Get the competition kit (programmable ecu and throttle stop screw) sold together for $100. drill out the oem muffler restrictor (pea shooter), and get the mapping reset (by dealer) to FMF map. You can fit a bigger muffler tip on the oem muffler (same one that fits older WR's), and you'll be set. I can rent my FI tool to you for resetting the CO level to make it run even cooler. PM me when the deal is done.
03 WR vs '12 WR450...

Really enjoying all the discussion regarding this subject guys... Based on what I'm reading and the fact that I'm not interested in putting a top end or any more money into my 03 at this time- I am definitely going to grab a '12 from my local dealer this next week. I'm doing some research with the search function now- but if anyone can recommend what mods (engine/exhaust wise) that need to be done to open it up like my 03 is. Don't want to touch internals (cams) but remember reading bout a GYTR ecu, throttle stop and taking some plug out of the stock exhaust... What if anything else do I need to get from the yami dealer before I leave? Hoping to work some of it into the deal... Appreciate everyone's thoughts!
You should get your dealer to set the CO level, which requires a different 'tool' than the GYTR tuner. If they can't or won't there is one for rent for forum members.

Sorry- new to the fuel injection stuff... What is the CO level? If this something most dealers should be familiar with? Or am I going to have to walk them thru it to get it right?
Depends on the dealer. Now that the bike has been out a couple of years, some dealers have been through it and know the drill. I had to explain it to my dealer the first time, they thought I wanted a different FI map with the GYTR tool.

CO level is simply the idle carbon monoxide readings. It indicates the relative rich/lean state of the engine's idle base line. Most of them are a bit lean for emissions reasons. The GYT-R tuner is not capable of resetting this parameter.
