Just bought an '06 WR450F and started looking into the free mods talked about here on TT. I have some questions hopefully you all can answer. I've been riding it for a couple weekends here in FL in preperation for a big ride in WV in 2 weeks. I want to open it up before a go but don't want to screw anything up before the "big ride" or spend much time tweeking. I have 1 weekend left to get ready. With that in mind what would you do to the bike?
Also, any help on these would be appreciated:
1. Which mod gives you the best performance improvement?
2. Can you do these mods independently of each other, or are there some that need to be done in conjunction with another? (ie; can I do the throttle stop cut-back and roll?)
3. I understand that the AIS kit stops the popping noise, but does it improve performance? I read somewhere here that it really doesn't? What needs to be done in conjuction with the removal?
4. When cruising along in a high gear and low RPM's, there is a knocking noise made when the throttle is laid on. Downshifting and getting the RPM's back up stops the noise. Is that normal?
Agian, I have 1 weekend left before my big ride and just want to get the most out of the bike.

call thumper talk, order a pro moto inster (pmb) about 65 bucks.
this will take the pie shoot out of the stock exhaust. it will still keep the bike quite but will also give you some more power.
while you are at it also buy the TT AIS removal kit. its better than the yamaha one. its also about 70 bucks. it takes about 40 mins to install.
your will need to also buy a JD jetting kit so you can rejet your bike so it runs right in the area you ride in. its also 70 bucks but worth it.
pick a zip tie fuel screw too. make sure you get the right one. ask when you call.
Depending on what jetting specs are recommened in the Jetting guide, you might need to pick up some more jets. there are a couple good websites that you order these from.
you might as well do all of them at once, if you leave the smog pump on, you will have a hard time jetting your bike. your bike is already lean so if you run it hard (throttle stop cut) you run the risk of damaging the motor.
you have no idea how this is going to change the bike. take the time, spend the money and get your bike running right so you can have good time your up coming ride.
oh and when your in high gear going slow that noise is normal!
also try using the search button it works wonders.

Took me about about 3 hours to do the work:
- pro moto insert
- airbox snorkel
- smog removal
- throttle stop
- jd jetting
The bike runs perfect and actually starts now without the choke!! Thank you all so much!!
