Just dont' want to overheat it or fry the seal or anything. I held it on there for several seconds and gave it another try but still no luck

Heat the nut for 15-20 seconds, try to remove, if not heat it again. Nothing was smoking when i did mine, there is alot of metal there that would Take alot of heat to damage the seal. I use a small propane torch with a low flame and focus the heat on the nut. Keep trying it will work, had to do the same procedeure on my ZRX1200, kawi dont want them coming off by accident.

Just gave it another try... I got the surface temp of the nut to 175 degrees according to my infrared thermometer and still nothing! I've triple checked to make sure the washer is good and flat behind it. Things like this will drive a man insane

Got it! One more light hit of the trusty torch. Then I tried it with the breaker bar again and then the impact gun got it right off. nearly ended up with a nice hexagon shaped burn on the palm of my hand after picking it up 
Thanks for your help everyone!

New board member here... been around motorcycle a long time but this is my first dual sport! Really enjoying it so far 
I was going to install a 13t sprocket and can't for the life of me seem to get the original one off
I know that the lock washer must be flattened out first so I've done that. I tried a 3 foot breaker bar and that would not get it. Went and bought an electric 1/2" impact gun and it still wont' budge! I've had problems with front sprockets in the past but used to have a pneumatic impact gun and that always did the trick. These electric ones don't seem to have enough "oomph" Don't have it anymore though so I"m out of ideas

My first problem was getting the chain off. I saw a post on here that helped get it on and off. But for the life of me I couldn't break the nut. I just bought a torque wrench and 22mm to do the job too. I read the "unhelpful" service manual which got me nowhere.
