Just be sure you have the bike in neutral & use the back brake to loosen the front sprocket nut (36mm). If you try to loosen it with the bike in gear, then it will put strain on the transmission. With the bike in neutral, torq it back on while holding the back brake.
On the rear sprocket, make sure you buy a new bolt kit. To remove the old bolts always turn the nut, NOT the bolts. Always use loctite & a torq wrench.
Your new chain will have a master link. Make sure it faces forward. Like a fish swimming up stream. If you've never put on a master link, then you may want help from somebody with experience. If you put it on wrong, then it will come off.
