Chains don't stretch (at least not with V-strom horsepower). They wear inside the rollers, so that's where they get longer. If yours gained 2", that's really a lot of wear, and you're lucky it didn't break.
The chain is wearing and ready for replacement when you see sticky links, or can pull the chain away from the rear sprocket, or you see rust coming out under the rollers.
Wilson, you did replace both front & rear sprockets, right? They wear as well. At 33k, they're overdue. A new chain on worn sprockets won't have a long life.
