I just purchased a "Power Now" carb adopter devise that is suppose to add more throttle response and eliminate the need for using the "hot" start button. I was a little skeptical at first, but it does work. For me, this is worth the $70, as I frequently forget to turn the hot button off once the bike has started. Another item that I have found that has helped me ride my beastly WR426 is a Malcolm Smith clutch level with the multiple cable pull slots. I have used the easiest cable pull setting and have eliminated a great deal of arm pump and bike stalls.
