I was wondering what to expect from the gear change and would like to know if anyone has tried or is using the 40 tooth sprocket.I really want to know if the top end will be effected by this change or will this gear change really wake this bike up.I'm just curious and would like to heare from some of you

You will loose top end anytime you go up on the rear sprocket, 3 teeth in the rear is very close to the same change as one tooth in the front. You will cetrainly gain acceleration, but your top end will loose just as much as your gain.

I just finnished putting the bike back together and this thing really pulls hard.It comes off the ground at will and I'ts like a whole new bike.I'm impressed with it so far but I only had time to go for a short spin will ride again and let you know how it handles.

If you're running a 40 in back with the stock 14 up front, then you've done about the same thing as putting a 13 on the front and leaving the back alone.

I have a 40 in my parss box ready to test out with my 13 up front, but I haven't gotten around to it just yet. I'm also gonna order a 12 for the front probably tomorrow. I like experimenting with the best combo for the dunes.

As for top end, I went back to the 14 up front and left the 38 in back for trail riding, and I was able to get a GPS-verified 71.6 mph out of it. With the 13/38 setup, I'm gear-limited to 65 mph.

BTW, these numbers are at an elevation of 4000' ASL.

I was also told by someone to try a 15 tooth up front with the same rear sprocket to get more top end speed does this sound right,because that set-up is basically the same as the stock gearing or is it.
