I have first hand experience with a couple of Polaris reverse installs but not a Yamaha ( I wish I had it), in the attached picture from my previous post you you see two large (bottom) gears and two smaller (top) gears. This set-up looks identical to the Polaris kits I installed. If so, you have to use these gears and not your stock. The stock chain is used. If this kit came from an SX 700 you will probably be geared low for your SRX. You would have to buy a new "inner" bottom gear (the outer gears on both top and bottom are the "reverse" gears, and thier ratio doesn't really matter). As for the chain, I'm not sure when Yamaha switch to the "hyvo" chain and gears on the SRX, I think it was 00, if this is the case you should be able to use your original chain if you like. The SX had a 13 plate chain stock.
Don't know if you are getting instructions with the kit? Here are some scans of a Polaris installation and a Yamaha reverse kit parts lay-out if they help.

Ok I've been following this thread and I have a question as to how this situation would apply to an 01 SRX
Vmaxx4 - you said "As for the chain, I'm not sure when Yamaha switch to the "hyvo" chain and gears on the SRX, I think it was 00, if this is the case you should be able to use your original chain if you like. The SX had a 13 plate chain stock." I plan to do this to my 01 eventually so.... I should be looking for a kit complete with a chain for sure since mine will be different? what exactly is different about it? And also if you were to keep the SX gearing what would the difference be? lower top end.... shitty acceleration?
Sorry Chilli, not tryin to Hyjack your thread...... 
Thanks guys

98-99 srx use's a 15 plate chain and 00-02 the 13 hyvo. So you should use the sx gearing. My reverse is from a viper witch also have the hyvo.

Yup, cable is on its way to me.
As for gearing, I am either using the gears/chain that came with the sx700 setup, esle reudsing my gears, and adding the revese setup (if thats even possible)
Side note, my chaincase had a crack in it, so thats why I opted to completely swap everything, just for reliability. If I have to use the sx gears, Im OK with that, but Id hate to lose the top end and the higher speeds at high rpms but....
This is all just theory as of now, old chaincase is removed completely, and I will be opening up the top end too this weekend, so I can get what I need ordered and on their way.
PS - if I am using the ebrake for reverse, I may as well remove the ebrake assembly all together right? its not doing anything, and adding weifht (I add enough already)

So then when doing this on an 01 SRX I should try to fing a setup from a viper rather than an SX? What years? Same as the SRX, 00-02? Did you use the gears from the viper?

The three more teeth on the bottom sprocket is approx like dropping 1 tooth on the top. Here's a link to some reading on chains.

Yes! Viper would work best for you (02-04). Just swap the vipers 22th with your 23th and you will be fine if your track is std.? With higher lugs i would go with the 22.DeviantSRX said:
My reverse is a mountin viper with a 21/40 gearing. So i'm gonna go with 23/40!
I think that would work fine with my 1,25" studded track. Good luck!

ok, so there is no way to reuse my big gear. The big gear from the SX has the notch in it to receive the other gear/shaft, and my stock one does not
SO, the people that have actually done this, and used the ebrake lever thing, I have a few questions? How much of the linkage assembly is removed from the chaincase? Where would the end of the cable attach to, the lever right on the chaincasie cover?
How much loss and I going to see in top speed? and what OTHER types of yammy big gear would work with this reverse setep?

i still have all the ebrake hooked to mine ...i can snap pics for you of mine so u have a model to look at ...or u have to get ahold of betheviper he has made several probably .....

If you could snap some, that'd be great.
So, I guess engaging the parking brake level makes it go to reverse no problem, but when you push the lever back, what makes it come OUT of reverse? Is there enough spring on the reverse gear to pop it out of reverse when you disengage the lever?
This is the part I am wondering about, as obviously PULLING the cable engages reverse, but is there enough spring to pop it out of reverse when you flick the lever the other way?
If so, I can likely LOSE all the linkage and stuff, and attach the cable right to the lever on the side of the chain case

yes the reverse is spring loaded and comes out when lever is fliped .....ill snap u some pics later today cause actually u are in luck cause i have it all pulled from the sled ....

So I got the chaincase installed tonight, assembled the gears and everything…few things missing from the parts I got, nothing major…1 washer, 1 spring between the spider gears or whatever they are called.
Now that YA*AM*A*HEAD hooked me up with some sweet pics, I know what I need to make to mount the cable.
Looking forward to seeing this in action, it will be pretty friggin slick…sleeper reverse…..lol

...all the credit has to go to betheviper ...he should have copyrighted and sold this aftermarket ...i have sent you a few more pictures with measurements for that part ....

so, LOL, does anybody have one of these brackets lying around???
I have contacted a machine shop here (im no welder/fabber) but they are busy right now
Does anybody have detailed spc, measurements for this bracket??
IM SO CLOSE!!!

Havent had a chance to check out the progress on this thread in a while so first off - thanks to all the guys that chimed in on my gear/chain question, definately keepin that info handy.
Chilli - will ya hurry up and get that thing done!!! j/k Seems like its a little more work that we were originally thought, huh?
I wanna see how it looks when its done, it should be sweet!! Sleeper reverse!!

yeah, the chaincase and gears and everything all went in no problems, I need to shave off the battery mount on the case cover. Glad I dont run stock can, it would be very very tight, but the dynoport allows some wiggle room.
All this work could be short lived if this Sx700 gearing kills too much performance...I may have to go back to stock, else find another "reverse ready" big gear wich matches the gearing from my stocker

gearing should be good i was told you have the same as i have i belive ....if the gearing aint what you want you will need to get the viper gears and chain to keep the reverse ....i can see what it would cost to have the bracket made for you i know a welder at the machine shop .....i just dont know were the peice that holds the end of cable come from ill go now and see what the shop says ....

well, yammy has a part number for that piece that holds the cable, I checked the dealership here but they dont have it 90249-06009-00
The proplem is I dont have one to copy. I guess I could make one out of cardboard like I have done in the past....
Everything seems to be very specific and if I have this new brake cable, I assume the tolerance is pretty tight.
From reviewing the pictures, I see that all the ball-joint style linkages have been removed, and the cable thing would mount right to the C shaped thing on the reverse actuator.
So correct me if any of this is wrong:
1 - shed all the linkage, cable will mount right to the brass C shaped actuator for the reverse
2 - the part that the cable pin connects to comes from cutting off the tip of the ebrake thing
3 - the cable doesnt work like normal, but the PIN itself does the actuating of the revrese, not the END of the cable that moves. The END of the cable goes into the fabbed mount and stays put, whereas the PIN does the actual movement of the reverse actuator
