That's cool, it come nice and new, or did you paint it? Looks brand new!

Thats Technigas RS? How is that? It's the only pipe I"ll give up my Chrome NextR for.

Boy howdy that's sexy. I've dreamt of having one that looks that nice...

This is the strongest S9 I've ever owned...And nina was my baby, back in the day...the big pipe is awesome...

Thanx Trie...
I searched for a red one for a long time...Couldn't pass her up!!

yeah, gearbox is OEM...cvt is modded a bit tho...

that's cool, I thought maybe 10500rev's. you really got CVT figured out. Tries is working to duplicate your ride, maybe me too.

...the absolute key is tuning to whatever pipe you're running...it wants a certain engine rpm as it's powerband..
..gotta tune carb to pipe, then tune cvt to keep engine rpms within that powerband...until you reach top end...
..cant do it without replacing the oem driven pulley...

..the common denominators to every one of my best S9 cvt setups are a Malossi multivar variator and boss, with oem drive face..Dr Pulley sliders, at whatever weights to keep rpms at PB uphill...Gates premium 732x18.5x28 drive belt..OEM KYMCO Agility 50 driven pulley and torque driver, with a Malossi Blue 1500 contra spring...Stage 6 MKII clutch...very adjustable..with a50 bell...Have to adjust slider weights and MKII spring tension to keep scoot in pb uphill and at take-off...
easy-peasy!

I have Malossi variator and I guess the boss that comes with it is what you use? What is "PB" uphill? Why do you use Agility 50 driven pulley, larger OD? The belt is a little wider than OEM, is it longer or shorter?
I really like the Malossi variator, added approx 5mph after install because larger OD I think? Cheers
-
Pb is power band. The agility 50, or a50 pulley is like the malossi, but without the different grooves or price tag. The belt is 3mm longer, I believe. And the rear pulley od only affects the takeoff, or low gear. Where the belt sits down into it would affect the top speed. The lack of that bead in the center may let the belt deeper.

And I believe that the weld, bead, bump thing, that's on the front half of the rear pulley, right? What I call the torque driver? What way is the stock back half of the rear pulley, or driven pulley, restricted or in any way less than the same as the a50 driven pulley? I'm trying to avoid ordering an exact part when I have ordered what I think is already the piece that needs replaced...

..the hump at the bottom of the s9 oem driven pulley is by design, a speed restriction.
In my experience, the oem KYMCO Agility 50 driven pulley AND torque driver..(which have not the hump...)
performs very well, if ...you have a stage 6 MKII, (adjustable) clutch AND a Malossi blue 1500 contra...

don't need the malossi grooves..and yes, getting your belt as deep as possible into your driven pulley is ideal... especially for balanced performance and oh, yeah....top speeds.... :)

tha A50 pulleys are smooth, all the way to the bottom of their face..OEM super9 driven pulleys have a "hump" at the inner diameter, which keeps your drive belt from driving all the way down into the pulley..
...restricts top speed, causes belt slippage, which in turn causes premature drive belt wear...
-
..pretty much ALL Kymco 50 cvt parts have same physical dimensions.
.....except for the super fever...lol..
-
Ahhh, the straight grooves! Maybe I should've saved 20 bucks and gotten the agility setup. Damn.
My agility 4t has the same exact rear pulley as the s9. So I didn't think of that.

64mph at 9100 revs, you got it figured out IMO. I am running the Malossi torque driver and it has the weld machined off, is smooth. So far, I don't think it's given me any additional top speed, so maybe I need to do some more testing. Cheers
-
That agility it's sexy! Mine just has a look to it like a very butch woman. Kinda thick and stout lol. It's a 2009.

Yeah, and if that's real works 60 plus at a little over 9k then I could be easily turn more at the 10.5k that mine's pleased to run at. I was always told that I should be faster. I didn't take the weld into account. Since every torque driver I've seen had one I thought it was on all of them.

The famous shoulder on the Malossi torque driver is there because the weld is machined off on the belt side. Would be cool if I had the right set-up with driven pulley, just need to tune it some more to get belt a little lower? Maybe all I need is some heavy sliders to try? Has anyone noticed the weld getting shinned up from the belt rubbing on it?
Actually, I am OK with turning 10,500 for short bursts to get to 60 plus mph, but wouldn't want to cruise at 10,500. Mine is pretty sweet as is, but my scooter would be bringing up the rear in a top speed competition lols. Cheers
-
Well, I've got the 732 length belt on the way. That will give me the extra bit to ride all the way down, and up the oversized variator.
Does your belt make it up the variator, chaz? On my malossi variator it did, until I removed the back plate on the delta allowing the pulley to open completely. Then I had some space.

Thanx chaz...and she jumps off the line pretty quick too...
..That's not really a machined weld, on the malossi..It's just made smooth..
..what size drive belt are you running? ..I ask because if you remove that "restriction", you'll need a longer than OEM belt...

this is kymmi on the day she left me....she went to Asheville, actually...
-
..with a restricted driven pulley, the drive belt slips in the variator at top end, which increases rpms and creates a loss of torque, due to the engine revving higher than the pipe's powerband...

..kymmi all lit up...

I am still running the Kymco OEM clutch, so don't have black plate to remove (I think Delta is your clutch?) Yes, seems belt comes up pretty close to the top of the Malossi variator. I am running the OEM belt too, has approx 8000kms on it, so width may be hurting my top speed a little too.
Next project, install Malossi torque driver on my other S9. I will be looking at it closely for how low the belt can go on the driven side. Lots of trade-offs, if you make the belt shorter to get it lower on the driven side, it will not get as high on the variator? Like word has done, have to get everything working together: sliders, belt, torque spring, all have to be balanced to get belt high on variator side, low on the driven pulley side for max top speed. I don't think I am there yet, but will look at CVT again, looking at some different angles.
I am thinking word's engine is making good HP too. I don't know, but think these engines are probably making max HP/ torque something a little less than 9000 revs, so word is right there. Word, tell us more about your engine. Cheers

I think a lot of it was in his thread I shared to you, chaz. Unless he did more since, which is quite possible.
Yeah, the delta has that wretched back plate. Mine needs a rebuild or something. It's just in a box right now. The stock clutch is very nice. I know that I'm running close to high power right now, which is why I was wanting a performance clutch, and I wanted wheelies at one point. I'm over the wheelies at the moment, but I kinda like to hnoave a nice list of parts to rattle off. Even though the wiser tuner would be able to duplicate performance of the big names with the already sturdy Kymco oem things.
I'll be satisfied once I get this torque driver in and set up. I think I'll have some good things to report

Hey! I blame several things, including early engaging clutch and weighing a ton...

There is a little S turn/ chicane on concrete (the best/ safest traction I know of) I go thru often that gives a really cool sensation. Start off at stop sign, give is WOT and veer left a ways and build up some speed, then turn right, front end gets light. Ever watch MotoGP?, I know silly, but it's like that a little, scooter leaning to right, scooter turning to the right, but front wheel turned out left, feels really cool, I would take it over a wheelie any day.
I read thread all 29 pages on my computer, lots of good info. I probably won't change clutch or belt, just too much work/ expense for me. There is law "law of diminishing returns" that sets in when you get close to optimum. Basically, you have to do a lot of work/ spend a lot of $'s to get a small additional improvement. But you never know, I have done way more than I ever intended to do, and having a great time. Cheers
