Need info on tire size

Quick Question?

I have heard that if you go up in tire size in the rear for a 400, from 20 to a 22, you will lose torque but gain top end. How much? Is it going to be a noticable difference. I mainly do trail riding, so I want the extra ground clearance but I don't want to loss to much torque. I can't see that it would make that much difference but wanted to see what you guys have to say.

Well if you dont want to lose torque then get a 14t front sprocket. With that you can use 22 inch tires and it will work about the same as a 15t front sprocket and 20 inch tires (stock setup)

Changing a sprocket, won't void the warranty, right? What if I stay with the stock sprocket, will it be a noticable difference? How much top end will I gain. Thanks for your help.
