Ok im buying new sprockets I currently run 12 up front and stock 40 on back. I have a Raptor and I do trails,hills,Muddy trails,jumps,creeks. So what sizes should I go with? Or should I just keep the same sizes.

 

I run 12/42 and like it very much. Similar riding as yourself and dunes. Pulls strong through 5th gear. Loose some top end but a good trade off for me. Even a 12/41 would be a good combo. Just my opinion. I hav been trying a 13/42 recently but am going back to the 12/42.

 

I run a 14/40 on my Raptor and really like it. If you go to my photos page I have a chart that will show you all the effect you will see by ANY combination of gear ratios. You will find it in my "Raptor Mods" folder. I hope it helps you out.[img]i/expressions/face-icon-small-happy.gif[/img]

 

If you want to go that fast,sell both snowmobiles on wheels and put the money in the raptor.Then you'll have something.speed with power to boot! Hi,Greg V.

 

Is your Raptor a 01 or 02?This makes a huge difference.

 

Hey Turbo33-1/3rd.,[img]i/expressions/face-icon-small-happy.gif[/img] (I am tooling up my Raptor, Mo Faster)

You may want to just go a little larger on your rear sproket.......maybe a 42 or 44. That should give you a little more grunt.[img]i/expressions/face-icon-small-happy.gif[/img]

I have a couple of friends that have Cannondales (FX400's) they don't seem to have any trouble in the woods & hills. You may just want to just wait and see if you have a problem before you change it. Gearing affects things across the whole range, you may regret chaning it if you get into a situation when you want to crank it up and your top end is gone. Just my oppinion.
