Project
Hello guys,I have a technical question about my project,so I search for the right place to ask and find this forum.First of all I have to apologize to you guys for my bad english I will try to explain as much as I can so you will be able to understand me.
So my question is about my engine head,
I'm planning to raise the cc of my city bike so I've decide to upgrade,I'll upgrade the cylinder from 52.5mm to 56 next I'll upgrade the head valves from 21/23mm to 24/28 mm.
Next I'll get 28mm carburator with 28mm manifold.my main question is,I'm thinking to make some modifications of the head entrance I mean the entrance of the fuel/air mixture,so I'm thinking from the start of the entrance to make it 28mm and as it goes further in to the head to make it smaller to like 26mm or maybe 24 my goal is to make it like a funnel,so my question is does this will work or will not be a good idea to do it,I'm thinking that if I do that I'll increase the fuel pressure before reaching the valve and will increase the speed of the fuel also will increase the suction effect.im not a engineer or something I'm just thinking and that's why I'm searching for help from you guys.So what do you think is this a good idea to do and will this helps me in some way or it will make it worse.
