Buy a 250...

What kind of performance improvements/gains are you hoping to get? I have the 190 kit, Malossi Mutivar, and a Sito+ exhaust. Never did a full tally, but that's well over $1K worth of mods once labor is included. I paid for it all with part of an insurance settlement windfall. If it had been out of pocket, I'd probably regret some of the changes.

Overall, I'm very happy with the 190 kit. It didn't change the essence of the scoot, but it made it spunkier. It was kind of like the scoot had been working out a lot. I have to say that it kind of felt like the scoot was eager for me to vegetable peeler the throttle. I was pretty impatient through the break in period-I really wanted to test the scoot's limits.

Off the line and mid were definitely improved, as was torque uphill. On the top end, maybe a 3-5mph improvement. But, yeah, you can definitely just chill, same as before. As far as MPGs, I tried keeping track for about a week but then slacked off. I've never kept close track of my mileage, though, chalking it up as "pretty damn good." If I were to guess, I'd say it's dropped around 5mpg.

My variator went kaput soon after, so I went ahead and put in a Malossi Multivar using mixed 9.5g and 14g weights. This has really smoothed out the acceleration curve. Off the line it's not as fast as when I put the kit in, but mid and high end torque are good. You can really feel it over 30mph. And it really moves when I hit the throttle between 40-50mph. Top speed isn't hugely improved, but I get there a lot faster.

This was when all the parts, esp. rollers, were fresh. I was going to go with lighter rollers on the next change to try to improve my off the line acceleration, but have decided to stick with the current 9.5g/14g combo to keep my high end for the long distance San Jose ride.

I did later try tracking my MPGs and they're pretty poor-under 60MPG. I've also put on some weight in the past couple of years and that has a significant effect on performance as well.

Not everyone will get exactly the same results, though. Some engines are faster than others. Others will react differently to the mods for whatever reasons. A lot depends on the rider and all the other myriad factors effecting acceleration and speed.

I've since switched to a Polini Max Speed variator. I prefer it to the Malossi; smoother delivery across the whole range. Better high end overall. Haven't really taken it as fast as possible, but had it up around 80 indicated today on a flat surface.

the set up and break-in of the kit as well as the other components are big factors... i thought that mix of rollers would be right for ya... let me know when you're ready to switch 'em out and we can screw around with the clutch to see if i can get you wheelies... rolling throttle wheelies...

best,

Dyslexia (dsylexai) is such a horrible condition. I read this is " Max Speed Vibrator."

That has nothing to do with dyslexia and everything to do with Freud.
