Happy 4th weekend everyone, hope you had a great time.

I have a 2001 660 Raptor, with oversize weisco, and a hotcam, several other mods....

On my way up the mountain to watch the fireworks, I found out that my front sprocket was slipping on the chain. (what a noise). Anyway, I took off my front and rear sprocket and chain. The previous owner had replaced them. Here is what I found.

Front sprocket 11 teeth.... Wow, never heard of it before.
Rear sprocket 46 teeth.

I like the way it runs. I guess I would like more top end. But What does this combo come out to be modded for? I can run the gears pretty fast, and it will pull the wheels off the ground in 3rd gear. I guess what I am asking is, for hauling ass on trails on the property is this the correct ratio? I have 21X10X9 ITP Holeshot HD on the back.

Also, the front sprocket was wore the hell out, I mean toast. I know your all going to say it has 12 teeth, but seriously, I counted 3 times. 11. And I would think that you should replace the chain, the guide, and the rear sprocket at the same time, seeing as they all work together. But is that the proper service method??

Thanks everyone. Safe riding!!

You should replace the chain and sprockets at the same time, you're correct. The slider would kind of depend on it's condition. You're also correct in sayin that 11 tooth is crazy... I din't even know they made them ? 11/46 is REALLY REALLY low gears for that bike. I have a 12/42 combo mounted right now and IMO unless you're mostly climbing, even that is too low.

I ran a 12/40 (stock is 13/40) for a long time and really loved it. I recently bought a 41t rear and I'm gonna try the 12/41 combo next ride out. 12/40 is a GREAT combo for riding trails and riding them fast. You can really work all the gears, and you're not constantly shifting like you are with the 13/40 ( and probably your setup too I would assume ? ). You will still be able to pull the front end up with no problem witht he 12/40 as well.

Good Luck, and let us know how it goes ! :beerchug:

I have searched everywhere, And I have no idea where this 11 tooth gear came from. There are markings on it, I will post tomorrow what it says, they are at work. I know 11 is stamped on it. Along with a few letters. Very strange though.

The trails at the house are mostly short, and with alot of curves, so the way it is set up I love it. There are a few streightaways that I hit 5th in and hold it open, but not for very long, so for what I have to ride on, I like the way it is set up, it is perfect. I would like to go back the same, but if a 11 tooth gear is that uncommon, then I might just go 12..... I would guess an 11 tooth would be very expensive since its not easy to find.

Good chance it's a sprocket for something else that happened to fit alright...

I have found a 11 tooth sprocket, it is for a 250 or something. I talked to some people, and it will work for 2-4 months and then wear out, like mine did. I guess I am going to go with a 12 front and 46 rear. The maker of the sprockets turned out to be JT Sprockets. Thanks

yeah I was going to say someone must have done there research and found a bike that took the same 12t or 13t, but also came with a 11t option. I can't imagine how nasty a 11/46 is. I just changed for a 13/40 to a 12/42 and lost about have my tire life. Good luck with that.

The 12t will be a better fit/match for sure. That will make a bit of a difference, but honestly if you're looking for more top end as you said in the first post I would drop that rear to AT LEAST a 44... maybe a 42.

12/42 is low enough that you won't miss the bottom end at all, and you'll still have some top end which I can only assume now, with a 12/46 combo is very limited ? :beerchug:

Question , I have 14/38 , now I bought 15th , is this combo will change something?? I use the quad for trail / hills.

Sounds like you have a 700 ? Is that stock on the 700's?

That 15t sprocket will give you more top end, and a little less accelleration. The 15t is a pretty common mod though I think for the 700's, and if you have the supporting power mods, you might not notice the difference as far as missing low end ? I've never been on one with it though, so I couldn't say.

Now if you're on a 660, I don't think I would do a 15t, I would say 14 is the most I would do up front. I would play witht the rear sprocket size a bit before going to a 15. Though at 38t your rear is pretty small as well.

How is your 14/38 setup now ? What do you want to gain with a gear change, top speed, or accelleration ?

You can buy 11T fronts for the 660, I had one on my 05 several years ago, I think I found it on ebay but I can't remember who made it.

i went from a 40 tooth on the rear to a 37 tooth. I found out the hard way that i had to machine the sprocket hub to clear the chain while bolted on the hub. it was a pain but worth it to create more clearance out back.

Has anyone tried a 13/42 on a 660 raptor?
