I have a 98 warrior.

I need to redo my chains and sprockets so i want to find out the best combo. I have a 11.5 to 1 piston and a f&m pipe. I would like to know what size jets I need and what type of gearing I need for 22 inch mud tires....... I have dropped 4 teeth in the back but feel that is way too much. Should I go the other way from stock? I run 25 inch tires now but I want to get a set of 22 inch bear claws.

Any ideas?? please help!!
