YTM 125 engine rebuild help

[jakep53]

I ended up tearing my YTM 125 motor apart turns out half the bottom of the piston was gone and the con rod has no bearing left at all!! so I tore it apart and split the cases I have never done this before and I did it without a manual, so i'm going to rebuild it every bearing and seal, but im having trouble finding seal kit bearing kit and what i need to rebuild the crank if anyone could help me out it would be much appreciated!
thanks

I ended up getting bearings and seals from a local bearing store. Purchased a complete gasket kit off e-bay. Not sure if I can post the link, but here it is ..

While waiting for parts, I cleaned all the crap off engine .....

My crank was good , with the exception of a slight bend in the end, on the flywheel side. But I have access to a machine shop and straightened it out.

You can get yourself a manual online at http://www.oscarmayer.net/atc/manuals/

Good Luck

Thanks for your help appreciate it! looks like them I will buy them in town, I always use that site but there is no manual for a 125 on there tho? or are you using the 175 manual?

Yes. The engins are essentially the same for the 125 and 175 with a few differences. I just compared parts at this site...

The lower half of my engine is a 125 and the topend is from a 175. I also have carb, fuel pump and exhaust from 175.

I am close to having everything back together so I can fire it up.
