Hey dudes. I just picked up a 2007 WR450 here in CO Springs. Got a screaming deal on a 'used' bike from an old timer, I use the word "used" lightly because the bike had 62 miles on it when I bought it from him. He bought it new and it sat in his garage until he decided to get rid of it. Needless to say it's brand new. That said, I did a few of the free mods i.e. grey wire snip and tuck, snorkel removal, and going to remove the AIS so I can tune the carb properly. I also want to disconnect or fix the TPS so its not twitchy on the road.
I already jetted the carb to the altitude here in CO Springs and got it pretty good but not optimal. Still have the dreaded "bog". Along with the temperature dropping from 65 to 40 in the past four days I am gonna re-attack the jets for winter time. I'm running a JD Jetting kit and GYTR fuel screw, I cant remember what jets I put in cause that was two weeks ago and I can barely remember what I ate for breakfast. I am waiting for new leak jets in the mail so when I get them I am gonna yank this carb back off and get her good for winter.
I also wired a brake switch and Baja Designs brake light fender license plate thing. Installed Avon Distanzia tires as I'll be using the bike for commuting this winter, about 70/30 road and trail respectively. Getting the state patrol inspection for an on-road title next week.
Ive not met anyone around here that rides trails yet so I am hoping there's some Colorado locals who can offer some help with jetting...
I'm running an FMF power bomb and Q4 exhaust and a UNI filter so I know that effects jetting... Also I am not an extremely aggressive rider but would like a little more pop from my throttle in the low end for getting up and over stuff on the trails. Already bogged it a few times trying to get outta holes and over rocks on the trails.
1. Anyone have suggestions for jetting for this area? What is everyone running for jets in summer and winter Colorado Springs area?
To wrap this up, thanks in advance for the help and the forum has already provided a lot of info for me getting the WR running good thus far. If anyone wants to ride hit me up.
