Ok so I know why you ask? Well around 2010 we traded a crf 70 for this. My son went from an 85 straight to a 250f and I just wanted him to experience the 125. We brought it home and started tearing it down. Replaced stem bearings greased all other bearings and also had the motor rebuilt. Basically went through it without spending a ton of money.

Well he put about 5 hrs on it and found the rims cracked so we parked it, Been sitting every since. I quit riding about the same time and would just watch him and go to work on Monday with no pain. Now he's in the Navy and I am missing it so I need to get my fix.

I'm old and slow so I wouldn't know the difference between this frame and a brand new one and just want to have fun, probably going to race vintage and not have to deal with young guys wanting that trophy at all cost. Now on to the 2nd tear down.

Here's how it started this time.




Absolutely hate the sunken horse look of this year.

I have no shop so in the house it goes.

A little help from no thumbs here


This isn't my bedroom it's my home office.



I think this is where I stopped the first night. All work was done at night after work. Much more to come.

Not sure what it is, doesn't seem stock because of the bars.

Anywho I'm sending the frame and hubs and some other stuff off to get cerakoated. Also having my suspension done with race tech at my local shop. I'm tearing the motor down again because when it was built something went wrong with the right case and they repaired it. So I want to check it out.

Engine torn down, as you can see they did some kind of repair not sure if it is jb weld or what.



They don't make cases for the 98 so I was looking on ebay and have seen them used before but none was available at this time. I decided with only 5 or so hours on this build that I would run it at least for another 5-10 hours. The case looked like it would hold up for that much time. It was a wiseco crank and a pro ex top end so I put it back together. I did order new rings and circlips.I was definitely worried about the wiseco crank but figured I'd get some time.

Always been a fan of the 125. They are the definition of fun for me.

Love the graphics, I'm deciding whether to do this gen CR or the same year YZ for the Pre Mod (20+ year old bike) in my harescramble series, I don't like beating my MX bike up in the woods now. He rode great for being off 3 years, Looks like nice dirt on that track.

The bike turned out great... Good Job..
I know a lot of people hated the Gen 1 Honda's but there are ways to make them handle better and take some of the vibration out of them. KX Guru Racing is working on a project Gen 1 CR250R with a CR500R Engine.
And remember, just because some magazine writers or pro riders didn't like them didn't mean that they weren't good for the average trail rider.
Thanks for posting your project.

Sandblaster, Thanks for stopping by. We haven't had any problems with handling or vibrations at this point. Appreciate the comments.

Thanks lcgorden711, He definitely put the suspension to the test. He is also about 10 lb's over what I had it set up for me, but he liked it. I won't be riding that hard because I have the fear of the Monday morning J.O.B

Haha yeah once I got out of college and got my first real job I realized what my dad had been talking about for years that he has to go to work on Monday so he has to be safe.
