Hi, Im gona change my variator to a Malossi Multivar with 5.1 gram rollers.
I have gotten into the variator, but cant seem to open the main nut..
How do I open the main nut on the Agility 4t 50?
Thanks
-
..i now use a 19.2 volt cordless impact wrench, however for years i used these 11-R clamps to hold the drive face, while i attacked the nut with a 17mm, 1/2" drive socket and ratchet...
-
Same as Word, i use an impact wrench, couldnt get it off any other way tho i did try about 2-3 other methods. Its much easier using the impact wrench, they are not much more expensive than the special variator removal tools and you can also use it on your rear pulley too.
-
I purchased a 12v brand new cougar impact wrench from eBay for 19 pounds with free delivery and it also comes with 4 impact sockets including a 17mm one, to power it just connect to your car battery or other 12v power source, with it being a impact wrench there should be no need to lock the variator to loosen the nut. If the cougar one is not available there are RAC ones available on eBay but a little dearer just search on ebay for RAC 12v impact.
-
Okey, here is my next task. I need to change the contra spring..
Where do I get the tool for that?
-
@wordslinger- so you just line the teeth up and put the clamp on then hold it with your hand while with the other you loosen the nut?
-
I use my torque wrench to remove the bell cover nut then remove the whole rear pulley. Then i slip an oil filter removal tool (£8) over the clutch, making sure i dont damage the clutch pads. This holds the clutch then i use a large adustable spanner to loosen the big nut that hold the clutch on to the rear pulley.
Make sure the filter tool is the metal band type, not nylon and def not the chain type. Mine is like this,

Remember to put some threadlock on the threads for the variator and clutch when your refitting the nuts, stops them working loose.
-
..yup..just try to align arms 180 degrees apart, for better grip..
..i usually lodge the handle against my boot as i'm pulling up counterclockwise on the ratchet handle...
..if it's never been loosened before, the first time might be a bit tight...
..if it tends to slip, turn the 11r around the opposite way

So, I just put together everything (the variator and clutch) for the 2nd time.. and I was missing the plasitic bit that came with the variator, so it didnt go forward.. only a wierd noise.. Where do the plastic bit go?
Also I would like to know how the rollers are supposed to be.. Been trying to look it up, but cant find how.. Right now I have then with the Malossi logo facing forward..
Thanks

Do not run it without the plastic bits on the variator, it will wreck it in no time. You can buy spare ones if you lost yours, just look for variator guides or ramp plate guides and you should find them. I saw some new ones on ebay last week for under £4.
Most rollers can go in either way round, some have a slightly thicker end tho that are meant to go in one way.
-
Okey thanks, I still have the plastic ring that I got with it.. But I dont know where it goes.. Didnt find the right drawing in the manual or internet..
-
Please answer
-
that plastic ring snaps on the outside of the plate just befor you put the bold back on. make sure all parts are there even theam 3 little v like things with out you well find out soon to soon.
-
..you do not use the plastic ring that comes with the multivar...
..frow it away!!!!

..well, that's not good at all..
..can you post some pics, for something is amiss...
-
..malossi rollers dont matter which way they roll, but i like to put the white letters to the right, on top...
..doesnt wear whites off as quick..lol..
..should look something like this...
..click on pic for larger view..
-
...ramp plate, and the afore-mentioned plastic pieces should look like this...
-
...assembled like this...
-
...cvt, minus drive face, fan, etc., should look like this..
-
..oh, here's one complete...
-
...don't let the location of the starter bendix throw you off....all these cvt's work in the same way...
-
I dont understand what I could have done wrong.. I cant think of anything except the plastic ring.. So depressing.. lol
Is there any videos on how to install the variator?
-
And how do I start it with the panel off? To see whats wrong..
-
In this thread the guy used the plastic ring successfully on his Agility 125..

Im so confused..
-
I just tried to put it together again for the 4th time, and when I gave it trottle it makes a really wierd sound and slowly moves forward. I think I ruined the whole f***ing sh** now. Im f***ing sick of this, I hae done everything right and nothing works.

1st of all dont panic, it prob just a minor issue or fault somewhere in your reassembly.
Did you fit all the rollers back in correctly?
Did you make sure you torqued up the variator nut properly so it cant come loose?
As for the plastic washer thing, i wrongly thought u meant the ramp plate guides not a washer thing. I cant think why you would need the washer so if you fitted that then maybe try without it?
Is the smooth boss length the exact same length as your old one? Exact same? Of its shorter by even 0.5-1mm then you need a washer under the variator nut to space it.
I have a race variator too but not Malossi and mine had no spacer or washer other than the washer that was already under my variator nut?
I doubt you have done anything terminal or bad so try not to worry, we've all been there in the past when we were learning to work on our own scoots.
-
Thanks man, I was really pissed there for a second..
But I think I fixed it now :)
Takes some time for the battery to charge though..
Thanks for the help,
Means alot that you guys helped me!
-
What was wrong do you think?
We all had that "Why the f*** did i not just leave it alone" or "Oh crap now ive broken it for sure" moments, most of them are minor mistakes or have a simple solution so now i tend to just leave it, walk away, have a coffee/beer and a smoke and calm down. After 10-15 mins things seem a whole lot better ;D
We live and learn every day bro :)
Keep us posted how you get on once you can test it. We've all got your back, we CAN fix it if it breaks :)
-
Thanks alot man!
Gona get back if something happens :)
-
I had one of those holy sh** moments last night, big time. The trick is not to wait too much longer than fifteen or 30 mins or overnight, like I did, before figuring out the extent of damage. Then you start to take it out on the girlfriend, wife, kids, and dog hahaha. People can usually tell from my demeanor how well tinkering with my scooter went. If I went well I'll buy ya a beer, if not I will I will throw a beer at your face. ;D
-
Hahah, true..

Yup :D
If i come in from the garage whistling or singing then talk to me, if i come in mumbling or cursing then dont. Its the unwritten rule in my house lol.
Nothing worse than when things dont go as easy as you thought they would and it puts you on a downer and you hate the world (cos obviously its all their fault) but when things go well or you get to the bottom of an annoying problem and fix it then things are fantastic and you love everyone :D
-
Thats so true my friend :P
-
Ok, so here is my current "thing"/problem. When I start it it chokes if i give it some throttle.. Have to wait for a while to slowly give it the throttle neccesary to move.. Then its usually ok.. Could it be that it needs a bigger jet?
-
You didnt touch the carb at all did you? Just did the variator?
When you say it chokes, do you mean like its going to stall?
Mine does that if its real wet or cold sometimes if i dont let it warm up before i ride it. In that weathet i normally turn on my scoot on the stand and then leave it to run while i get my gear on, after a few mins the revs die down when the auto-choke goes off and im good to go. On days like that if i dont warm it up 1st it wont run as well and even stalls or cuts out at traffic lights etc sometimes, if i let it warm up tho its fine.
What size jet is in it now? Should be 82 if its de-restricted but still on the stock air filter. Even if its only got an 80 jet in i wouldnt expect amy idle issues.
Does it idle ok and its only when you give it some throttle it "chokes"? Once its warmed up and running is it ok or does it always feel like its choking?
-
I did touch the carb, it already had an 82 jet for some reason..
Its fine, just takes some time to get it revved up..

After opening the carb it can take a few seconds of cranking to start it up, you normally have to let it keep going till the float bowl fills up with fuel again. 1st time i did my jet i thought i had broken something cos it took ages to start up compared to usual.
So is it all good now? Did you take it for a test run, if you did how did it feel, improved?
-
Took it for a long ride today, and the speed is definantly improved.. I tried to "floor it" on a looong downhill, and got it up to 90 kp/h... In steep uphills though, about 40 kp/h..
And also I felt that it was a bit shaky and made some wierd noises some times.
Other than that, its all good :)
-
Mine made some weird vibrations and rattles at 1st when i de-restricted and tuned it but it settled down after running in a few days. Just keep an eye on it, if it doesnt go away or gets worse you may need to investigate.
For better uphill speed fit a stiffer contra/torque spring in the rear pulley, stock is rated about 850rpm i think so try a 1000rpm or 1500rpm spring. That'll shift the gearing, keeping it in higher gears longer and downshift sooner when the rpms drop on hills. I do most hills at 30-40mph on a 1500rpm one, keeps it pulling well all the way up. :)
-
..gotta let things seat, palli...
..whirring, and harmonics will happen...
..the more you mod, the more you gonna hear unfamiliar sounds..
..sounds to me like you got it goin' on!!!
-

Police sirens are the worst lol. :D

+1 streido
..i hadda state trooper turn around and follow me today....
..love those dual disc brakes!!!
-
Damned coppers ruin everything. >:(
.......except a good car chase :D
-
Hahah, did the cop catch you?? lol
Anyway, I did get a 1000 rpm contra spring with my Malossi variator set..
And its in the clutch..
-
he followed me for a mile or so, just to fuk with me...
-
I would run it for a bit and enjoy it then maybe later you can try a 1500rpm torque spring if you need a little better hill speeds. The 1000rpm does help out , i ran one for about 6months on 5.5g rollers but after trying a 1500rpm i found it suited me better, especially in the 5.1g rollers, my revs now stay up mostly in the 6000-7000rpm range when i ride.
It just takes time, patience and trial and error till you find the best setup that suits you and your terrain.
Its only taken me a year so far of tinkering and testing, but i think im almost at my perfect set up now.......just need the ooen filter dialed in next and that me finished for a while on tuning, it should be at its peak for me then.
