Upgrading jets in yzf426

Colvin426 · 02-06-2008, 04:23 AM

I have A 2000 YZF426 and I would like to upgrade my jets. I havn't looked in my clymer manual to see what the stock ones are but I would like some suggestions on what woould be a good upgrade. also, once I jet it is there anything that I need to do along with jetting it?

There is no real reason to just to upgrade jets. In fact, they don't sell an "upgraded" jet. The reason you rejet is because when you add a component like exhaust or air filter, your bikes fuel mixture changes and to get the most out of that component you need to rejet. Read this and it should help.

Hey, no problem. Was there any reason that you thought you needed to change jetting? Is the bike running weird?
