Just to give feedback on installation of the above:

I installed the 28g units as I am happy with stock performance and was more concerned with fuel economy than more acceleration. Ron (Trouble1100) helped me change the belt, sliders, slides and bolt and washer. Yes I used the OEM belt.

The scooter ran great before the upgrade and runs great now. Not much change. My OEM rollers were OK and probably could have made it through another OEM belt w/o replacement. However I had the DR sliders so installed them.

As to performance, the scooter is about the same off the line but a bit better at passing at 55 mph plus. I have put nearly 600 miles on the sliders and the fuel mileage is about 2 mpg better. Most people state a drop in rpm of 500 or so at cruising speed. I am seeing about 200 rpm less.

In summary, the DR Pulley sliders are supposed to last longer than OEM. My OEM rollers could have done 30K or so. The sliders cost nearly 60 dollars USD and the stock Honda OEM rollers are 20 bucks at Partzilla. So in reality the DR units would have to last 90K or so to pay for themselves. Can they do it? Not sure. But the fuel savings will help in the long run.

So hype aside, if $$$ is a consideration stock rollers work fine. If you have the extra dosh the DR Pulley units work well also but cost more. I have put over 600 miles on the change so I have analyzed this to some degree.

Would I use DR Pulley sliders again? If they last longer yes if not, no I will switch back to the stock rollers. My 2 cents and YMMV.

The heavier the sliders, the greater the cruising rpm drop.
The biggest drop is from just going from stock rollers to sliders, about 500 rpm drop at 100 kph.

I have used the 26r and 24 gr. The 24's gave me almost 500rpm, the 26's a bit less.
I believe the oposite.The havier has lower rpms

I found that the lighter the sliders were for me, the farther the belt climbed out towards the edge of the sheaves.

I had also wondered what the difference in RPMs would be so I sent a e-mail to Buggyparts NW this morning and got this reply:

------------------------------------------------------------------------------------------------
The 28g would have lower RPMs at higher speeds, compared to the 24g.

For what it's worth, I recently went from 28g down to 24g and didn't notice a significant change in RPMs at 70 indicated, still about 400-500 reduction from stock rollers.

That sounds definitive. I'll edit my post.
