I've got a set of bike carbs but don't know what size to bore the jets out to I would like to get a cam for it s well but can't find one any were can any one help or I my gone down the route of a transplant but I would
like to keep
it as a 1.4 or under

Using a set of bikecarbs and a cam might get you up to 100hp. Which isn't worth the effort if you ask me.
I'd +T it with a 13c/T25 or small T3 which will not cost you that much more if you are creative about which parts to use, but will help you gain a lot more.
A 1.7/1.8/2.0 8v or 16v or turbo would be a lot more interesting.
