It should be able to pull it with a good slip-on, if you want to go that far. I ran 22's on friday, because my stock tires weren't holding air, and it pulled them fine all the way through 5th gear.

drop a tooth on the front sprocket. 22's in a stock setup take a lot off the low end torque. By going down a tooth (or two) in the front, you'll put top speed back where it was with 20's and also bring the torque on the low end back in line.

Going up a tooth in the rear is not only more expensive, but you also don't see as big a change as you do with going down a tooth in the front.

One tooth down in the front is like adding 2-3 in the rear.
