2007 WR450 Help!!!
Posted November 20, 2006 - 09:54 AM
New to the site....I am impressed by the amount of useable knowledge the members of this site display, thank you.....
Does anyone know if the 2007 WR450 is going to require the same mods as the 05 and 06? I take delivery of an 07 sometime during the next week and I just wanted to see if anyone had the tech tips sorted out yet....I currently ride a YZ125 so this change to the WR should require a rag in my riding kit to wipe the s$&*eating grin off my face.

just picked up my o7 wr today the dealer gave me a ais removel kit from last years bike does anyone know if they are the same and will work on the 07
New model = a whole new set of issues. You're one of the firsts, so you may have to venture into uncharted waters and find out all by your lonesome. Aftermarket products and homegrown tweaks are going to be a ways off. It's like deja-vu all over again...SC

the pilot jet and needle and Yz throttle stop are the same but the AIS block of plugs are not the same size. From what I read everyone is making their own block of stoppers.

I followed the included directions re: pipe mod, airbox mod, disconnecting grey wire, jetting, throttle stop, and removal of AIS system. Both bikes run very good now & a lot cooler.
We have had issues with coolant & fuel tank boiling in very hot, slow conditions in the Los Padres NF & Redrock Canyon desert areas. I replaced the coolant with Evans NPG+ coolant & taped the bottom & front of the tanks with heat reflective tape. This has eliminated any problems with boiling coolant or fuel.
We just returned from a trip to Nevada with some riding on the way in the Sierra's at over 11,000 ft MSL. The bikes were slightly rich but ran OK at all altitudes.
The only issue I am having right now is that my WR kind of surges/misses at low throttle settings when running along a section that doesn't require a lot of power. Both our bikes are identical & my son's doesn't do this at all.
I have read on TT that it may be caused by the throttle position sensor adjustment on the carb. I checked the voltage/resistance settings according the manual & they are within the recommended limits.
The carb is a MAJOR PITA to remove so I have been living with the surging. It is worse at higher altitudes.
Overall, we love these bikes. Great handling, power, & suspension. The only other thing we did was back the compression damping off a couple of clicks on forks & rear shock.
Also, make a SS shield for the subframe to avoid the chain eating through it. Running the chain tension at minimums & aligning it carefully reduces the chain rubbing.
Just my $.02.
