I did the throttle stop, air box & baffle modifications on my 00 WR, as described in this forum and my bike has more power and revs quicker(thanks for the posts everybody).

I rode it this weekend and when I would stop hard and start from a stand still as soon as I touch the throttle the engine will stall.

The jetting is still stock, I also noticed that now it would start a lot easier, in most cases in the first kick.

My next mod is YZ timing but I would like to solve this problem first.

It's time to learn how to jet your bike. With the changes you made, you'll probably need to richen things up. Do a search on the subject using your bikes year during the search. You may also want to search using Clark Masons or James Deans names for the search criteria...they are the experts on jetting.

Write down where all your settings are now, take baby steps (few and small changes), write down your changes and effects of the change and good luck.
