Whats the best spur and pinion teeth number for the losi xxx and a green machine 3 motor?

ummmm, if you have an older RCCA mag with a Bk pitch ad, they have a conversion chart, or trinity's web site may even have the chart, there web site is www.teamtrinity.com (http://www.teamtrinity.com) if you are running an indoor track, that means you are probably using around a 21-23 tooth pinion, and whatever gear you are using, drop 2 teeth, and also check out the spur for an 82, that seems to be the best for the buggy, for me at least
