bike checked out at the shop, i was told i could rebuild my crank with any rod and bearings from 1986-2000. I am going to purchase an entire new hot rods crank instead. Am i able to order any crank from 1986-2000 for my bike? Mine is a 1987. I just want to make sure I am getting the correct part before I spend the money! Appreciate any replies or help. Thanks!!

    What's up y'all, been real busy lately, but I'm out in the garage working on the bike with a space heater now. I'm trying to take the engine off so I can crack it open, I got the clutch unhooked and I'm currently working on the stator/ flywheel, is it absolutely imperative to remove the stator or and flywheel to get my engine off? Only asking because I don't have a flywheel puller and this might be a little bump in the road, any way around this?

    Looked up serial on the piston, its a wiseco 58mm. Heard good and bad about wiseco pistons. Ive heard they make good parts but its a hit or miss with the pistons...any insight? Also it being a 58mm, and me being a learner still, got a little question. is 58mm the stock size piston for a 125cc? I recognize the sketchiness of this old thing LOL I plan on replacing it.

    Got it, is it okay to try the wack/taps with the piston still attached? And cleaning the inside of the case, should i do it the same as I did the other parts? And believe me, if I get it running without a rebuild, the rebuild will be coming soon after, soon enough I'll be more financially stable and able to give her everything she needs!

    Gotcha! Got a bike shop by my house im going to ring. Just took a video and some pics, its still mounted and the engines not split so its kinda hard to see anything, but this kind of made me realize i really need to get this engine off and really look at it closer. Let me know if you see anything. Probably going to try to find a whole new crank setup on ebay unless the bike shop has some good news for me. Rod has a tiny bit of play to the left and right. No vertical. Piston obviously isnt great but not quite ruined either as far as i can tell. Ill throw these crappy pics in for now while the video is uploading. It was pretty damn hard to see so im gonna end up dismantling it im sure.

    Thats what i needed, a picture. Ill check it out when I get home maybe a take a pic of it for yall. If one of those washers is effed up, im looking at atleast replacing that side of the crank youre saying? Not too much of a shock considering i planned on doing the whole thing if necessary. So if that washers jacked, probably looking at a rebuilt or new crank, but if I find out its just the bearing, can I just replace that? Pretty damn sure my rod is fine too btw. Gonna get some more in depth pics later

    Might have to try the original a few times fore i pop a new one in. Might be a chance willing to take. First bike, behind financially, tons of excitement, you know how it goes lol. Will definitely look up the number on it and see what i got next time im working on it. Thanks man. Ahh i see, used to use a hand tool like that on a power drill at the shop. Will def look into this. Great advice, lots of good info, will remember these products!! Will keep you all posted. Appreciate the input everyone!! Wont be long. Not too much to do on her as far as i can tell but im ready for anything!

    Will do!! Measure the bore diameter with calipers right? Never heard of using sand paper or "quick ball hone" but i am familiar with machining just havent heard of that, will check it out!!! Is it difficult to get it perfect all the way through doing it that way?

    I would love to have all new internals before trying to fire it up so that is a goal....might regret not having it pristine inside being 30 years old

    Well I thank you for that, this is something I absolutely needed to know, the guy must have had no idea himself, selling it as a 1990. I always noticed when I googled 1990 yz125 the forks looked different than mine. Yes, I have read everything and you guys have just saved me a lot of time and money. I will be keeping you all posted as I go so you will know the parts I'm ordering and when! Also, I may end up opening it myself, but i'm not in a huge hurry so i'm trying to have someone experienced here with me. But I will be posting all about it and asking a million questions if I decide to open it and check it out myself. Thank you all so much, all of the advice and kindness is overhwhelming, this is a great community!!
