Probably need a little more information here! I'm going to assume that you mean with the bike in nuetral and engine at idle, the rpm's drop when you engage the brake. This is probably due to the electrical load from the brake lights causing the alternator to kick in. If it is happening everytime, might indicate a weak battery.

Hugger, your right on all except for the battery and alternator are new. I'M like you, I think it is the stop light circuit. I'm going to pull bulbs to see what happens. Thanks

If the RPM only drops slightly when you apply the brakes, it is due to the current draw of the brake lights and is pretty much normal when you have a stock alternator.

I had the same issue. Alternator was fine. I replaced the brake light bulbs with Cree LED "bulbs" and no more rpm drop. LEDs are available everywhere, I got mine from Amazon. Got the 1157 red.
