YES, a performance variator that dosen't require an extreme setup to function properly!
The Mallossi Varioplus is the answer for those who want to upgrade from the stock unit, but don't want to go the rought of a full performance transmission setup.
I purchased mine from Treats HQ for $66 or so dollers. Basically the Varioplus is a replacement performance moving variator plate. Its made from aluminum with a steel sleeve pressed into the center sliding section. Instead of 3 balls the Vario plus uses 6 rollers. 3 different weight sets come with the unit. There are nine different weight configurations (if the math is right) since you don't have to use all the weights, as long as the plate stays balanced, however mixing the different weights could open up even more levels of tuning i suppose.
So the con of this thing is that it requires complete variator removal and disassembly to install, ok not so bad one time right, well it also requires complete variator removal and disassembly to switch the weights, or better put, to tune.
Luckily for anyone reading this who wants to purchase this unit I have done some leg work for you and give a few weight recomendations at the end.
Installation; here is a wiki page about cracking the variator, use the manuel to remove it from the bike.
Once the variator is opened you can install the varioplus, it fits right were the stock variating plate normally goes. it also comes with some plastic sleeves that need to be installed over the variator pins coming off the starter clutch assembly so the clutch drum will have to removed to do so.
reinstalling the clutch drum can be tricky since the plastic sleeves make the pins wider and if they are bent a little can make reassembly a bitch, make sure you tighten it down all evenly (4 screws hold it on). The Varioplus comes with a set of allen key replacement screws for this, but I opted to use the original motobecane ones that are slightly shorter and fit better.
Other than the screws, assembly went smoothly, remember to grease up the weights!
I also shaved down the center of the varioplus plate so that it can move further giving me a higher final gear.
As for the weights I used all 6 of the second heaviest set (unlabeled) and it seems to be great, it was the perfect weight, for my setup, i got hella lucky i guess.
If I were running a stock setup completely i'd run all of the heaviest weights and hope its enough. The really cool thing is that this could be used with an AV10 monster motor with the huge amount in weight range on the lighter side, but tuning could be a nightmare!!
My setup for reference is:
Av7 portmatched to a mallossi 62cc kit
Ninja G3 pipe
16:16 dellorto carb with 80 jet
stock large bendy intake
old 4l320 belt
mag scrapper rims
stock 50v gearing
and the mallossi varioplus (all 6 of the 2nd heaviest weights)
The unit looks stock witch is great since i hate the performance variator blue anodized look.
As for performance, the bike rips out of the hole much better, and keeps that torque all the way thru a now completely seemless power band, the revs are higher at lower speeds so it really takes off well. A scooter rider on a new 150cc bike said he was amazed it could "zip along" so well at a stop light, seriously he was not much faster off the line, i'll take the compliment.
The top speed is slightly better due to the shaving of the variator, and hill power is great it will climb even the steepest hills in San Francisco and right with traffic or faster.
Overall its a great buy and works well with the 62 mallossi kit and a pipe carb AV7 setup, it will surely out accelerate and maybe out top alot of Puch polinis especially with some engine portwork and a larger intake...etc., but that's not the point of this setup, its a solid, quick, kitted motobecane, what else can you ask for.
I got lucky on the tuning, so all i can see from it are pros really, $60 odd dollars for ripping hill power, le sick!
La resistance 4 life!
