Different Size Variator

[thebatman]

THANK YOU BOTH VERY MUCH... a 2000contra on a stock cyl.??..im sure thats way to much for me..you have a bbk& a ppl..lol..  thought the stall came from the flys??

Think of the flys as the very fine tuneing,you have to be in the range before thay are usefull.  Thats where the contra comes in. You have a stock jug but you did the squish and a couple other things so your power band has changed. If it's not the contra you should be able to scream with some weight changes. Almost all your symptoms were identical to mine and no matter what i did could not get it dialed, the reason i have so many weight sets    So don't know where else to turn.(I do have a set of 9.0 and 9.5's if you want to try them out.

she seemed to be slower at take off with the stiffer contra, unless your saying some 10s..lol or some sh**, THEN maybe i could see a difference at all with a 1500 contra(think a 2000 would be wrong, BUT i could be wrong of course)... oh man, yeah, id love to try those rollers..

pm me with an adress and zip i'll send them

Man this is hard to follow!  You guess have so much info and different set-up/trial-error going on!  Batman-  I think that the heavier variator could have some effect on the roller weight, but not much.  The weight of the variator itself doesn't effect the shifting, but probably more the engine and it's ability to rev to the powerband quickly.  You also have all of this info about how it's slower taking off and what not.  Nothing really about the engine rpms.  What I'm getting at is you need to pay attention to the engine more than how fast it accelerates.  When you are taking off slow is it because the engine is above or below the powerband?  Are you revving the crap out of the engine and going nowhere fast?  Or is the engine below the powerband and struggling to rev up?  If the rollers are too light and/or contra too stiff you will stay in the "easy" gear longer and overrev the engine.  If the rollers are too heavy and/or the contra too weak you will shift into a harder gear before you engine can rev up into the powerband.

Ha!  I hear ya shaka I think the veriater weight was not in question it was the drive face. I had swapped to an aluminium and it threw any progess i had out the window.  A reminder don't change to many things at once!!!

..on my a50..i replaced my oem drive face with an aluminum NCY.....(MUCH lighter in weight)..and had to increase my roller weights to 6 gr from 4.7 ....

Got ya!  I'm not aware of an aluminum outer pulley face for the ZX.  It has the starter teeth around the edge.  May be able to adapt one to fit, but you'd lose your electric start.  Not an issue for me though, been kickstarting for over a year now!  I don't think that steel pulley face will have much of an effect on the variator.  I wouldn't know though, I'm still running the stock one as well as the stock torque driver and clutch bell.

Good advice on not changing too many things at once though!

There's some real world evidence!  I never really thought about it.

..itsa true story...

..but i'm running the stock face now...

..didn't like the 'luminum one...it made my belt ride against my starter bendix...

..had a taller profile...

[thebatman]

your still running the stock var shaka??? wow, figured youd changed that long ago...lol......... i am always below the powerband....now it hits it sooner than before but i have tug and slow ass take off, (below band), then a decent climb with good rpms then levels out..seems to be in power band more now since the 2000 flys installed with stock contra and 7.5...                                                              awesome,art,thanks man.....woooo hoooooo....

Ditto thought i knew what i was doing. Ordered the 9.5g dr pulley set and didn't work at all with the lighter drive face. Now running a 12g set and could go more.

I am running a Malossi Variator, but you still have to use the stock outer pulley face with the starter teeth on it.  Keep in mind that your fly springs don't effect any of your shifting, just when the clutch engages!  You can leave those out of the equation until you get your shifting sorted.  If you are below the powerband then you need lighter rollers and/or stiffer contra.  You should not need a 2000 contra.  If I were you I would start with the 1000 contra and tune the rollers from there.  Put in your lightest rollers and see if you are still below the power band.  When you're too light you'll know it!  You will instantly rev to max rpm and not go anywhere fast!  You'll be creeping down the road doing 15 mph, sounding like you're doing 70 mph!

 This drive face will work with the people 2t and the a50 and probably some others, With a starter gear, I did have to sacrifice the fan,but the aluminium seems to disapate the heat well and my clutch is vented.  It runs a bit taller on the ramp for a little more top. I might be able to use the electric start with this also on the people 2t Havn't put it back in yet (it did turn it over no problem). Was worried about the belt rub.  http://www.provoscooter.com/scooters/ruima-racing-variator-139qmb.html

That's pretty cool!  I've never seen one with the starter teeth.  Says it fits the Agility.

 Slinger- did we determine if yours uses the same variator as my ZX?
