it proably would only pick up a couple a mph. but u would see a major increase in low end and midrange power. it would only pick up a couple a mph becuz ur not able to change th gearing on the quad.

yea that sucks that you cant change the gearing...it would leave a world of options for added hp

from what i understand it would add a few, maybe 3-5 hp maybe more but it would dramatically increase low and mid torque.....thats my understanding

When it is stock it is from low to mid 50's or atleats in the atvconnection they had 53MPH for top speed so it will probably go about 57-58 or something around there.
