I am not sure what gearing you should run with your setup and for drag racing....

I do know though that your never going to get a 35 rear to fit on the sprocket hub. Atleast the stock one.
Every 36 I have heard of has clearane problems with the sprocket hub...your chain will role over the sprocket hubs fingers.
37 is the lowest you can go safely....but once again, with the stock sprocket hub. You would have to make up a custom setup, as EVERY yfz or 700 rear sprocket your going to buy is going to have the same bolt pattern...and having a different yfz or 700 sprocket hub isnt going to gain you anything...you'll still have clearance issues.

Maybe go with 22's in the rear....that adds weight usually, but will significantly lower your gearing ratio!
It would be like running a 16/37 and 20's.

Good luck! :thumbsup:

yeah....your geared pretty dang tall as it is right now!

If they are true 22's, you are geared to a capable 112mph

If you go to a 37 rear with those mods, you will be geared to 115mph!

If you are hillshooting or really drag racing at all for that matter you will probably want to gear down not up. Running 22" haulers will already have you geared up as it is so I would start with stock gearing and go down from there.

Yeah the 22's will give you a higher gear ratio.

Sunstar makes a 16 tooth front for the raptor. K&K ATV carries them. I don't run it, but I do have a 36 tooth rear with no clearance problem (no contact) with the stock sprocket hub. A 35 tooth would not fit though, that's for certain. The 16 tooth front will require that you remove the case guard (and maybe even grind down the case guard mounting bosses on the case) for clearance.

Thats interesting...who makes it.

I have seen, heard, and experienced a lot of problems with trying to go to a 36 rear. On the yfz though, but the yfz and 700 share the exact same sprocket hub.....

The 36 tooth rear I'm running is just a cheapo stamped steel unit from Rocky Mtn ATV, house brand they call Primary Drive. I haven't seen a 36 in any of the spendy aluminum alloy rears, but this one just fits, doesn't touch the hub. K&K has a "no-name" 36 tooth steel rear sprocket, too. Listed for the yfz. Don't know if it's stamped or machined (probably stamped since they don't say otherwise). Rocky Mtn's is cheaper.

cool, good to know.

I was talking to sidewinder the other day, and they are iffy on even selling a 36 to you for the 700 or yfz.
Must be just the slightest difference.

I to run the 36T form primary drive got it at RM to. No problem here, tight fit but doesn't rub on anything.

A guy could always grind a mm or so off the hub fingers if he had to in order to get another brand to fit. It's so close that I can see some other brand needing just a hair taken off the hub to keep the chain from contacting it (I see now that Renthal makes a 36 tooth lightweight rear, don't know if it fits). Personally I don't like spending more for a part that won't last as long (aluminum alloy vs steel). Btw, even titanium can't be hardened to nearly the hardness of the hardest grades of steel. (I doubt that the cheapo primary drive sprocket is the hardest grade but you get my point of cost/value.) A machined nickel chomoly sprocket is probably best for wear, and that includes wear on the chain since a chain gets ruined pretty quickly if you run it on a worn sprocket. That's when the cursing starts.
