XTX gear

[ATV PRO #11]

68 mph or 110km/h is all I've seen in mine. No idea on rpms. 14 xtx as well. Dream meter.
Looking on schmidts utube vids (remember while shopping for exhaust system) they were hitting 93 mph at 11300-11400rpm. (Single exhaust Phazer vid, 3/4 through vid.)
Definately will be looking into this once I see rpm with new system installed.

I have seen 142km (88mph) on a lake. Hang on Marty, you're about to see some serious s*#t!!!

Really? I thought it would be faster then that. I was running around 130km on the river and on the way back from South Beach 135km. On the way back from SB. I was keeping up but not on the river. Lol.

Interesting. It felt quicker but now that I think about it I took a gps with me. Also Brian, srxtwins, said he was doing 160 in a couple fields we were taking and I was not far behind him. Our River south beach run I was flat out, corners and all. I think next time your out we should cross this bridge.

Ya, I've had mine to 143km here and there for short burst. But I never hold it to the pin, maybe we can play around with my setup one day.

Got the sled back in my garage. Got some time to look at it. Removed left side cover and guard. Removed the belt. Compressed the primary with my hands and looked at the Primary weights. It has 86C on the fly weight. The fly weight has three unmarked rivets or weights in it. Everything in the motor, exhaust, intake, clutch is stock. I would just like to get the RPMs down and get more speed out of it. The dealer said I should just buy an aftermarket clutch kit to get it off of the rev limiter. I don't want to void the warranty.

Has any one worked with the stock clutch setup and gotten it to work good?

I would say it will be rode 90% trail. Some of our trails are on a rail bed. So 65 mph top speed on the dreamometer is a bit slow when riding with apexs. We also get a lot of drifts. That's where this sled should really shine for having fun!!!

Also clutch engagement is around 4,850. It seems a bit high and jumpy. Fine for launching out of the hole. but sucks when backing up or loading. Is there anything to be done on a stock clutch to get this fixed? or do you have to go with the many after market clutch kits available?

From what I am reading I should not be running out of gear at 65 on the dreamometer, just needs more weight on the clutch.

Thanks for any info!

I believe you can go up to 1.5".

I have a 1-7/8 Polaris snowcross track on my 121 with tons of clearance on the heat exchanger

68 here max, Then bolted the Hindle on and saw 74 with more left. Smelt sliders. Shame on me, I wasn't watching the RPM's.

I do not want to put any exhaust on my phazer. My borthers and a few others have put exhaust on theirs. I am growing out of the loud exhaust phase of my life. Only thing I want to try right now is to get my clutching set so the RPMs come down a bit. And hopefully get some more top end when it shifts up to use all of the power. With lower RPMs I would think that it should get better MPG. I also would like to get the clutch engagement lower if I could. possibly more weight on fly weights, softer primary spring, or looser secondary spring.
For clutching engagement I know adjusting the secondary will not change that.
I am not a clutching expert at all!
My cousin had hauk exhaust on his phazer. My brothers had excell. They sounded alright. Still not as good as the apex sounds with exhaust! But with age comes less and less need for loud exhaust. And land owners don't always like to hear a sled barking down the trail waking them up. But don't get me wrong, I do love the beautiful sound of a motor talking to you making peak HP.
Any help with this would be great! Love this site!

Thanks!

Can totally respect that OneGuy!! I'm watching "Nos'" Phazer build thread. Learning about clutching as well. My 07 I just fueled and rode. Rode lots!!

Never seen the 86C weights, do the rivets look like Aluminum or Steel? If some are aluminum then you probibly have enough room to added enough weight to bring the RPMs down. OR grab the Ulmer Racing kit and save your stock weights to toss back in for "warrenty" work. BTW, my motor blew under warrenty and they said nothing about the modified clutching or aftermarket exhaust on mine. Motor blew due to a defective rod

I know I will not have a problem with my dealership getting anything covered under warranty. But if has issues while on a trip or say my dealership would go under. I don't what it to void the warranty. As it this does clearly void it. I just want to eliminate any grey areas. I would guess most dealerships wouldn't have a problem with it. But I don't want to chance it. Right now I am writing warranty claims for agriculture products. So I read the warranty that came with the phazer. That's why I am a little on the safe side.

The weights look like steel. Is there a clutch section or thread somewhere on this site that has all weights, springs, settings, and what the changes do? I feel like there is, but I can not find a chart or guide as to all of the different clutching options. I started asking my questions on this thread as I didn't know if it was a gearing issue. Now I might need to move to a clutching thread for better results?

It almost seems like you have to buy a clutch kit for these sleds and ditch the Yamaha setup. Just hoping I was not the only one having an issue,and that someone had a good idea of how to make the stock clutching perform better without buying an aftermarket clutch kit.

I have read clutching threads for a few hours today. I feel I need more weight on my fly weights. Not sure what comes on my sled stock. Hopefully my dealer should know what it has stock and go bigger from there. My secondary was in the second to last soft setting. I moved it to the last soft setting. Don't remember the number letter combo. I was looking at a chart from this site. I will see if that helps. But from what I am reading this will not help my high rpms. From what I am reading I set my RPMs with the primary. And set the way the clutch shifts when you play with the throttle on the secondary. If and when I get it figured out I will start a new post with what I have found. I am sure there are more XTX riders out there with this same issue. My goal is to get it working great with the stock Yamaha clutching. This should be cheap if I don't need to buy springs and just weights. Not only will it be cheap but it will not void the warranty at all.

Stock A1
Took out 10* to C1 (secondary)
I gained 5km/h and dropped 200rpm.
Lots of rev-limiter in soft stuff, good pull through mid range.

Any updates on where your at? I'm still reading and on the fence what route i'm going to take.

I have done some testing with the clutching. I also loosened up the secondary. It seemed to drop the rpm for me. But the secondary seemed to be too active. It would be shifted up and cause the motor to bog down. It also slipped the belt a lot below 20 mph. Some times it would slip the belt up to 30 mph. So I ordered the largest fly weight rivets Yamaha had. I ordered 6 of them. My fly weights have 3 rivets in them. First I drilled out the tip rivet and replaced it with the larger ordered rivet. This helped a lot. I had the secondary in the stock location. The my girl friend and I went out for a ride. I borrowed my brothers phazer. This was really nice. That way I could compare the two sleds. One thing I noticed right away is that my XTX read a lot slower speed on the dreamometer. His read much higher. I got 92 mph out of his. My XTX topped out at 75 with the added weight in the tip. That was at 12,500 rpm WOT. Also with regular riding his phazer used around 1/4 throttle. Where mine to maintain similar trail speeds was using 3/4 throttle. His also has pulled very hard up to 60 mph. Where mine revved up and slowly accelerated. I was still not fully impressed with my clutching so the next night I removed the middle fly rivet and added the large one from Yamaha. I test drove it that night. I was much more impressed with how it performed! I was able to get 82 on my dreamometer. 12,300rpm WOT. It also required less throttle to maintain trail speeds. This was with the secondary in the stock location. I changed the suspension setup from stock to improve the handling. My sled came with the front spring rate maxed out, front skid shock maxed out, and rear spring set on soft. This had a very stiff ride. It also had lots of ski lift with a high CG. What I did was back the front shocks off to about half way on spring pressure, backed the front spring off so the spring was just applying pressure when the rear skid was off the ground, and the rear spring to hard. This improved things drastically. It cornered so much better with the front end lowered. It soaked up bumps very well. Yet it still transferred weight and picked up the skis when you wanted. Made for a very plush and fun ride. I do believe my brothers sled has a hauk clutch kit on it. With my alterations I feel my clutching is acceptable. It is as fast as my brothers if not faster on top end. But my alterations still do not pull as hard as my brothers off the line. And I still use more throttle than my brothers. So his may get better fuel mileage with the clutch kit. If I were to try more with this clutch I would want a softer primary spring or a bigger fly weight and work with smaller rivets. But I had an oops last night. While a group of us were riding I managed to catch a gate. We were riding on the trail. One of the gates to close the trail blew in to the trail. It swong out just missing the guy in front of me. But hit my sled. It was a gate on the right hand side of the trail. It hit the right side of the sled. Dented the oil tank a little bit. Cut open the right plastic panel. Smashed the battery into the brake disk. Hit the gas tank cover. Then cut through the seat. It hit my knee, knocked me off my sled, broke my helmet, and may have broke some ribs. Got very lucky. so for now I will be working fixing the damage from hitting the gate. To wrap things up I would say adding the two largest rivets to the tip and middle of the fly weights makes it much better. That's with the secondary in the stock location. It makes a very big difference. But I do feel a clutch kit will be the best performance. The weights are very cheap and easy. So if you want to try it. It may be worth your time. If I try anything else with clutching I will post it. For right now I am going to heal up and work on fixing the damage.
