How does rejetting work?

[Anonymous]

There is more to it than just main jet size right? What else is involved?

The main jet, jet needle &, pilot jets may all have to be changed. The main jet only comes into effect at wide open throttle, the other jets work at different throttle settings, so when you adjust your air intakes, you have to adjust the fuel intakes at all throlltle openings, not just full-open.
That's my simplistic take on it. I'm sure you'll get a better technical explanation from others on the site!

It i not smart to rejet without changing other components involved in fuel mixture first.

So are kits for our bikes still sold or would it be a matter of collecting up the larger jet, needle, and air jet to make a kit?

BTW, the bike has a 4-1 installed by a previous owner without rejetting.

if thats all you have and are going to do then a stage 1 kit is all you need if you are adding pod filters then you will need a stage three kit
and yes you can still get the kits look around on ebay. just make sure of which type of carbs you have.
