I will shortly be changing the drive belt and roller weights on my A7 s/wing.Having just received a workshop manual this seems an easy enough job to do.I have read several topics about Dr pulley sliders but my question is can i fit dr pulley sliders/weights to a standard Honda variator.I want to get as good a MPG as possible but i tow a camping trailer so i am not too bothered about faster acceleration just a general good all round performance. Thanks.

Thanks for the reply,my next question is does anybody know where i can buy them in England and what weight would i need to get the best MPG

VMax: I may be wrong here, and if so, I hope others will jump in and correct me, but if you're pulling a camping trailer with the Silverwing, I don't think you want to use lower weights than the originals. Lower weights give higher rpm on takeoff, and lower RPM's at cruise. Its the top end lower rpm that I would think might put too much strain on the scooter. Frankly, I'd stay with the factory weight, be it a Dr. Pully or OEM.

As to your belt, how much milage do you have on it now? Might want to examine it carefully, measure it, and if its still in spec, continue using it.
I ride with several other SW owners, one of which has over 200,000 miles and is only on his second USED belt. His dealer provided the used ones that other customers insisted be changed at the specified milage in the manual, despite dealer advising against it.

vmax: there is no agents in the uk that sell dr pulley sliders ref: unionmaterials.com
to order some on union materials website click on agents then onto germany www.drpulley.info mr.diestel on the website click translate to change from german to english register your details and buy your sliders 28x20mm x24g sliders 45eur +3.50eur postage can pay with paypal the exchange rate 1.12eur to the pound today you may be better ordering the dr pulley sliding pieces at the same time sp2820-w they are 16eur

This guy in Oregon, USA will ship worldwide. Not sure what his international shipping would be, though. He's about the same price for the actual sliders as Buggy Parts NW.

hi all
can anybody tell me before i make my final decision to order dr pulley sliders have they noticed any increase in belt wear or belt slapping wear on the outer case with the belt running higher up the variator pulleys with dr pulley sliders in, is the dr pulley sliders wear rate lasting as long as the stock rollers

Definitely no belt slap and no signs of contact between the belt and aluminum housing. I have had less belt dust in the housing with the sliders than with either the stock rollers or J. Costa variator.

thanks bigbird
have ordered my 24g dr pulley sliders and sliding pieces have opened up the variator today just to see how it all goes together had no problems and was suprised how much dirt there was in the variator housing and rollers my bike has only 3200 miles and is 18 months old there is belt rubbing marks on the aluminum housing have give it all a good clean and put it back together for now hopefully sliders will be here next week to fit them

Sorry I asked questions. . . seems they have been answered except for one thing. I notice on the "sliders" out of Eugene, Oregon, they are 26g. Do they have other weights? Guess I'm pretty ignorant on this subject but do want better gas mileage.

Dave:
I had the 26 g sliders and liked them quite well. I was able to get 59 mpg if I was careful. I wanted a bit better accelleration so I switched to 22 g sliders. I still get about 55 mpg and the accelleration is about as good as I had with the J Costa variator.

I ordered two sets of sliders (28&26g) from Buggy Parts. They did a great job in sending them out quickly and e-mailing me a tracking number etc. But after three weeks they hadn't arrived. Tracking via USPS told me they were in the UK so entered the tracking number into the UK postoffice website, but didn't get a hit. Turns out they were with Parcel Force and were in the Rotherham depot waiting for me to pay £28 duty! Why Parcel Force didn't tell me, I don't know. I like them, so I'll probably order a set of 24g and 22g in the future and sell the spare 28g set that I didn't install.
