Last night my brother and I did the throttle stop mod and the grey wire mod on my 05 WR450F. I also punched some holes in the closed side of the air filter. After we got it all put back together and started it up it idled fine and rev'd up fine, but after reving it up it would idle really high then slowly come down to normal idle. Not sure what the rpms are but I would geuss if it idled at 1k it would hold between 2 - 3k rpms before gettting back to normal idle. We also put in a 170 main jet to help richen it up since we ride at sea level most of the time. The exhaust pipe was glowing orange within 1 minute of startup, does this mean it is idling lean and if so what is the jet that I need to replace to make it richer at idle? I am going to order the JD jet kit when my next paycheck rolls around, will this kit have all the jets required for this? Thank you in advance for your help.
