Consider a '99 Warrior with Uni Fiter, re-jetted carb, White bros Pro Meg Pipe and 20" rear tires. Will it still hill climb with out bogging out with the 15T front???? We climb lots of hills and I'm undesided on 14T or 15T. They say 14T is close to stock gearing with 20" rear tires so if thats the case I'm not interested.

Do you have to modify your bike in any way to run the 15T front????

 

I ran a 15T on my Warrior almost the entire time I had it. It bolts right up and used the stock chain length as I recall. A16 tooth is also listed as fitting the Warrior, but I don't see how it could fit without alterations.
I rode the quad mostly in XC and 50"desert trail in cool weather +woods in Summer and still had all the low end I needed. You're right about the 14T with 20" tires...I tried that first and it felt pretty much the same as the stock gearing with 22" tires.

 

My 15 with 20s feels about perfect to me.

 

15T it is then.... Thanks guys...
