First off my apologies for a long thread. I've had my '14 TRX450ER for about two years now and I'm bored with the quietness of the stock exhaust. As of now I haven't decided on which brand of slip-on I want and I'm unsure about jetting the carb. I have read on another forum that if only the exhaust pipe is changed nothing has to be done to the carb and I have also read that only the pilot jet has to be changed. So I thought I would try to get some answers here because I haven't ever worked on a FCR carb.. So honestly I'm just wanting it to sound better and not looking for any real performance gains. Everything on my 450r is bone stock and I don't plan to so any mods to the motor or air box,and I would like to utilize the stock air filter if possible because it isn't a race machine. So to say the least I would like to know the simplest way and best jets to use for the Honda TRX 450ER. Any help would greatly be appreciated!
