ok just want to know.

At least on my agility, belt size issue proved to be factory restriction.
After some tune in, got  as much as 20% top speed increase!!
I did some examination and there is a space for even bigger front variator.

A little notice: in my experience, end performance depends on belt manufacturer and their methods of measurement, belt quality,
height, width and angle(potentially good or bad acceleration, top speed...) , roller weights, clutch torque spring, generally the whole variator system set up.

[streido]

What set up are you running now then? What your top speed and acceleration like, and how is it uphills?

Just wondering cos im still toying with the idea of trying 5g rollers. Currently use 5.5g, 1000rpm torque, 1500rpm fly springs, race variator, 82 jet, derestricted, nakura belt. Get 45-48 on the flats hits 50 down good hills, 35-43 up small hills, 25-32 up steeper hills. All speeds on speedo in mph.

[woodcutter]

Your configuration is very simmilar to what I done on my kymco.

-82 jet
-CDI de restricted
-5.5 gramm malossi rollers (optimum for my scoot ). With stock variator I could use rollers from 3.5 up to 8 gr and top speed was the same 'cos belt was too short. Now roller weights makes a lot of difference. I tryed 5.0 gr, good for steep hills but loosing 3 - 4 mph top.  
-malossi multivar
-white torque spring. I also thoroughly cleaned driven pulley, clutch springs, paper sanded pads and bell and greased torque drive. What a difference. After 16 000 km it was so dirty and sticky.
- 748 x 18 x 8.5 cm  30''  belt

Much better off line acceleration, 35 -40 mph up hills(a little better with 5.0 g) and 45+ on flat road(garmin gps measured). But these performance are very sensitive to parts calibration and wear.

Guess quality big bore and up jeting is the next step but I'm not going to invest any more money because it's my second scoot and I'm very satisfyed now considering it is 50 cc.
I just do regular maintenance and it's running fine :-)

From reading past posts on improving performance of AG-50's it seems to me that the riders weight had a lot to do with the best setup for them.  For example 200 lb.+ riders seemed to favor 5.0g or lighter roller weights. 

[streido]

You calling me fat Encya?  Im only 12 stone so pretty light considering in 6ft 2". Anything over 5.5g and I just lose the revs and then lose the power. Even tried going 5.75g and that was too heavy so returned to the 5.5g's. Usually revs stay around 6800-7000 rpm and its good like that for me. When the revs drop below 6500rpm I lose power.

Even thought of trying 4.5g or 5g rollers. Want to get 100% happy then go for sliders.

[streido]

Just to let you know 12st is around 168 pounds I think.

[woodcutter]

Malossi final transmission gears are advertised as a 10% more speed upgrade.
Anyone had experience with these or any other manufacturer?

[streido]

Maybe worth putting up a new topic for that question woodcutter? Someone discussing final gearing on another post I read not too long ago, maybe sidthesloth was involved in the conversation I think.

Ok, you're just 10 lbs. more than me.  So I may try 5.5's at a later date.  I just want to get some life out of my 6.0g sliders first.

[streido]

Thats why I want to find the best weight that suits me before I buy sliders, got about 4-5 sets of different weight rollers in my garage I tried so far, 5.5g has been the best performing for my needs. Not tried any lighter than that yet but plan to buy some sliders soon.
Maybe try 5g rollers 1st tho to be sure, just in case I prefer them.

[woodcutter]

streido, you're right about gearing question here. I'll leave it for now as it is 

anyway, today I drove on a 0.5 mile light downhill road and got top speed off the tacho scale but gps said 53 mph.
this was with 3 x 6.0 g and 3 x 5.0 gramm roller weights.

just to mention, I'm weighting about 70 kg or 160 lbs
and for now I'll change to 6 x 5.0 g for better take off and hill terrain driving

[streido]

Let me onow how the 5g rollers work then will you? Were both the same weight and around here its mixed terrain, flats and some hills. I sometimes die down to 25 on steep hills and I wish I could just down shift but it stays in too low a gear. Thinking 5.5g rollers are slightly too heavy but with 5g rollers it would keep my revs up more and help on the hills,so be interested how they work out for you.

Lately my top speed seems to have lost a bit, used to easily get 48mph showing on flats now I only get about 45, maybe 46. Onow its only 2-3mph but its bugging me, maybe check my valve clearances at the weekend, see if that helps.

Remember let me kno how the 6x 5g's work out if you try it.

[woodcutter]

well, today I was busy and worked on a roller weights set up.
A lot of work on cvt cover and variator removing/installing and test drives  

I'm 160 lbs, so:

6 x 6.0 g - too heavy, average acceleration and takes too much time to top speed. Uphill is very bad and droping rpm's low but I guess mpg should be a little bit better. Mainly for flat roads.

6 x 5.7 g - better than 6.0 g but still not good enough.

6 x 5.5 g - optimum for acceleration/uphill/top speed. Top is 4 mph less than 6.0 g but gets me there faster.

6 x 5.0 g - best take off but mid-range accel. is average (too high rpm's between 15 and 30 mph), after 30 mph accel. is smooth and constant all the way to the 45 mph. Although, steep hills are not problem and rpm s are high and pulling up with no problem. less mpg  'cos engine is revving high. Mainly for hill roads or when riding passanger back and not for flat terrain.

3 x 5.0 and 3 x 5.5 g - as much as 6 x 5.0 g but mid-range a little better.

3 x 5.0 and 3 x 5.7 g - even better than previous set up, better start, even better mid-range and ok top.

3 x 5.0 and 3 x 6.0 g - in my oppinion the best one. got all performance of 6 x 5.5 g but also better off the line and better top. Hills are not the problem and it's pulling up even better when I release throttle for a second or two and get it opened again. flat/hill terrain optimum. The only thing I'm concerned about this 3 x # and 3 x # set up is variator balance and uneven rollers wear 'cos I wasn't using it enough to make sure about this one. Anyone had some issues, please let me know


That's about result of my testing.
Hope I didn't choke you with this one                

[sidthesloth]

Good work. If you space them correctly, balance won't be a problem. The heavier rollers will wear prematurely but, if that is a setup you like, it might be an acceptable compromise.

wow woodcutter  your the roller master. which ones are you staying with. right now I have 3 5.5 and 3 6 need to go back to 6 5.5 when my pocket book lets me. Im a little slow going up hills now with all 6 being 5.5 I do a lot better.
