hi guys,
does anybody know if the multivar malossi variator M519988 could be fitted manteining the electric start or should it be removed to fix this variator???
the scooter is a kymco super 9 ac.
how much top speed did you gain with this improvement (only variator) ?
i already have an airsal 70cc ac, 24mm carb, tecnigas trek, long primary gears malossi, dayco belt 18 x 743 mm, a very good torque but i'm stocked to 90km/h top speed at around 9300rpm...
i start to think that the point is the original cvt assembly, does anybody tried multivar + maybe an oversized torque control and longer belt on kymco super 9?
thankssss in advance for the help :)

anybody that tryed multivar on kymco super 9 :( ?

I had the Malossi variator on my S9. It fits without modification to electric start or case.
Using an aftermarket will not increase your top speed.
You should be getting more than 9300 rpm out of your Airsal. Did your exhaust have a restriction, and has it been removed?

actually i have the original variator kymco with 5.5gr rollers.
no restriction on cdi neither on tecnigas or variator :(
do you think to try some lighter rollers?
-
Those rollers seem pretty light for a Kymco. Did you change them out?
Not sure, but I recall 8 or 9gm rollers are stock. I have 9gm in my Super 9.

yes, i replaced them, tecnigas with airsal sport 70cc should have powerband between 8500 and 9000rpm, if i put 7gr or more i can't be near the powerband during the shifting

I've got the Airsal in mine also. With lighter rollers the rpms are too high when cruising - pegs the tach upon takeoff then around 9500 cruising -way too high. Going to the 9 gm settled it down. I am running a Polini variator, so that may make some difference. Top speed is around 60/62 mph.
That belt you have - is it stock length? Or did you attempt to go to a different size for some reason?
Nothing better than stock belts IMO.
-
actually i have a DAYCO BELT 8134,18 x 743 mm,
probably should give a try to an OEM one to see if there will be some improvements.
regarding the rollers i tryed everything from 5.5 to 7gr, when are heavier i get a bad take off so till now the 5.5 seems to me the best compromise
(anyway i double checked on the variator and the belt arrive with no problems at full travel when WOT)

Final thought - have you installed stronger clutch springs? The powerband in the aftermarket exhaust necessitates that you do so.
Otherwise, you engage the drive train at too low rpm when engine power is low.
Light rollers compensate for this by increasing the engine power, but results in high rpm at take off and higher rpms at cruising.
It is a balancing act between roller weight and spring strength.

I already have blue malossi springs engaging at about 4000rpm and corretly balanced with contra spring.
my only idea would be to give OE belt a try to check for any improvement in top speed, at the moment i'm locked to 90km/h at about 9300rpm...
