Hi I'm looking at getting a new WR450F, from a dealer, either this season or next. If I get it this season it will be really soon, and as its closing in I just have some specific questions and I would appreciate if people would be willing to help. I've done some reading and I have learned that the throttle stop on the WRs should be changed to a shotter one, similar to the YZs. I was thinking of doing this with the GYTR WR AIS Removal Kit (GYT-5TJ93-69-01). I've read some controversial informating on jetting the bike and soo on, I live on Prince Edward Island, Canada. It is quite humide here, if I changed the throttle stop would I have to re-jet the bike? If I change the throttle stop is there any other mods I should do so that the bike runs smoother when more throttle is used. If I remove the gray wire will the bike over-rev? Is it best to mod the pipe and how do I do so? Basically I want to be able to use the bike's power without limitation, however I do not necessarily need to be able to go all out with YZ 450's for the riding I do. I do like to open her up sometimes though. Thanks for your help in advance, and sorry for being naive. I'm currently running a TT-R 230 and thats just not enough for me.
