I am swithching from 22 in. dia. rear tires to 20 in. on my lt250r I like the final gearing the way it is. I am pretty sure I need a smaller rear sprocket with the smaller tires but I don't know how many teeth to drop. Any suggestions?

 

i would try 3 or 4 and go from their or add one to the front sprocket which is equal 3 or 4 on the rear and it's alot cheaper to figure out roughly where u want your gearing by using the front sprocket versus the rear
