2004 Crf250r Jetting

Edited Date/Time 8/22/2012 7:48am
Hey All,
So I'm borrowing a buddys bike at the moment I've been fixing it up because he doesn't do any work on it at all.
Just put a new rear tyre on it, new oil and filters, grips etc just making it a bit nicer to ride.
The jetting seems a little off, bogs quite a bit.. i know there are jetting kits you can buy but does anyone know what to change it to for a crisper response?
It is stock settings at the moment and has one of the older model PC Ti-4 exhausts on it.

Anyways any help would be good, thanks

check out their jetting recommendations...its a great place to start

if it has a Ti-4 Full System it definatly needs to be re-jetted

you will also want to get a Quickshot Accelerator pump cover and an aftermarket Air adjustment screw( i would recommend Flex Jet by R&D). these are must haves for any FCR carb
