Yeah, the rear is easy, takes 15 minutes start to finish, the front is a pain in the ***, the front sprocket requires a ton of things to be removed and pulled out to get it out.
For that reason I went with +3 on the rear, and used that as an excuse to get a gold chain so that I could have it +2 links from stock, in order to keep the stock wheelbase with the larger rear sprocket.
Whereas -1/+2 the sprocket sizes sorta cancel each other out and keeps the wheelbase largely the same. Chain costs more than a front sprocket, but it was an easier install and looks better.
