450R Exhaust

[matt8303]

Hey guys I was wondering if I would have to change the jets if i put on an aftermarket exhaust with the HRC kit installed? Also where can i find the woody sticker kits? Thanks alot.

yes you will need to rejet, but id be interested to see what jetting is bieng run with the hrc kit installed, then adding the pipe.

hmf offers jets with thier full systems btw:p

Mine is bone stock, stock jetting, with a GT Thunder full system and runs perfect!

Rowl you run airbox lid on or off?

The jetting on the HRC kit is a 185 main and a new needle. I just bought a full system from HMF and they said I only need to change the main jet to a 190.

Thanks guys. so would I be running lean or rich? kind of new to the mechanics side of ATVing.

You would be running lean. Look to see what color you plug is. It should be light grey or light brown, NOT white.
