Anyone have a web address to someone that sells an 11 tooth countershaft sprocket for a Raptor...?

TIA,

JPBRaptor

Man, you gotta be nuts to go with an 11-tooth! Forget about any chain or sprocket life, and it is just plain hard on the drivetrain. Use your head and go with a larger rear sprocket instead. With the torque that the 660 motor puts out, I cannot imagine anyone needing to go that low on gearing anyway. I solved my "problem" by selling my 2001 and getting a 2002 model...much nicer gear spacing and I don't feel like I need to change the gearing at all. It has a very adequate first gear as compared to the old model.

Thanks for the web address Raptorrider2001, got it ordered today...

And Scottd, there are several reasons for me needing to gear that low, one I'm going to be running taller tires than stock because I need the extra ground clearance at the rear sprocket and brake rotor, which means putting on a bigger rear sprocket would defeat what I'm trying to acomplish. I also need to be able to travel at very slow speeds for long periods of time as me and a buddy plan to cross many miles of very rough mountain terrain that has never been crossed before. But thanks for assuming I'm an idiot in need of your enlightment, and remeber the next time you "cannot imagine", there are many of us out here who can imagine!

Hey scottd, would you PLEASE enlighten everyone one on this board why putting an 11 tooth front sprocket on a Raptor will be harmful to the drive train and diminish chain and sprocket life? I would LOVE to hear your explanation. Need something to put on the bulletin board in the shop.

JPBRAPTOR,

I set up my Raptor the way I did for the exact reasons you used (technical mountain trails). I decided to compromise and stick with the 12 tooth sprocket and 22 inch Razr's so that I didn't lose any more top speed. The E-series slip on gave me enough more low end torque that I rarely need a lower first gear ratio (although it does happen occasionally). Since I spend quite a bit of time on fire roads (forest roads) between trails, I figured an 11 tooth sprocket would cost me too much top end. I can top out in 5th somewhat easily on forest roads with the 12 tooth now. It's pretty scary coming up on a jeep on the wrong side of the road in a fast corner.. ( I've slowed down a bit after the second time it happened). It was a lot easier to miss hitting some one when I was on a dirt bike than it is on an ATV :*). I would like to hear how the 11 tooth works for you. I didn't want to raise the size of the rear sprocket and lose ground clearance either. There's a guy here on the forum that I discussed this with, and he ended up having to space the skid plate down to clear his larger rear sprocket so much that he lost most of the additional ground clearance he gained with the 22 inch tires. I'm sure that you'll have to take a link out of the chain for the 11 tooth, I was able to get away with out that for the 12 tooth.

Good luck,
Lorrin

A 11 tooth was the first gear change I made and ran it a long time for the same reason you are wanting to run it. 2-5 gears are a dream with the 11. You do lose top end, but that is not what I was after. I had enough adjustment on the chain that I didn't have to break it and make changes although it was adjusted out about as far as it would go. The 11 makes it very easy to ride in the really rough stuff without having to slip the clutch when you get into a bind. The clutch was always getting hot and slipping to the point I would have none at all and have to wait for it to cool down. With the 11, the chain lays very close to the large locking flange on the large gland nut and after a while I became concerned that it may be rubbing on it so I changed to a 12 and went to a 42 on the rear. I had to add some shims on the rear to clear the swing arm cover and did give up some ground clearance. I ended up with 4 flat washers on each side as shims. Let me know how it works out for you.

By the way, what part of Oklahoma do you live in or ride in?

LEEL,

Thanks for the info, and I wish I could use a slip on muffler to help out the lower end torque, but right now they are all too loud for me. I ride where there are a lot more hunters and campers than there are quad riders, so I prefere to be quiet (don't need any more enemies, especially ones with guns :-). During normal trail riding the 12 tooth does the job just fine and like you say is a great comprimise, but we have a ride planned where we will cross a mountain that has no trail on it, this will mean long slow miles around trees through creeks, over many rocks, and I'll be very surprised if we even get to 3rd gear for this ride, that is why I want to run the 11 tooth. After that ride I may not need it again for a long time...

Raptorrider2001,

I live just south of Tulsa, and we ride trails in the Ouachita National Forest in Heavner Oklahoma (in south eastern Oklahoma). We also ride dunes at Little Shahara State Park which is just south of Waynoka Oklahoma (that would be in the north west part of the state if you exculded the pan handle) Thanks again guys for all the info, and I'll let you know how it goes...!
