Suspension settings, RTX ONLY

Okay thanks I ve heard about them. About removing the transfer blocks I m pretty sure that should sit the sled down alot more.... any worries about doing that?
 

IMHO taking the transfer blocks out will accomplish nothing for her. taking them out will allow for more transfer however that is only true if she is compressing the rear suspension far enough to hit the blocks to begin with. I'm 175-180 pounds and I could only bottom the sled out occasionally riding very hard through big time moguls. that's with it set as soft as it will go. She will not get much transfer accelerating or trying to pop the front up over bumps because she just doesn't have the body mass to compress the rear suspension. Cannondale valved mine 20% softer and that seems pretty spot on for me (thanx Cannondale ) . I also added the BOP (barn of parts) torsion block re-locater This softened up the spring action considerably. Worked fine for me at slower speeds with wife 15-35nmph in trail chatter with blocks on 2. I just took it back out for a guys trip where I know I'll be pounding it maybe a bit too soft for me at high speed. For her the BOP kit and valving is a no brainer best $$$ u can spend
 
have her sit on sled take a look at spacing between blocks and rear arm, have her jump up and down on it, bet the rear arm never contacts the blocks. That's why taking them out will not "sit the sled down" she probably only hits them riding through fairly nasty bumps at speed.
 
Hey cannondale, do you sell those front skid shocks everybody raves about?

Was out yesterday with the girlfriend. We had some very cold weather yesterday (-34) and on the way back I had to give up my ltx dx (and my heated seat) because she was cold on the rtx. I keep telling her she needs a tall windshield. Well, I nearly froze on the way back so I’ll be putting my taller windshield on her sled for todays ride.
She wants an ltx dx with a heated seat now! She also said mine rides nicer. I noticed hers is starting to soften up a bit more with a whopping 1119kms on it.

I have a few more questions, do the rear torsion springs apply ski pressure?
And are there softer springs you can buy? Is the bop relocation kit easier to install vs the springs?

Also wondering about the front skid shock, will tightening or loosening the spring apply ski pressure or not? By tightening it, will it suck up the front of the skid and apply pressure? What does that front shock actually do? Sorry for so many questions guys, just really want to try and get this sled figured out the best I can in stock form before I start spending more money on aftermarket parts and shock Revalves.
Thanks

I went full loose on that center spring trying to make it softer. Have the A arms set up well, ill try adding more turns back on the center. Still curious if anybody is running the High gear twisted set up on theses Fox QS3 ?

By backing off the spring, did that make it softer? Did you loose any ski pressure?

No just revalves,refreshes and I sell the Stingray spring

Rtx is valved stiffer but all will soften up for a good 1000mi

Yes rear torsions would add more ski pressure if cranked up but she would hate it.
Softer spring are available but not enough.
Bop relocation would help for sure.

Loosening center shock spring adds ski pressure but will not help ride. Just buy new skis.

Think of the center spring as the pivot point for the sled because that's what it is. By tightening spring you force the front of the rear suspension down lifting the center of the sled.This reduces ski pressure as the weight is now carried more by this spring than the skis. When you back the center spring off (softer) this takes sled weight off the front of the rear skid and puts more weight on the skis and rear portion of skid. so when you back that spring off softer you increase ski pressure, not reduce ski pressure.
We had a 2000 Vmax chassis phazer very light sled it darted terribly and the back was always sliding around. By softening the center shock considerably it compressed the front of the rails more and allowed the skis to now pick up some weight along with the rear of the track .After that it went much straighter.

Imagine the sled on bare pavement with a set of caster wheels right under the front of the track where the center shock is. The wheels would hold the whole sled off the ground it would want to pivot around those wheels on it's axis. When you crank up the center shock that's the effect. Though the 4 stroke is so heavy it probably wouldn't get squirrelly like that Phazer.

Yes rear springs also effect spring pressure. You put a guy who weighs 350 on that sled he will compress the rear suspension quite a bit lowering ski pressure . She can't compress the rear arm much so ski pressure will be higher.

BOB kit really softens up the rear springs and is easy to install. I ended up going back to stock though cause it was to soft at higher speeds. 1 setting on stock is a little to stiff for me but even on 3 the BOB was to soft and would bottom to easy for me. I'm 210 with gear. On smooth trails the BOB was great.

So the guys and I got away for the weekend and I decided to take out the RTX! I put the “thong” windshield on which was a mistake because I was taking all the wind in the chest and it was swirling down right into my crotch. Was a bit of a cold ride, so that will never happen again!

THE GOOD:

Anyways, this sled is a blast to ride with these QS3 shocks.
I have everything set on full soft, shocks and rear torsions.
I’m only 145lbs plus my gear, so maybe another 30??

I haven’t had this much fun on a sled in the longest time, I don’t know if it’s because I haven’t ridden that hard with the guys all season yet (due to riding at a slower pace with fiance) or if it’s just the fact I can get the #*$&@ end sliding out around corners with ease, but wow was that ever a fun 400kms.

No I’m looking back and reading what srvfan has said about the centre spring adjustment, and I’m thinking the reason the back end is breaking loose around corners (even with studs) is because the center shock needs to be backed off. Does this make sense? If I read it right, this would put more pressure on skis and rear of skid?

I do like the fun factor the way this sled is setup right now, as it is controllable all while giviner around corners! Lol
But the fiancé has said the same thing even when we drive at slower speeds that it feels kinda squirly at the back sometimes. I mainly want to set this sled up for her so she has more confidence with it.

And those QS3s...wow, what a shock! Way better than my ltx dx shocks! I didn’t bottom out once over some of the worst 2-3’ moguls on lake crossings or some little feeder trails where groomers can’t get to. Those shocks are definitely broken in now! Just over 2500kms on the sled.

THE BAD:

Near the end of the ride, there was a long straight stretch of trail...and believe me I tried to go faster but it just wouldn’t. 126km/hr and it was pinned to the bar at least 4 times. That’s all I could get out of her. My old 16’ ltx dx did 159km/hr all day long. So I’m not sure what the problem is. I’m not a speed demon and don’t care for top end like do here, but it is nice to know that the sled is capable. Anything I should be checking or looking for? Thanks guys

If the snow was loose it would account for squirrels back end and lower speed. Lightening the center shock will put more pressure on skis and make less traction on the throttle. Try going tighter.
