Do a google search for motorcycle gearing calculator, or similar. I have a bookmark for a great one I'll have to look later when I get to my computer. That will tell you the rpm change. Keep in mind your chain length may change, also wear profile too. Generally for every 3 teeth on the rear = 1 tooth on the front so if you want major changes use front for bulk and rear for fine tuning. Avoid having both sprockets with even numbers as that will wear the chain quickly because the same tooth will wear the same link instead of migrating across the whole chain.
