Re: Cb125 Head With Oversized Valves and Cylinder NEW

am interested. is this a single piece head or split head design?
 
Re: Cb125 Head With Oversized Valves and Cylinder NEW

This is the single piece head
Cylinder is the 124cc

There two go together and are great for a custom build
Since the cylinder is 124cc it's matched to te latter two piece head pistons not the early 122cc singles. Nothing else would be different

What ifs the bore on the cylinder? Is it still stock 125? I have a buddy who is asking.

Yes its the stock bore for a 124cc cb125

The single piece head bikes were the early ones and had a 122cc jug
the latter two piece heads had a 124cc jug

To be clear this is a single piece head and a 124cc jug

Re: Cb125 Head With Oversized Valves and Cylinder NEW

sorry, noob here doing a cb125 rebuild. I've got a 74 with the 122cc single piece head.

I can bolt this on as long as I get the 124cc piston to match?
 
Re: Cb125 Head With Oversized Valves and Cylinder NEW

Yes you can.
Or bore the new cylinder out a bit for a hot rod big bore motor
 
Re: Cb125 Head With Oversized Valves and Cylinder NEW

Don't know if I want to go that far. This seems like an easy way to get a shiny head and a little more oomph... plus I have a NOS 122cc piston to barter.
