Roller Weight Size?

[jsorvik]

Does anybody know what the size/weight of the stock roller weights is in a Sunset. I have seen reference (as far as size) to both 16x13 and 15x12. . .

what you need to do is
 remove the varator and weigh & measure the weights..
i have a chart but the size is listed as 17x12  according to MRP-Speed
 just remember that the varitor nut is reverse threads
FYI: I stock some DR.Pulley sliding weights in case you need some

Are the sliding weights proven to be much better than rollers?

I understand the concept of them but is there any downside to the sliding weights?

Also Harry...or antbody else that knows...whats the big advantage of replacing stock with say something like a mallosi or pollini or similiar variator

yes sliders  do give some advantages .   i use them myself.
the only draw back  that i have found is that they
sometimes (rarely),  in low speed all of a sudden they can
cause the scooter to feel like you just released a clutch lever
 making the scooter lurch a bit  when you take off from a stop or slow roll.
but its nothing to be concerened with .
 
gennerally aftermarket variators have a different  configuration of the ramps
(where the rollers sit and travel)   allowing for a quicker,  more steep  travel of
the rollers to get to the high range(they get into faster/sooner) , also some variators
 are a slight bit bigger in dia.  than stock ones.

Harry,?
Doesn't Cobra have a parts list for their scooters to get roller and belt sizes?  Also are the variator threads reversed only on the TBG's because I took my Yamaha Vino variator off to get the washer out and it was not reversed. 

[harry]

most part lists are just listed as numbers with no specs
for example the belt:  GE506RB01 V-BELT, DRIVE 
however i think that is a Bando #
 
for rollers the manual says: 490045 ROLLER COMP., MOVABLE DRIVE FACE
i did weigh the rollers and they are 8g ea

yes the reverse nut is only on the TGB
