that problem is unknown to me, but could be possible. Maybe with the new batch of malossi variators the bronze bus ain’t good or something. But the polini speedcontrol ain’t without problems either, so.
anyway @giuseppe,
Remove the vario-plate (where you bolt the nut on) and see if the vario-housing moves (without the belt).
Let us know!
Hi Tnerul
yes i understand exactly what you mean on the subject.
i think the problem will lye with the variator for sure not variating at all which is what seems to be the case with mine.
I would be curious to find out from someone what the solution is – maybe to buy a new one ?
If i find everything is fitted correctly which i’m sure it is then i have no option really but to get another one.will do Niek that was i was going to check that it slides across the bronze bus correctly.
thanks

GiuseppeYOu should ask, or wait for a reply from one of the experts here on the forum 🙂
Because, as i had already noticed, it’s not the first time i hear this problem about the MaMultiVarHi Guys
I took the variator off tonight and all seems to be well with the fitting, with the malossi belt off it also slides across the crank arm nicely.When i put the belt back on then it doesn’t variate.
The clutch disks are also fine as they are quite tough to open so i can’t see the problem is there, multivar definitely not working as it’s not opening up at all i’m at a loss really.
HELP anyone.

Giuseppetry lifting the rear wheel & then start revving (not for too long, rear-clutch could explode if you revving too long). Just check if the variator variates. if so, the problem lies within your rolls.
Hi Niek
i have had it on the stand revving it but still nothing and i rode it for a bit no change.
it gives me good take off speed but that’s it doesn’t variate.
what do you think i should get heavier rollers ? i thought that 5.1g’s would be fine on a 75cc.
i didn’t put the 4.7g ones on because i thought they were too light.
PLEASE ADVISE so that i can order them in.
do you think that having the malossi yellow clutch springs are too stiff and casuing problems here ?
cheers
GiuseppeI’d try some heavier ones, yes. Around 6-7 grams (polini has a nice test kit). Yellow springs shouldn’t give problems on your setup.
Stronger clutch springs(the big pressure spring) need weightier rolls.
@tonni here on the forum, has exactly the same setup as yours, except for the exhaust(Gianelli mega), and he uses 5,3 grams rolls. But indeed, what @edjuh says. Try some heavier ones. You have excluded the problems with the variatorhousing on the crankshaft + the rear clutch. So, it should be the rolls yeah.
Hi Guys
Just to update on the matter.
I replaced the rollers with heavier weights last night and even though the engine sounds better shall we say the vario still does not open, i have tried all sorts last night.
Took the clutch off checked everything all is good, cleaned up the bronze bus inside the clutch and lightly oiled it to make sure the tension springs moves freely, put everything back together and still the vario doesn’t open at all.
I even changed the yellow springs the 3×3 for the stock ones just in case.
Clutch disks all seem to be good as i can just about move them by hand. even putting a screw driver in them and they open up nicely once with the belt on and on the bike.
I am stumped to say the least and apart from trying another vario i really don’t know what else to do ? but that involves spending more money.
Would anyone have a good used working polini / malossi to sell at a good price and send to the UK, just a thought.
Thaks to all
GiuseppeI would suggest to make some pictures and post them, perhaps we can see something wrong on the pictures.
no problem.
I was intending on taking some pictures this weekend and then i will post them up for you to look at.
I take it the black vario front plate can only go on one way can’t it ? in other words i don’t think you can fit it wrong.
Do those red things have to be installed, i got them on now but i suppose can try without if possible ?
thanks
Giuseppeyou should use the red “triangles” yeah, those are used to guide the black vario plate.
Those would only be a pain in the ass when the vario-plate doesn’t variate back. Then those red “Triangles” are to narrow;). but that’s not the problem in this case.
Maybe a silly suggestion, but you haven’t installed the plastic ring onto the variator have you? I’m talking about the thinner ring(not the distance ring that goes between flywheel and variator), which is a limiter.
Ok Niek i got the red triangles on anyway but just thought i would check.
Hi Edjuh no i never used the plastic bit as i was told was not necessary.
I will try and use a heavier roller combination tonight and see how it goes.
i’m gonna try 6.6’s and 7.6’s tonight as last night i only tried the 6.1’s.
Did you guys have these issues also when putting on a vario transmission, pain in the arse this is anyway.
thanks again guys
GiuseppeThe only common problem (with multivars) is the belt slip, which can be helped by grinding a little of the ‘bus/hub/round thing’ where the disc attaches so that the gap is smaller when idling.
