Unfortunately i could not find any techanical detail on road prince website nor has the manual anything saying about the bore stroke and compression ratios. But the head is 107cm. Another thing is that when i look at the carburettor, it seems exactly same like that of installed on 70cc. So how come a 70 carb is powering a 110 cc bike?
Another thing funny was that the label installed on the chain cover showing how much air pressure should be in tyre is also of 70.
I am attaching the pics for your reference.
Brother you asked for engine close up pics, these are for you as well
