Different Size Variator

[art]

That does hold true,to get the rpms up. The right combo you get to hold all the way to the top. you got your power band at optimal all the way through. For me and  bat we hit bits of brilliance at the expence of performance through out.Theary again I'll get to it,but thats the way i see it.

yeah, this is really gettin to me....lmao..... VERY AGGREVATING on this end.. my top is pretty much the same but SLOW ASS take off.. i can feel a bad tug(different than b4?) for longer at take off.. it did seem to have an act of slippage 2 times. may not have been but it sure felt like it.....of course i was 2-3mph slower today than yesterday also!    idk, the air i guess. seems to be slow up to 20-25, then a steady climb to 45? LONG piece will get me to 49-51... i wondered if that 1000 would help.. it did seem to feel the tug was in the rear? if that helps/makes any sense...lmao.. why did the zx HAVE to be the smallest,SLOWEST kymco made??         lmao

I think the contra is the key for you(stiffer) than start to down size the weights,Im in the same boat right now you might beat me off the line to 30 mph,than mine comes alive scary fast. Read the link several times it did help me understand (I think)

..carb tuning comes first!!..that was a bit difficult for me to get, until i fully understood plug chops...

....i already had a decent grasp of cvt tuning..

..it's my guilty's claim to fame...

 

..but that post really made it click home......

..i need 5gr rollers in place of my 4.7s i think....

[thebatman]

this wasnt as hard, i dont think, was this dam difficult before the var change......imma sling that dam thing....i cant see the post, phone wont go to it...idk??   oh yeah, checked today, those 3 scoots are still sittin an waiting for me...lmao

[wordslinger]

...yeah, itsa link to a pdf file...

I didn't know that, no place to get on line? I thought  i had my carb  dialed the cvt is telling me were i'm week now,Of corse it was fine till i tinkered with the cvt to beyond my ability    It will get solved if i ever finish any of my many projects. I got a friend that keep showing up with stuff to make matters worse. Got roped into a wood chipper yesterday while trying to put his ch150 back together(he somehow managed to lose the head for it   ) Fun stuff Maybe the geely will fit in the chipper  

[wordslinger]

..dang...i can't keep up with your projects, art...lol...

[art]

Me neither trying to get rid of some completed ones and managed to pick up more.(We will call winter projects) but thats usually when the best deals are! side yard is getting full!   Reminds me got to re up my c.l. posts

Batman- Re-read that link on cvt tuning.  That is a very good article, thanks Art!  I do believe that you need a stiffer contra than what you've been running to solve the "tug/slip" at take-off.  Read the last paragraph of that article.  In going with a stiffer contra you may actually have to go slightly heavier on the rollers to compensate for the additional force from the spring holding the belt lower on the variator face.  I also think that getting a tach will help you with your tuning tremendously!  It is almost a necessity to be able to properly tune the carb as well as the cvt!  After running with a tach now for awhile I don't think I can go back!  With the tach it is very easy to see where the powerband is and where you need to tune the cvt to stay there.  On my particular set-up I run between 7200 - 8200 rpm all the time.  The clutch really locks up at about 7800 revving to about 8000.  Then after I've launched it drops to about 7200 and pulls me the rest of the way through up to a max of about 8600 at full speed when I'm really hauling A$$!!!  I guess the point I'm trying to make is that ideally you need to tune the cvt so the engine stays in the powerband the entire time, from take-off to max speed the engine shouldn't drop out of the powerband.  That is where the slow periods of acceleration are occurring.

thats one thing tho, i have tried stock, 1000,1500.... thought i had a lick when i got the rpms up, but the tug/slip crap mixed with slack ass takeoff..i mean i am only 230lbs., (borderline oem weight limit tho..lmao)not like 375.. whats your take on the heavier variator tho??....

[art]

Ha! I know your asking  shaka but with the mods allot of conventional thinking is no more,do you have the red contra or what is next in your pack. The deal is if you are reving higher overall you got to delay it till your in your prime rpm = the power band. Then tune to your new curve with the weights. For me right now I'm blowing past it so fast cause the tranny slips till it can get cought up than go's like a bat out of hell. I have tried every weight and clutch spring i have,with no real results (I'm running a 12g weight set to counter my miss tuning to get a half assed result) . Because  no matter what I do I'm not able to take full advantage of my new tranny + mods with out stalling it a bit via the next contra spring and untill than no adjustment can be refined with exceptible results ha! I think i'm getting this ,not bad after a pint of whiskey    The weight of your drive face has to be factered in too so may have to lighten up for it also. Simply i have tooo much torque for all to work together,if i do get this O.M.G. It's ganna be fast!!! I don't think 75-80 is out of the question.

[thebatman]

no, i dont have the red contra...i do think that could be to much..(1500 slowed some things down, but helped a bit on top)..i will try the 1000(if you remember last week, the 1500 dam near killed it going on an incline)..i am about to get highly irrate over this crap....$1300 this fkn thing SHOULD HAUL ASS ALL DAY,EVERY DAY..........NOT!!!!!!....   see, im gefting ill with it again..immma end up letting it sit and not fuk wit anything scoot related.....you are losing me, how the hell you go from 5.5 to 12, with thee flick of a switch.? i get more lost these days wit this...

[thebatman]

ok guys, whats up?   ready for a round of dumb ? fellas?....lmao.                      hey art, by the drive face, are you talking about the belt plate in front of the variator, correct??.on the zx, it has the kickstart nut welded on from factory, its steel, fairly heavy,bout var.i wanted one with fins to help cool that side but they dont have one.....this a.m i did notice the tug seems to be borderline slip, seems to tug "deep inside"..maybe shaka will chime in also, hey shaka,i did try your suggestion w/1500 main, 8.5 rollers(no 9s).. that set had garbage takeoff, still had bout the same top, but abslolutely dies going up hills( couldve been this HEAVIER var), so i didnt even bother getting any..i rode it  for 2days(long rides), i didnt like it..i thought i had a roller kit coming but they wrecked a motorcycle that eve. instead, been going to hospital, reason my posts are slack....anybody want to sell a used set of 9s,6s?..lol...i did just put back in the 1000 w/8s, seemed worse so im gonna try the 8.5s

I know it's a little confusing. To brake it down simple The contra is not letting us get to the right rpm to be tuned correctly, at this point for you run the 1500 and start going through your roller set starting at say a 5g  and move up get this as close as possible to your liking. Pay attention to how your carb performs through this also.  The link I posted more or less explains The clutch is a factor but the real gains are in the wieghts and carb tuneing all has to work in harminy to get the best performance!!! If you need some weights  pm me with an address and what you think you need
