HRC Rejet for HMF Slip on

[450retzer]

Hi, I have a 2005 Honda TRX450R with a factory installed HRC kit.
The exhaust is the stock can with a different end cap.
The HRC kit changed the main jet size to a 185.
It has the HRC camshaft and the airbox lid is now the HRC style.
I plan on buying a HMF slip on exhaust for it but I only have one question.
Will I have to rejet my carburetor if it is already re jetted to 185?
If so, what size main jet would I have to install with the HMF slip on?
The way I understand it is that if I dont rejet the carburetor, the bike will be running rich.


Thanks, Tylan

Tylan, the 185 might be a hair rich. Air filter/backfire screen will also play a big role in determining this. 180 is what we found to work best with on the 04-05 TRX450 with our exhaust no lid and a free flowing filter with no back fire screen.
