SLP Triple Pipe Install Questions, Need Pics if You Have Them

Too bad you weren't closer, you could just pop my clutch on and see if it doesn't flat out work. Today I picked up a tall clutch cover, a YGY spring, and some 16mm rollers. I also found some 8DF weights on eBay for $40 so snatched those. When they arrive I can try that combo. In the meantime I just need to see what happens when I redistribute the weight in the primaries I have now.

I've got a friend with a lot of yamaha sleds nearby, I can try one of his out possibly.

I'll be interested in what results come of the cover and spring change.

More warm weather coming this week so snow will be worse yet soon. We could use 20-30cm. Its deep enough currently but like riding on a glacier.
 
I went out to my friend's farm today and robbed the clutch off his VMax 700.

It was filthy so I ran it through the ultrasonic cleaner as well.

It's a short cover with 8CH weights, and GPG spring.

I'm going to swap my tall cover, stock YGY spring and 89L weights onto it and take it for a rip tomorrow.

It was +5C and sunny here today so our snow is more ice than anything. Back to -7C for a high tomorrow.

Hopefully I'll have a couple updates by noon.
 
I tossed the 3.3g inner rivets today in favor of 2g in that location myself. Didn't test that yet. My 8DF weights are also almost here. But I think tomorrow I'm grabbing an SRX for the kids. . . it's a 120.
 
Well I tried with that other clutch out as well as the Thunder's blue secondary spring and not much changed.

It's -7C currently.

I put my tall cover and YGY spring on the other clutch with both the 89L and 8CR weights empty.

Same situation, with a touch more rpm out of the blue spring. The 89Ls are at 8000rpm WOT and the 8CRs are at 8500-8600 WOT.

Trails were groomed yesterday, and are flat and basically like ice.

Both weights peaked at 120-125KM/HR on long WOT pulls, even though there was a 500rpm difference between them.

I'm officially out of ideas for clutching.

Perhaps its the jetting or something, not sure.
I've got two rides to go on next Friday and Saturday amd another one with the wife two weeks later, so I'm probably going to put it back to stock for the remainder of the winter.
 
I pulled the pipes off, out the single apipe and MBRP can back on.

Stock carb configuration.

Stock weights and stock YGY (tall) spring but 14.5mm rollers vs the Stock 16mm.

Kept the RX-1 helix and Thunder blue spring at 70 degrees.

The sled just runs so much better. Hits 8400, doesn't peak higher, shift curve is dead flat, keeps the skizin the air unless you spin, or until speed picks up. Hit 145km/hr very fast. Trails are super flat and smooth but very icy with deep grooves from the groomer. Still some speed on the table, terrifying going that fast and the back end kicks out, I have a 1.25" track and 0 studs.

It'll likely stay set up this way the remainder of the winter.

I talked to a guy that used to work for SLP today that tells me my pipes are for a 600, not a 700. As far as I'm aware the 09-727 SLP pipes are for both 600's and 700's. Did SLP ever make pipes specifically for the 600's?

The way the fit seems a touch off and the way that the sled acts with the pipes has me wondering if that's actually true and they're maybe a bit restrictive.
 
My experience with the 8DN-10 has been night and day different than the 8CR or 8CH. Every time I thought I had a carb issue it ended up being clutching. I got my 8DF-00 weights today and they look VERY simliar to the 8DN-10, but I expected this. I imagine that's what's in your sled now that you're back to stock? Mine was 8CH stock. 8DF-00 or 8DF-10 should be it for a 2000 SXR 700. I've been thinking I may end up with a heavier rivet in the tip of these 8DN-10 weights vs the inner hole and that's exactly how the 8DF showed up which confirms my suspicion, but we'll see. 145kmh is exactly what mine would run with a single pipe, stock clutching, and 1.25" track but when it's hitting 9000 or better it's 160+ all day long. It's MUCH happier to overrev than underrev. If I were you I'd prepare to start over with a different primary weight altogether and throw what SLP had suggested right out the window in terms of primary clutching.
 
Honestly I've burnt myself out of ambition with these pipes. Post a photo of what your pipes look like, specifically near the muffler just out of curiosity.

I dom't understand how I could be so short on RPM with empty weights that a lot of people have used with good success and have needed more weight.

If I was close but just a bit off that'd give me ambition to continue trying.

Remind me what your jetting specs and such are as well please.
 
Mine are different than yours, I have 3 glasspacks.

I saw nothing but complaints about the 8CH and 8CR doing exactly what they did to me with the pipes, they're not a straight shifting weight. They scream off the line and dump RPM up top. I was nudged toward the 8DN-20, was told it would like a straight helix, and voila here I am (even if I went with the 10 cuz I found a deal) shifting by the gram and half gram on the rivets to dial it in right where I want it. I figured since this sled is used as I envision the SRX was optimized for it would be a good weight for me. I have no idea what this thing will do from a dig right now, haven't yet tried. Probably should, my friend with his MachI is going to want to run from a dig and that would be a lame way to lose knowing I can wax him everywhere else.

Take a close look 8CR and the 89L, they both have the mass unevenly distributed. They both inherently have a lot of tip weight when compared to early on in the shift curve. The 8DN-10/20 and 8DF weights are much more evenly distributed from the get go. Of course each weight has its own unique shape that hits the rollers. But adding rivets to a weight that already has all its mass out near the tip will only murder your RPM once some speed is built up.
 
Interesting. All good info to consider.

I am curious what the difference between your pipes and mine are. I didn't realize SLP offered a stinger set up like that, I thought the three into one muffler was the only option. Concidering this was 75% just for the good triple triple noises, yours probably sounds way better haha
 
It's a harsher sound, really makes you want to do the Tim Taylor grunt. Has a hint of SRX with a can and ZRT/TCAT to it. Definitely its own sound, not as smooth as a single pipe even with a can. Tough to capture too, I have GoPro footage but it's up over my helmet with a sealed case that mutes the sound a bit. Used that to verify what I thought I saw on the tach vs what the tach was actually showing. It was also a useful measuring stick for comparing to others on YouTube who post snowmobile vids. It's apparent why I don't get passed on the trail.

I was very frustrated for a few weeks last season myself as the thing is weaker than stock when off the pipe. A stock 600 twin could have waxed me on a full trail ride with the empty 8CR weights. But this year when the 8DN weights had a chance to shine in actual winter temps and I got to feel what it was really going to be like I knew there was no going back. The acceleration is much stronger corner to corner. In the tight stuff before where I would come into a corner say at 80 now I was coming in at 90+, sled is definitely a bigger handful but since both ends have traction it works. Just a bit of a different animal is all. Really puts a smile on my face.
