Much to my dismay, I found out today that Sprocket Specialists won't make a rear sprocket for the Predator larger than a 40-tooth. I couldn't find out why. My best guess is that it won't clear the skidplate. If so, that's a lame reason because I was already anticipating that.

So, I changed my order from a 41 to a 40 and then I'll hammer 'em for a larger one if I need it.

Can somebody possibly help me? I want to know what is better. I ride mostly on trails but do ride on sand too. What is better, going to down in the fron sprocket or up in the rear? I am kinda retarded when it comes to stuff like this and hope to learn more. Thanks in advance!

Well, dropping a tooth up front is the rough equivelent of adding three teeth to the rear, if that helps any.

For trail riding, I would leave it stock or maybe go up one tooth in back (to a 38).

For dunes, I would drop one tooth in the front, and maybe also add a tooth in the rear depending on how steep the dunes are where you're riding.

If you do both often enough, try dropping a tooth up front and see if you like it on the trails enough. I went riding today on dirt for the first time in a month and a half, and I'm running 13/38 gearing (stock is 14/37) and I do NOT like it for dirt... it's way too short. But it's awesome in the sand!

Hey Rob what would happen for the sand if I just went up to a 38 in the rear? What do you mean by the 13 is to short? Do I also get more torq with going to a 38?

I need help so I'm bumping..Sorry.

Any gear change (shorter gearing, which is down a tooth in front, or up one or more teeth in rear) will help in the sand. On dirt, all it does is make the motor rev faster, which can cost traction.

Torque doesn't change with gearing... rather, how soon you get to the torque does. It "feels" like it has more torque when you do that.

As inexpensive as sprockets are, I suggest that people just TRY IT. It's easy to change back to stock if you don't like it. The 13T front is $15 and a rear sprocket is $29 (the 38T from Polaris) and about $50 for the 40T from SS.

Thanks alot Rob. I will just try it out. And about the Torq thing, you got it right it just "feels" like torq and that what I meant. Thank you !

Hey Chris....
How does the dial a jet work?
Have you modified your airbox at all?
Thanks
Tres

 

[chaos_134]

No I haven't modified the airbox yet. I am thinking of the Jet airbox kit from superbikeshop. If it helps with more power and torq why not? The dial-a-jet is pretty dang cool though. I put one on and helped my buddy with putting one on his Z-400. The throttle response is awesome. I really felt it on his. The Pred throttle response was pretty good already I thought. Did get better though.

Like it was said, at least get the 38 for the rear. Works great for all around riding.

 

[chaos_134]

Did it, now just waiting on nice weather to put it on and try er out.

I finally got my 40-tooth, which will go on before my next trip to the dunes.

I think the best gearing for dirt is either stock, or +1 in back (14/38). I tried running my 13/38 on the dirt and it sucks. Bad.
