I'm entering my first race in a couple of weeks, Cherry Creek Desert Scramble in Young AZ. Ok my 99wr400 has a white bros e series with all the plates installed. It's loud, the way I like it. Sorry to all you quiet folks but remember here in AZ there is so much good riding with no one around for miles and miles. Well for this race I need to to tone her down alittle to meet their 96 db requirement. My question is how many plates should I have in there do ya think and will my jetting be effected greatly enough by removing them that I will need to rejet. I guess my other question is what are the three most important thing to remeber being that this is my first every desert race. I plan on entering the 30+ Class C group. Don't even plan on being competetive but just want to get out and see what it's all about. Thanks in advance for the help.
