    2007 WR450 Q's .

    Mine came 13/50, and no spare jetting. I did get different jets in the AIS removal kit though.

    High compression question

    you should be running 91 octane stock. The Owners Service Manual recommends 95 octane unleaded fuel (page 1-24). You won't find that at the local pump. So it would make sense that if you go to 13:1 compression, you should run even higher octane then that. The results of not running higher octane would be the higher probability of detonation. The fuel igniting before the ignition fires. This results in two flame paths coliding with each other and thats what makes the awful noise, and can cause severe damage.

    Gym training for off-road riding

    Situps is the key. Very important. I do half a rep getting out of bed in the morning, and the other half going to bed that night. I feel great, and look great, and I'm 50 years old. In fact, I'm in the best shape of my life.

    My '07 450 is almost here!

    Thats funny. I got my WR home after riding my brother in laws YZ. I rode the WR up the street expecting the same as the YZ. I turned around and asked myself, why in the hell did I buy this gutless bike. Found Thumper Talk that night and learned what to do to ale this bikes lack of any power, and did them immediately. What a difference. Also have the FMF Q4 installed. And filled the hole in my air filter with RTV.

    Changing Gears

    If I have my hands full, I don't even think about the clutch. When up shifting, I just snap the throttle towards idle then back on to unload the tranny. When down shifting, I snap the throttle up to unload the other side of the gears in the tranny.
  7. Mine had the hole as well. I cleaned the cage real good and used carb cleaner down the hole. Then I passed the end of a shop towel down it to wipe it out good. Then I filled it with RTV. It ain't coming out.

    INFO: AIS KIT 2007 ??? Part Number

    In the meantime, disconnect the grey wire underneath the left number plate at the CDI, it is in a six wire connector. You could also change your muffler. FMF has the Q4 available now for the 07. Thats what I am running. derwud2 is running the Dubach and he is happy with that one to. The grey wire removal and the exhaust change will make for a completely different bike.

    I did not get a torque curve, however, if your way smarter then me and can do a little math, you could figure out the torque. To much effort for my old mind though.

    YZ cams

    I was told by a local dealer that you could advance the exhaust cam timing one tooth and then it would be the same as the YZ. Anyone know if that is true?

    Dyno numbers WR450F, anyone?

    Here is the dyno run for my bike, a 2007 WR450F with dirt tire. Run 002 in Blue is with the AIS kit installed, but no mod to muffler or airbox. Run 004 in Red is same as above except with FMF Q4 muffler installed. Run 007 in Green is same as Run 004 except Power Bomb Header installed.

    It was with the 170 and 48 that came with the 05 - 06 ais removal kit. Now again, I was told they were going to tune it on the dyno so I do not know if they changed that as well. I am hoping to get the dyno sheets and notes.

    Thats true. I forgot to mention I did not remove the baffle from my stock muffler. So a little less from the Q4. Good catch. However, the Q4 still had the spark arrester installed as well. Which I promptly removed. Don't tell anybody.

    Dyno numbers WR450F, anyone?

    Altitude and air temperature both make for air density. Denser air (cooler and lower altitudes) equates to more HP. So if your dyno is in higher and warmer air, your indicated HP will be lower. However, most dyno computers will not only give indicated HP and torque curve sheets, but also produce corrected HP and torque curve sheets. Most all corrected numbers are corrected to a sea level altitude and 59 degrees F. The differences in dyno's are mostly how the operator loads the dyno. How quick it loads up, and how hard they hit it. With that said, different dyno's will produce different results. But, they won't be so different that they can't be used for approximate comparisons. As the previous poster stated, they are great for initial tuning. You would still want to check your tuning in the real world.
