A Really bad noise

[LazyBastard]

NEVER EVER lock it up like that, it always leaves the belt down low in the secondary. Always let it roll to a stop.

Sound like don't use it to me.

Always let it roll to a stop.

MMMMMMMMMMMMMM

The key words are LOCK IT UP

Use the brakes all you like, just don't friggin LOCK IT.
ON ANY BRAND.
THEY WILL ALL DO THE SAME.

I guess thats why they invented ABS, for people like you.

Strange - I have always pounded the crap out of my brakes. Lock em up all the time on all of the sleds I have owned and I have never had an issue. Although this is my first Yami - maybe it has to be babied

The RX-1 does need anti-locks though, about the only place I really notice the extra weight is under braking.

Actually, I have always pounded the crap out of my brakes also. I have only ever owned Yamahas. My SRX(00 w/10,000 miles) never makes the sounds the RX secondarys make. It also has a ripsaw 136". I just think its a completely different beast. However I do not think it will hurt anything on the Rx's. Just don't nail after locking them up, ease into the throttle.

The brakes on a sled are like on anything else they are more eff. when you don't lock them up, if you lock it up you'll slide farther thus coming closer to what you don't want to hit. If your just playing lock it up all u want just let off a little before you stop so the track can turn to get belt back up in the secondary.

I lock my brake up at intervals all the time cominhg down steep grades and sometimes to slip the rear end around a corner faster. If you have a grinding noise after locking up the track, you should be finding out what's causing it. Check your chain tension and track allignment and tension.

This sounds similar to me in December. It was a knocking sound and the clutch appeared to be frozen up. I had notched the belt as I stupidly didn't pull my track off the ground where it sat overnight. I didn't ever think that it could be the belt. I checked the chain case, the oil level, the clutch without the belt on, changed the belt out and ran like a champ.

Unless you have a roller, think of it as driving a '70 Volare on ice - Pump the brake lever or gradually apply it, but NEVER lock it up into a slide or you know what will happen You'll hear the squeeling dog - or in our case the squeeling pig.

I've had Yamahas for years, and locking the brakes and sliding the sled around to make a u-turn in the trail is something I've done hundreds of times. I've never encountered this type of noise before. It doesn't make sense that this is a problem with the Warrior, but then this is my first 4-stroke.
I'll admit that the secondary could be staying open, that makes sense also, but why on this sled and not the others?
If the secondary is staying open, then that accounts for why I could slide the belt off so easliy.
Perhaps I will tighten the secondary spring up a bit. That should help.

Thanks to all for your replies.

On my last trip same thing happen. I had to apply full break to avoid my friend in front who had to stop rapidly. When startiing again I could hear that grinding sound...Open the hood, and notice the belt was loose and not on top. Stop the engine and play with the driven..Start her again, then complete my 300 mi. journey. with no problem. My dealer told me that I might need a good clutch cleaning, which I just did, by the way I just hit 5000mi. first time cleaning it. Also put a new belt...Tomorrow I'm leaving for another 1000mi. ride. Let you know it happen again.

Well 1100+ mi. later, the malfunction of secondary didn't happen again...So the cleaning version was the right solution for that problem.

It is not a Yamaha thing.
It is a technique,
-if you apply brake the while still on the throttle ie primary clutch squeezing secondary open then let off the throttle the primary opens but the secondery will not close as belt is stuck down in it.
If this is does not happen unless you lock up the brake this is it, if it happens when you roll to a stop -brake on or not- then I agree look at chain case.
By the way my goal when breaking HARD is to keep track rolling at the speed that slows me down most effeciently that is Never locked up.
