Here's my 1981 CB 750K: http://www.bikez.com/motorcycles/honda_cb_750_k_1981.php

Lists 77 HP stock.

Here's the 1978 CB 750K: http://www.bikez.com/motorcycles/honda_cb_750_k_1978.php

Lists 67 HP stock.

That's a 15% increase in horsepower.  That is fairly significant.

You also have to account for the the 81 being 564 pounds wet and the 78 551, but that is only a 2% increase in weight.

Of course, modding will get you a lot more and it's all about how much money you want to spend.  If you really want to go fast get a ZX14 with 192 HP
