Zuma Tecnomoto Variator Mod (Part II)

[mikhail masevich]

I have a roler weight question I have a stock set up I changed lighter roller weights and and looks like the belt or clutch is slipping but the scooter is not going

[XPS1210]

if your running to light of weights the variator will not spread as it is supposed to and will allow the variator to spin and the belt to not....

If it was running fine before go back to the old weights... if not then try a mix of the weights you had and the new ones... do 3 and 3.... see if that works...

[mikhail masevich]

what should I do will a new clutch work. Polini 2 shoe clutch. What should I do to make it grab the light rollers

[XPS1210]

well if the belt is slipping... then you need to put the stock rollers back if that was the only difference in the scooter...

The clutch, if it's slipping you need to change the springs....

[hungff77]

roller weight has to do with the exhaust pipe. If you are only using stock exhaust, use the stock roller weight. I think if your switch the torque spring for the stock to a heavier one, you will suffer even more. The stock roller is ...I think 6.5g. The medium weight from the tecnomoto vario is about 6g.

roller weight has to do with the exhaust pipe. If you are only using stock exhaust, use the stock roller weightI don't totaly agree with you. Tuning to hills, rider weight, and acceleration needs different rollers


The Stock roller weights on the Zuma are 6.5g

The techno vari kit comes with 3 different sets of roller weights

The silver ones = 3.5 g
The Black ones = 5.5 g
The brass ones = 9 g

these weights are naked... add 1.7 grams for the plastic caps...

[XPS1210]

however.....




If you are a larger person you could benefit from lighter rollers in the stock variator...


So.... It's all a matter of your riding situations and conditions...



The flip of that... the stock set up is "universal" so it will work for the most people without having to do any tuning!

exactly

[hungff77]

But exhaust pipe change the power band of the cylinder, there it need to change the roller weight to adjust to it. also, it is a big drop from 6.5 to 3.5. Of course, weight, acceleration and hills do factor, but it is a balance act of all. Like all factors are related to each other, so is the torque spring, clutch spring, roller weight, and even the belt width. But 3g changes makes a big different.

i would like to know if grease would help the rollers work better just a question never done it and won't unless it's good to do :cool:

[XPS1210]

For sure, I'd say no Grease....

2 reasons....

1st... Other tranny parts being contaminated with it...

2nd... I think it would hinder the rollers from working...
They don't "spin" in there.... what the rollers do is move out with more RPM's due to the weight.... basically if you stand on a marry-go-round... The old kind I remember as a kid riding (the ones you push)....

anyway, if you stand just off center at low rpms it's easy to stand straight and not fall out.... the faster you got the more you were likely to fall "out" towards the outside of the marry-go-round...

Now as you moved out on the deck of it... and the speed was increased, the more you felt like you would fall out... In fact you could hang by your legs on the rails and be horizontal with the ride...

Now with that being said... if you were sitting in a marry-go-round with jello on top... it'd be harder to "fall out"...

With THAT being said... the grease wouldn't help as the rollers don't spin, they do just what they are called they "ROLL" and with the added G-force from the RPM's cause the pulley to spread...

Now if that all makes since... You'll understand why the grease would do nothing but make a mess and possibly cause other problems...

[Zuma88]

that is the funnest explination for that i ever herd, but it is correct.

some young people 18-25year olds had some bungE coreds like 10 and rapted it around one of those and stood in the mid a pulled it and the kid in the middel flew off

[BlitzK]

Hrrm... If you look in my "scooter garage" thing you'll see pics I took... My KRD has these "tabs" as well...

my 0-10mph SUCKS

Should I cut these tabs off?

[ScooterJim]

No Grease!

[thracing]

Mine did too. I ground the tabs off and holy cow, off bottom throttle response is amazing.

I use a bench grinder to remove the tabs and my porting tool to clean-up the rought edges. It's about a 10 minute job and well worth the outcome.

[Zuma_Man]

I will grind off my tabs and put it in with my stage 1 kit, though I wont really know too much of a difference only because my scooter is going from stock to stage 1 with pipe, and cutting these tabs off. who knows, I will know if it takes off harder like a bat out of H3LL :) Wish me luck.

[XPS1210]

only take 1/2 of the tabs off not the whole tab... or your V bushings might have problems... if you already took them all off, use the stock variator vbushings as they are larger then the technomoto ones

[zuma ned]

does anyone know if the malossi multivar 2000 has these tabs?

[XPS1210]

the tabs are to allow the variator to move out and not have problems with the Vbushings coming off... Now most scooters won't have this issue due to the thing not spinning hard enough to have this happen

[Zuma_Man]

I cut my tabs down, all except for 1mm, and sanded them smooth with a grind stone. the stock tabs wont fit, I tried, they're much too large, maybe I can try ordering some aftermarket ones from provo? with how slow the scoot is now, I can only imagine what it would have been like had I not cut away most of it.

[XPS1210]

I had ordered extra ones when I bought my original stage 2 kit, there were about 3 times as big as the tiny ones that came with the variator... and worked perfectly...

[Zuma_Man]

You've installed the tecno vari before right? Its almost like the tabs that came with it, are an improper but perfect fit as compared the stock ones, the ones in the kit could afford to be a little bigger and thicker, main reason being why I didn't cut the tabs off flush, and left 1mm, so the bushings wouldn't have a big issue or even fall off, though with tecnomoto putting extra long tabs to restrict them, for all I know they probably had CRAP vee bushings to begin with, I will order some aftermarket vee bushings, however I dont think at this point it will make as much a difference, I just hope that someone who installed a stage 1 kit, to reply to my thread as to why I am able to run faster than my acceleration.

[XPS1210]

To be honest, IMO the technomoto is simply a cheap variator... and they went as cheap as possible... on everything...

but... can't say for sure... those "tiny" V bushings... are that exactly tiny...

here is my compairison.

v <--- technomoto \\\/// <--- the replacement ones \\// <-- the stock ones....

[Zuma_Man]

does that mean you think the tecnomoto's are bigger than the stock ones? i find it the opposite, another thing, do all the tecnomoto kits come in spanish? All my instructions, kit, everything was in spanish, and i dont read or speak spanish, was just wondering if that was the case, or because I lived in new mexico I recieved a spanish kit...

[XPS1210]

nope as followed from small to largest V bushings...

technomoto's (tiny little "v") the stock ones (better "\\//" in size)... the replacement ones I got from provo (biggest "\\\///" in size) all relative in how your monitor looks but the "v" is showing that the technomoto ones are tiny and just barely hold the variator to the pulley face... the stock are better and the replacement ones are MUST better

[Zuma_Man]

I tried putting the stock ones, they wont fit, maybe I'll get some other ones from provo, but I want to get my scoot, for the love of god, at least to 45mph

[just me]

Well until you get the other "V" bushings from provo dont cut off any of the tabs. I did that and had all sorts of problems. The bushings are thinner and more brittle than the aftermarket ones. If you cut off the tabs without the new bushings your vari will come out too far and lock in the out position cause your bushings will fall off the tabs. Need to be sure to have the other bushings "first".

[XPS1210]

that's why I always tell everyone to only cut 1/2 of the tab off...

[pinkymingeo]

The Technomoto tabs aren't much different from those on a Multivar. The Multivar, though, has a slightly shorter hub and uses a 2mm washer for clearance from the starter clutch.

[Zuma-Zuma]

Can't you use your stock vario??

[psychoscoot]

hey erich,so am i be going through this too of modifying the varry?co'z i just ordered one w/ a kevlar belt for my o3 zuma

[XPS1210]

No one said anything that you HAVE to modify your variator... So... NO, unless you but on it...

besides, erich isn't much for surfing the forums... and you should contac him directly if you have questions... or one of the moderators...

[Lennox]

the last Techno I got from Erich was "pre-modded"

[psychoscoot]

i just got mine too today and i was reading about grinding the varry post, lookin at it the varry post doesnt really stiks out the varry wall but when you run your fingers to it you could feel that it does sticks out about 1 mm,so do you think i still should grind it and smooth it out till the varry wall?

[XPS1210]

leave it alone.... it's not needed to make it work the way it comes.
