The mini yamaha

[Ratranger]

So despite the norda being ongoing, I picked up another project. A 1987 ysr50, it's currently ugly, and will be getting a few upgrades. Biggest is a zongshen 250cc counterbalanced 6 speed, next will be grom wheels with a brake upgrade. Debating grom or z125 forks with a better rear shock.

I'll follow...

Your work is great; so I’m in too.

 

[Ratranger]

Thanks, it should be a fun bike when it's done. They're kind of the OG grom. I think I want to go full 80s and finish it with the lucky strike livery.

 

[Ratranger]

It's gonna be a tight fit. I think I'll need to shave the cooling fins on the right side of the head.

Rear upper mount is in place, I need to figure out the rear lower mount next. Then I can put the cradle on and do front mounts.

 

[Ratranger]

Sprockets line up. I had to make a new cush hub for the grom wheel to fit and line up.

 

[Ratranger]

I got the front mount mocked up. Now for cleanup and welding. It should be plenty strong and help with stiffening the chassis.

 

[Ratranger]

Those mounts aren't going anywhere.

 

[Ratranger]

I had to check, plenty of room for a carb under the tank.

 

[Ratranger]

New intake in the works. It'll get the carb pretty level and give more room for a filter.

 

[Ratranger]

Carb fits pretty nice. It'll clear everything with no interference for the cable either.

 

[Ratranger]

Triple clamps for the grom forks are getting close to finish work. Next will be the steering stem.

 

[Ratranger]

I'm working on the slow process of making the steering stem. The atlas lathe isn't fast, but it can be accurate.

 

[Ratranger]

Just about finished with the steering stem.

 

[Ratranger]

Definitely going to need the racing bros lowering tube kit for the grom forks. I knew I probably would, and I bought these forks mainly for the lower lugs. You either need a stock set or aftermarket. The stock dirty but straight forks were under $200, aftermarket lowers are over $500.

Well the off the shelf caliper brackets on amazon are indeed garbage. They don't clear the rotor mount bolts for 1, and 2 they are for full size radial calipers. So with a little cutting, a few tapped holes and some aluminum angle I had, I can now get the measurements to make my own bracket for the bybre caliper.
