Nireen,
Where the heck did you order them from?
That's crazy!
For years I mailed small packages to Europe, with the simple to fill out customs forms, for $10 to $15.
No way is there $65 worth of stamps on your little package.
Shame on that seller.

So stig is there only 6 the bike needs. My manual shows 8!

YOUR MANUAL IS CORRECT 8 IS THE MAJIC NUMBER, SHOULD HAVE CALLED dR. PULLEY WOULD HAVE BEEN RIGHT FOR YOUR RIDING STYLE

Oh crap! :( What a frustrating thing. First I pay an arm and leg to have it shipped to me and had to wait 3 weeks and now this. :(

I'm afraid to use them
4 weigh 14G and 4 weigh 15G
I made the measurement on my wife's precision scale
I think if I decide to use them, I will install interleaved

All must be the same!

A pretty important part of any scooter's performance and reliability. I would hesitate to put $9 knock-off parts in my 300cc scooter.

They are not, I already told

You're right. It's the same thing as buying an Iphone and using plastic cover for protection
But here in Brazil we come up with a problem. The purchasing power.
The minimum wage here is about 970 BLR
A set of Dr Pulley rollers costs 350 BLR

you can make them all the same Wt. get a larger drill then the hole and just touch it to the brass metal and weigh it to see how much came off, 1 gram is very small
-
De dee, genius! But practical as well. It occured to me this is how they got that 14.5 gram weight! 4 at 14 grams and 4 at 15 grams, each weight placed opposite and staggered. Fulfills the spec weight but I doubt it was dynamically the same!

Not nessasarily.... I also have different weight rollers on my 350DT..4 weigh 14 gr and 4 weigh 16g.You get the best of both worlds. Lower and higher RPM speeds.
BTW.. I gave a DT200 modified to a DT 350
Hope this helps!

I said that when I was young and silly. I am now much older and wiser! Har, har!

Here in Italy is this a very common practice to put interleaved weights into your CVT. Works out pretty well and saves a lot of drilling out or putting 2-component putty reinforced with brass-shavings into (respectively) too heavy or too light weights. I personally prefer straight weights, but if I feel that there would be a little bit of revvs or end speed in it, then I don't hesitate drilling off or plombing in a half a gram. Or mix weights until I'm happy with my scoots performance.

Very interesting. How do you have them arranged, are they staggered out?
Also would like to hear about your DT200 modified to as 350 someday!

Small scoots use 6 rollers, large ones have 8 rollers.

It's a bad idea. The pressure against the belt will be inconsistent and cause premature wear to the aluminum parts and the brass bushing.

But a lot of people mix the weights, and enjoy the results.

No problem doing that. That's how you get 14.5gm weights.
