I've been locking down my SRX secondary for the last two seasons as a stocker (Grass-Dragging/Trail Riding) and raced it on the tar this past summer. I use the secondary belt deflector as well. I definitely think there is an advantage. When you pull up to race it's always in the correct position. My personal take on this is that yamaha is covering there but on motors that move. The 03-Viper is a good example on this. The motor mounts were/are not adequate for that motor. I seen two of them break myself. And this was on a stocker. When this was first reveled to the public, yamaha said, 'It's supposed to work that way..." hmmmm. Almost all the guys I know that tune their Vipers have put the stabilizing-bar on the motor, just like the SRX. The big drawback is that you need to keep on top of your clutch alignment. I use an alignment tool. I checked it after every race. My sled has over 4500mi on it. The new motor has about 30miles on it, however it's has a lot more power than the stocker. I will continue to check it. If this becomes a problem I will post and let all the fellow TY-ers know what's-up...
As for the RX... I have a warrior and will do some experimenting this winter and see if it makes a difference… No ‘snow’ miles :wink: on the Warrior yet…
Matt, Great subject… Hope my real-world results helps.

I agree with JTSSRX, secondary floats to save bearings, and they will self align. Also, I have a 2001 Polaris 600XC, it has float as did my 200 ZR600.
Everyone makes some awesome points, and i think this is a great topic to debate. Viper34, My F5 has a factory locked secondary, all 04 polaris high performance sleds are locked and Every Ski-Doo is locked. I ran Ski-Doo from 93-2000 and never had belt life issues and never had jackshaft bearing issues.
jtssrx, your points are good as well, however explain how Ski-Doo customers dont complain about jackshaft bearing failures?
I have run locked secondarys on my Yamahas and have never had bearing issues and increased my normal belt wear on my 00 SRX from 1 in 400 miles, to 1 that lasted the remainder of the time I owned it.
Certainly Yamaha does things for a reason, Suspension, Clutching...etc, however this is my opinion only and was just passing it along to anyone interested. I also run the belt adjuster and love it, and if you do, you have no choice but to lock your secondary.

Sounds like you guys really need an expert opinion here so I would like to contribute.......
But before I do...Where the hell is the secondary clutch :?: .... :lol: :lol: :lol:
KIDDING I'm kidding.....!!!! Good post Matt...as we have also discussed on the phone. Your theory is sound however, with my track record woth machines, I will leave everything on my machine as is.

BlueByYou2000: I'm speaking of long term failures. The RX-1 makes 65% more torque then anything ever built on the bottom. This is where you are really loading the secondary out of the whole. I know Mark Miciare "THE HAMMER" Had jachshaft problems with a locked secondary.
When you lock it the secondary automaticly loads the jackshaft with eeery inch of torque. when it floats it releives some of the torque. That's wy it translates a power loss with it unlocked.
I like a locked secondary!!!!

there is a difference in limiting the side motion of the secondary clutch and side loading the jackshaft or chaincase bearings, side loading will cause excessive friction and premature bearing wear, i believe that matt is telling you to elliminate excessive side movement, rather than to "side load" the bearing. the clutches will not self align under load, and with a good engine tension, and a "fixed" or "locked" secondary position, power will be transfered with higher efficency. good post matt, its nice to read constructive posts such as this one. jeff

My rx1 had bearing failure in 2100 miles. They say the 04's have a different bearing and shaft I guess. I waunder the 03 's have too much side load from the way it's designed drawing it towards the chain case.
