Hi, am thinking about installing some Dr pulley sliders as I want to improve acceleration from standstill but also smooth out the low rpm vibes. Was wondering which weight would achieve both of these without affecting the mid-range too much?
Many thanks.

I tried the J Costa variator on my 2007 Silverwing and really liked the smoothness and acceleration. I have tried both the 26g sliders and the 22g sliders on my 2009 Silverwing. Both weights seem to smooth out the low rpm vibes, but the acceleration with the 22g sliders is much quicker - nearly as good as the J Costa. The nice thing is that even with the 22 g sliders I average more than 50 mpg. The 26 g sliders were even better - maybe around 55 mpg.

I had the 22 gr and have the 28gr sliders and it runs smoother IMO. It really depends on the acceleration that you are wanting. If you really want a lot of it than get the lighter ones.

OK, thanks for the replies, 24g sliders might be worth a shot then.... but if I install these will I sacrifice any mid-range and/or top end? Thanks again gents.

You can mix them as well! I run (4) 22g and (4) 28g with great results.

I think the sliders will actually improve your midrange acceleration. I may have lost a couple of mph off the very top end, but I can still hit an indicated speed of 111. Keep in mind that I live at an elevation of 5,800 feet, so my stock hp output is probably about 18% less than a guy who lives at sea level.

squasher,

I wouldn't be concerned about losing top end since it would only be a few miles an hour. And how often do we cruise at 100 mph or so, so that would be my least concerns, for me that is. The acceleration will be better all over though.

Sorry I didn't finish answering your other question. The DP sliders smooth out the midrange very nicely. The only thing you will sacrifice at the top end is mpg, but we already know these beasts are thirsty at those speeds.
