WR450 Grey Wire Dyno Charts
Posted April 10, 2006 - 12:53 PM
I have read through the free-mods, and like the idea of hooking up the grey wire to a handlebar mounted switch so that I can switch between full power and reduced power depending on riding conditions, etc. It would be nice to see a before and after dyno run of just the grey wire mod with no other mods.

You'll want the WR450.
It is more powerful than a 250 but with good throttle control you can do the same.
Claimed dry weight of only around 15 lb more and tons of power. The way these things can 'lug' hills is unbelievable.
If you still want less power than a 450 leave the pipe plugged up and just do tother free mods and jetting.

That might be what I was thinking of.
I found the ignition timing dyno charts by McGrath, but couldn't find a HP/Torque graph...could you be more specific?

I'm still a rookie on bikes, but can ride well enough to have fun on any bike as long as the terrain isn't too technical. I have a CRF450 now, and it is way more power than I need, and in fact, almost hurt myself pretty bad last fall because I let the power get away from me once, and let me tell you, it can happen in the blink of an eye!
Anyway, knowing my own abilities and the types of riding that I do, I think I would outgrow a 250 pretty fast, which is why I am leaning toward the 450. Perhaps a WR450 bone-stock, out of the crate would be a perfect bike for me to get my big-bore-thumper legs under me and learn better throttle control, then start doing the free mods as I grow into the bike...?

For a very long time it was not even there on non-US models. I think it's on Canadian models now.
Everyone who has gone to the trouble of putting it on a switch says that they never turn it "on" (connected). Yes, the bike has to be shut down and restarted every time the status of the wire changes.
