At 18,560 Miles on my 09 400, I plan to remove the covers and check my Belt for wear. clean, Etc. before Spring arrives. I plan to order a new belt just in case it is needed but I wonder if the Rollers could need to be replaced also. How do I determine if they are worn? I cant find any dimensional reference to them as a checking point. The OEM Rollers are 19 G But I read several posts that indicate lowering to 18G is advisable to reduce RPM. Any advice and comments is appreciated.

18 G rollers will increase your RPM's and deliver better take off speed and lower top end however if you use 18g DPS's initial rpms during take off will increase but at highway speed your rpm's will decrease by a few hundred giving you better fuel economy.

I would say based on my recent experience my left over 2011------20,000 miles, belt replaced (wear item), front pulley, rollers scrap!! still warranty, Suzuki paid----real professional shop Dalton GA. I would replace all with OEM parts, period-----easier if repairs needed in middle of no-where. Now based on near 300,000 miles of rubber band drive scooters-----the drive line is the weakest(and expensive link). Carry take off belt as spare----if stuck, dealers will never have one in stock to keep you going.

I think the stock rollers don't wear, at least I've not read any threads about them wearing. Mostly, they will rattle when there is belt dust in the variator.

As for other rollers, I think you mean sliders (such as Dr Pulley) which are not round, I have 19g in mine, and I would buy 20 or 21 g if I did it again.

Heavier sliders = closes the variator sooner, so it "shifts" into "high gear" sooner.
Lighter sliders = more revs at take-off. So smoother launches.

Also, the sliders close the variator more, so the belt rides higher = "higher gear" = theoretically better MPG. Compared to stock rollers.

If you've never cleaned out the belt dust, you will be surprised at how much there is in the variator. At least I was 8)

The org rollers should weigh 19g and be smooth with no flat spots, mine were like new at about 8000 miles
when I swapped them for 18g sliders.

My dealer replaced my variator rollers at 28,000 plus miles...
yep...there were flat spots...they sure weren't rolling any more. :?

Rollers usually don't roll they slide, that is why they get flat spots. That is also why Dr pulley sliders are used by so many people. If your rollers are in need of replacement you will know just by looking at them.(flat spots) Dr pulley sliders seem to last longer because they start out flat and stay that way.

I changed my belt at 20,000 miles and some of the rollers had flat spots. The rollers are in pairs so I swappaed them round so the flat ones are with one without flat spots. That will make tham last another 10,000 miles at least. Changing the belt made one hell of a differance.
