It's good to find this forum!

My Vino is great fun now that I've derestricted the exhaust and variator. What a difference!

The top end speed leaves a little to be desired where I ride though. It'll go 40 -45 mph depending on wind, slope, etc. but listening to the engine rev it sounds like the transmission hits it's top range about 35, and all speed above that is reached by RPM increase alone. I don't enjoy the sound of that little piston screaming, and don't want to be causing excess wear and tear, so I'm thinking of installing an aftermarket variator to get a higher gearing.

Any suggestions as to: will this help, what brand to use/avoid, other solutions?

Thanks for your help!

According to your post, you are right on the engine rev to get more speed. A variator will help you on the acceleration, not really top speed.

If you want a higher speed at lower rev, you need gears. But then you will need more power to push the gear. If you change the gear, it is like you start off your bike at the 3rd gear, not 1st. So you will need more power, like a 70cc.

A pipe will change the power band of your cylinder and allow your cylinder to rev higher.

Thanks for the help.

What I really want to do is have a wider range on the transmission...keeping the low end as it is, but adding a higher final gear ratio for a higher top speed without revving so high. (It feels like the engine has enough power for a little higher top gear) If it were a car, I would change from a four speed to a five speed.

If I understand it correctly, changing the gears in a scooter is like changing the rear end in a car: It raises the low speed gear ratio as well as the high. Not good for the fun factor.

So am I making sense? I'm just learning how these things work (I had no idea how the variator worked untill I opened it up to derestrict!)

I'm still not sure if a "wide range" variator is the cure. All advice is appreciated!

like I said try some of the other things, rollers, spring first... as the over range is around $350! so it'll be an expensive upgrade...

I'd also change the gears if you do the over range... as it'll give some top end and keep the bottom end as well with the combo of the 2 parts!

Well, this is just my personal point of view, I will say if you leave the cylinder as stock 50cc, you are pretty much bound by what you have. An overrange w/gears will be what you want as per your post, has more torqu at low rev to push gears. The problem is I don't know how well the stock cylinder push the overrange. You may have to consider it serious.

The way I see it is it is just a 50cc, it has its own limit. Overange/gears requires power, which means 70cc or even more...If a 70cc, then you have to consider other factors, noise, reliability, gas milage, brake...

I would suggest either be have with what you have or keep spending the time and money until you are satisfied.
