Ah...I'm an idiot.. i totally though my bike was a H1, but its an F model.
anyways, I want to take the air box out. Though I've been told that if i do that,
I'd have to upgrade the jets to keep from burning out the valves. Is it really necessary
to buy a jet kit, or can the carbs just be tuned richer to compesate? They need to be tuned
anyways. i also want to remove the emissions control, its a CA model. Two hoses connect from the seperator
to the top of two carbs.. Vaccum i assume, can i just pug these?

here's a link to look at some diagrams if you want to

If you run with no airbox you will need to rejet. Why no air box are you turning here into a drag bike?

Your link was no good and wants us to log on. Cut and past digram into your post.

 

Yup, you will have to rejet. Any change to the intake or exhaust will require you to rejet.
