Feasible to modify a Hero Honda CD100 to make it look like the CB100?

One idea is to source a modern CG125 engine which is apparently very common in China (fake clone or Honda licensed copy) but it could be unreliable and expensive to import.

BHPian Retroclassic recently shared this with other enthusiasts.

Hi this is my first post here although I've been reading for a while. I'm interested in classic lightweight mopeds and motorcycles. I've always loved the early 70's Honda CB100 as pictured below which to me is the quintessential modern commuter classic. The single cylinder version had a vertical 5 speed.

This wasn't ever sold in India, nor was its successor, the CG125 (still popular all around the world including Pakistan, China and SE Asia). India did receive the very popular Hero Honda CD100 with a somewhat similar look but cut down 4 speed engine, but it is no longer sold and there's no classic 100cc bike in India at the moment to my knowledge that I could use as a base.

So the project is to modify an a CD100 (round headlamp, instrument cluster etc) for the desired CB look. Thoughts?

However the horizontal 4 speed CD100 engine would look quite puny and won't give the swept exhaust look.

One idea is to source a modern CG125 engine which is apparently very common in China (fake clone or Honda licensed copy) but it could be unreliable and expensive to import. Barring this, is there any Indian 100-125cc Honda or HH engine on any current or old model that would be a good fit?

Ps. I'm sorry if I'm not allowed to ask here, but does anyone know of a good CD100 for sale in Punjab or nearby states?

Thanks for your input and advice!

Here's what GTO had to say in this matter:

Won't be worth the effort, IMHO. Even if you manage the looks, you'll either have the basic economy-oriented engine from the CD100, or a poor quality imported engine.

Instead, why not save the time, and spend the same money on iconic motorcycles already on sale in India. If you prefer retro, an RX100? RD350? Not too hard to find a decent one, or one in need of restoration.
