Finally went for a ride today, an embarrasing 46 mph.
I posted previously that my setup included a 2k center spring. Well, shipping at VT had some problems so my spring won't get shipped till tuesday. I used a 1k center spring that i had for now. What i found is i'd get to 45 mph when variator kicked in and then i was stuck there. Burnt Toast was right again when he told me to get the 1.5-2k spring now or pay for it later. Looks like i need a later shift so i can hit powerband. I need a new belt too, it's pretty floppy and probably stretched. I'm running a 55 pilot and 135 main for now. Temps seem stable. I'll update when my spring gets here and belt gets replaced.

Rollers
Greetings:
What weights in the OKO? Did the engine sound like it couldn't get up into the powerband? Rollers are a little. Cheaper sand a whole lot easier to swap than a contra spring. Remove 6 grams and see what happens.

Most of my money is spent on scooterparts. The rest is just wasted.

Whatever weight comes with the oko, maybe 9's. I'll drop some weight tomorrow and see what it does. I kind of ran out of time today and wanted to see what others thought. I was hoping for wheelie power, nope.

OKO OK
Greetings:
9s came with the Keli as well, according to trusty $15 HF gram scale. I backed down to 6s&7s (39g) for best performance, at about 8500RPM on the Polini 65.
If your vario "traps" your engine at 6-7K, it can't "climb over" unless a big hill or a gale-force tailwind intervenes. A 16 kitted like yours should easily exceed 60 once the shackles are off.

lighter weights and stiffer center spring will help
46mph is better than how I started
After assembling everything I decided to use mostly stock trans setup, stock pulley clutch even rollers etc and just tune the carb! that did NOT work lol took 15 jetting combinations and never getting above 35mph to realize I had to tune trans at same time

projects galore 
Yep, i looked through my pm's from you toast and found that one saying you were trying to tune carb but had problems since trans was stock. I'll have to run my 1k center spring till VT sends my 2k. Dropped rollers to 3 and 4's for first run, i'll post later what happens.

No go. Still topping out at 46 mph range. I tried tons of different roller weights (all the way down to 33 grams) and switched back from the SEF ramp plate to stock ramp plate with same results. I'm going to do some trans tuning before i scrap scooter out
. I guess i will take it to performance motorcycle shop and have them tune carb after i beef up the trans. I tried to tune carb from bottom to top using what i think is the recommended procedure. I seem to have the best take off and power at about 1/8th throttle, any less or any more and it acts like it's struggling. And temps won't go over 300 degrees, just gets near 300 degrees. Just a comparison...the wifes stock 2000 keeps up with me on take off and i slowly pull away then i get ahead more since i hit 46 mph and she tops around 40 mph.

so, what does the plug look like? i try to only change one thing at a time, that way you know if it has the desired effect or not. going willy nilly on everything all at once could work, or you could end up with a head scratcher, wondering which thing you did made the thing run weird. i would get the trans close then work on the jetting, which sounds rich, btw, then go back and fine tune the trans. at that point you may have to go back and fine tune the jetting. its a vicious cycle! but first check the plug. that will tell for certain if the A/F is close or way off.

Don't ask me that
. I forgot to gap it! But anyways, i'm kinda wondering if it's my cylinder head temp gauge thermocoupler not creating a good enough seal? The plug takes a 14mm thermocoupler. The thermocoupler i'm using is 18mm so the plug sits on top but might not be sealing that good, i will try a fresh plug without thermocoupler.
