There are 3 motor mount bolts.One is right by the header pipe,the other is on the bottom dead center of the motor(kinda hard to see.The last one which I am assuming you are talking about since it's the largest is the actual swingarm bolt.To remove this bolt take off the nut and use a rubber mallet to start to bang it out.Then you will need a drift punch or equivelant to get it to go further.Do not take it all the way out just enough to clear the motor boss,then when it clears remove the motor and push the swingarm bolt back in place to keep the swingarm from falling out and to keep it a roller till your done.I would take out the bottom one first then the one near the pipe leave in loosely and remove right when the swingarm bolt clears.Hope this helps.Good luck
