I changed my battery on a 2007 kawski ninja 636 and now i get no power to the bike. I meant no lights no dashboard no nothing. I have an alarm n when that gets hooked up it works just fine. I checked the fuses and reset the battery. I also checked the battery and it's at 100%

Depending on the type of alarm you have, it could be cutting power from the rest of your bike... .I know that on my CBR that if the alarm and battery are not hooked up in the right order then it will do just what you are saying. This is to keep a thief from just unhooking the battery/alarm etc and make off with your bike. Thats what I would check next since you have already checked the fuses. Also to keep in mind is that there is likely a main "in-line" fuse plus your fuse box to check.
