New WR426 Owner!

This is a great site stuffed full of great info!
Anyways, I am currently setting up the WR to my preferences. So far, the dealer removed the exhaust plug and put in a YZ throttle stop. All stock otherwise. Only have about an hour on it so far, but it IS different than the YZ! It snowed here last night 7+ inches, so now I gotta wait until it warms a tad. Any other freebies I should do before breakin?

I do not have enough time on the WR yet to get into changing the power curve. The WR tranny really spreads things out compared to the YZ close-ratio. I have to get out and put some miles on the WR to get a better feel for it.
Thanks for the info!

The grey wire mod won't give you YZ mapping, but it will improve performance, with or without YZ cam timing. There is no grey wire on Canadian models...It only serves to retard ignition timing to reduce exhaust emissions on USA's WR's. To have YZ ignition timing, you could install your YZ's ignition control module on your YZ-cam-timed WR... This would also raise your rev-limiter from 10500 RPM to 11500 RPM.
Removing the grey wire does switch a WR CDI from the WR ingition timings to the YZ ignition timings. It also makes a difference in the upper revs. I wish I could find the link for it, but somebody did a complete writeup on the grey wire mod with charts to show the spark advance versus speed with and without the grey wire connected.
