Vivo, where is that superb road?? It took about 4000 miles for the Yager to "break-in" and the mileage to start climbing.....

except uphill, you'd have that thing wide open the whole time to get up it lol, i plan on doing a steep one soon, i know i'll be bogging compared to when i took it on my KTM Supermoto

That's what Dr Pulley sliders are for!
Drop in some 10-15% lighter ones then your stock rollers, and it'll go uphill
as well it goes on a straight now, and will probably lower your revs near the
top end.

Ah, Baguio! Always wanted to go there when I was in the PI. Never made it. Definitely a great lookin' road!

What are the standard weight of rollers for the 200i? I will HAVE to inspect the CVT soon and might just put in a set of lighter rollers or sliders while I am at it.

Hey Crossbolt, I believe the standard weight is 17gr (20x15). I just swapped mine out to 16gram I believe. Rough couple of weeks, my mind is mushy but I believe the stock number above is accurate.

Gee - I'm envious.  For about the first 4000 miles, I was regularly getting 87mpg.  Now I can't seem to do better than 75mpg.  I originally thought this was due to a dirty air filter and old spark plug, but I'm still mpg challenged at 5800 miles.  My Yager is 15 months old.

i thought I read in another thread that when you swap out the weights the acceleration is better, but lose on the top end, which would seem to be correct

swap to lighter weights = better acceleration

Lighter weights = Better acceleration, Heavier weights = Better top end. I have 16g sliders in my Yager and I just ordered a set of 19g sliders. I do a lot of riding at 60 - 65 MPH. I'm hoping the RPM's will be lower at top speed. I don't know how much you people weigh but my Scoot, lugging my 200lb butt around only gets 65 MPG. Granted I'm usually riding WOT.

Lighter weights = Better acceleration, Heavier weights = Better top end.

This can be a bit misguiding as people will tend to assume that heavier weights
will give the bike better acceleration near the top speed OR a higher top speed.
The first won't happen, and the second will happen only very rarely.

I have 16g sliders in my Yager and I just ordered a set of 19g sliders. I do a lot of riding at 60 - 65 MPH. I'm hoping the RPM's will be lower at top speed.

What's the stock size of the weights?
If it's anywhere near 16g, you probably overdone it with 19g.
Because of the way sliders work, even going 10% less then stock rollers can drop your
top speed, because it won't let the bike rev out high enough. That's what happened
to me when I went from 15.5g stock round ones to the 14g sliders on DT300.

It's probably even more pronounced with smaller engined scoots.
I'd move 0.5g or 1g at a time.

Try using fuel with NO ethanol  and call me in the morning!

I guess the only way to find what is in my variator is to disassemble and weigh....

Well I installed the 19g sliders last night. I'll be damned if I can notice much of a difference. Top end is still 65 MPH @ 8000 RPM. Guess I need a bigger Scoot. I'm sure the Wifey won't mind.  ::)

Last two fill-ups.  84 mpg for both :-)

I did it and I'm glad.

I can't believe the mpg's on the Yager! I have 3700 miles on my scooter and get an average of 93 mpg. Love the Yager!
