Hi, here goes my first thread as well as my first post on here! Name is Matt. Been a reader for quite a while and have learned a ton from these forums. Anyways, i'm 24, and have liked motocross bikes since I was 6, my uncle was an mx rider here in the northeastern ohio and shoot mainly all over ohio (greg urban, 803, rode hondas say something if you know him lol) but ever since I was a young gun i was in love with bikes but never had one of my own, just a 90cc dinli 2 stroke quad my gramps got me in mansfield on the farm when i was about 12, lol! That thing and that farm are long gone, they didnt pay taxes and ended up gettin screwed for it, lost everything, all the toys, boats, quads, golf carts, had to sell it and move to somewhere much more affordable. My family isnt the smartest but theyre pretty cool. ANYWAYS. I am 24 now and just recently had the chance to grab a bike to work on, ive spent my live doing other things like skateboarding, going to school, working full time, moving in with a girl etc. So I just found a 1990 yz125 on offerup for 200 bucks. I was dead broke at the time paying court costs n whatnot but I pulled together 100 bucks and made a deal with the guy to pay him 50 a week for the rest, since I had practically nothing and had literally just started a new job. So he was down and we met up and I got the bike. (QUESTION: Can i post any sort of htm image codes so I can post these pics throughought the thread? Cause if so im gonna edit the heck out of this thread and make it way more organized.) I brought her home. The reason it was so cheap is because the crankshaft was seized. The piston is in good condition, the cyclinder as well, no scratching or chipping, leading me to believe the issue could be in the main crank bearing. The guy I bought it off of has been in close contact, i see him once a week or so and we talk bikes and about the parts i'll need and whatnot. So my next step is to grab my next paycheck, finish paying him and bring the engine back over, split it open with him, and see if its just the bearing or whole crank assembly. Either way, pretty stoked about the deal, and the piston and cylinder being in such great shape. Im gonna attatch the pics of the bike and the engine! The cylinder head is taken off as well as the pipe and kickstart but here she is. Any input is appreciated! This is my FIRST bike and if anyone has any pointers about working on 2 strokes this old, I would REALLY appreciate it! Thanks yall Also if anyone notices anything that I am not saying, please do say something! Or if there is anything super critical to check. I plan om getting a manual when I find one and literally checking every single thing that can be loosened and tightened on it. Matt
