DR Pulley sliders - what weight should I use?

I have a 2011 Burgman 400. I want to get a set of these, as I worry about the bike on the highway constantly screaming at high rpm. Does the riders weight make a difference in the selection of the slider weight? I am a bit weight challenged, and was wondering if it made a difference.

There are those that will suggest that one gram either way will change your life. If you feel you need more performance, 18gm is a well respected number. If you feel you want to reduce rpm at cruise, 20gm won't hurt you. More important probably is keeping your variator tidy and smooth. Crud that collects will probably impact the transmission's behavior more than a 10% change slider mass. Sheave wear in the variator and torque multiplier will have a large effect on transmission behavior. I had 20gm sliders in for about 40K with sheaves of varying (and slightly deteriorating) condition and found the sliders worked well. When I rebuilt my transmission (once for practice and a second time to do it correctly), I tried 18gm. With a well lubed transmission and really flat sheaves, the scooter does feel remarkably different. Not necessarily faster, more like squishier. I saw much more variation in rpm when accelerating and it probably made the scooter a little faster. But the way I ride doesn't make it particularly noticeable. I now have a lot of miles on those sheaves and the transmission now feels much more locked up (during acceleration rpm tracks fairly consistently with speed). I'm at the point now where I don't know if I want to jump into another set of plates. I figure if I do then I'm committed to riding the burg to 130-150K. I find I'm stealing glances at ads for Victory cycles which historically has meant I'm about to switch mounts. I'm sure that if I did replace sheaves, everything would go back to its normal squishy mode and I really would like to find out when I'd have to park the scooter and walk home. That's my definition of EOL.

This seems to be a mini can of worms (vs the maxi can of worms for oil discussion) but 18 to 19 grams seems to be a very common weight.

I am likely to add sliders this spring.

Also may add a hit clutch to improve the lower end where I find myself while commuting.

I installed 19g sliders in 2012 and am happy with them.
Might try 20g someday, if a few spare Jacksons fall into my hands though.

The Schofield Kid: Yeah, well, I guess they had it coming.
Will Munny: We all got it coming, kid.

Don't know if you're taking votes on this but I am curi-anxious to know the longevity potential of this machine as well. Go for the new plates.

Growing older together with a great ride is one of those rare pleasures this journey has to offer.

And may your never have to leave your steed on the roadside of the highway to Heaven and hoof-it back to the ranch.


Let me ride 'til I croak.

Adding Sliders is the SMARTEST thing that you can do, next to using Synthetic lubricants in your engine and final drive.
Your RPM's will NOT go HIGH when using the sliders, your rpm's will DROP considerably compared to the stock rollers:
While 18 grams is a popular choice, as they provide a little better performance and acceleration than the stock rollers, I chose 16 gram sliders for even better performance and pickup, especially when riding 2 up. If you ride 2 up, or are "weight challenged" as I am (315 pounds), I definitely recommend the 16 grams. When I ride 2 up, the poor 400 is having to tote 540 pounds of weight plus another 30 pounds of GEAR, the Rear Suspension is set as tight as it can go on setting #7, so the 16 grams sliders are essential to me. The RPMS do NOT go high. The only way the RPM's can go high is if they are improperly installed. They must be carefully installed, holding the variator tightly together, until it is fully seated on the crankshaft. The sliders are held in position by being "clamped" in placed between the variator body and the ramp plate. If you allow any looseness in the variator while installing, you might let some of the sliders slip out of place, so be careful installing them.
Here is the SPEED VS RPMS chart for my 16 gram sliders:
16 gram DP Sliders:
2008 Suzuki Burgman AN400
Cruising at indicated:
Speed RPM
30 = 4300
40 = 4800
50 = 5200
60 = 5400
70 = 6100
80 = 6800
90 = 7800
100 = 8500
Wide Open Throttle acceleration from 40 mph to 60 mph = about 6800 rpm
Gas mileage runs City about 48, Highway about 65 with steady throttle.
The 18 grams sliders should reveal slightly lower RPM's.

Cheers!

I think depends some on how you ride, do you need more torque at lower RPM or what to cruise at lower RPM (and have less torque at lower RPM). Can't have both.

I went 1 GM higher with the sliders a (using 19GM). Very satisfied with the results. I posted speed vs RPM sometime ago (when I made the change to sliders).

My rides are in East TN - curves, hills and steep hills and mtns, steep switchbacks, and some gravel roads (not rough trails).
So, I need some reasonable amount of torgue (especially for steep switchbacks). 19GM works

I am not about drag racing or seeing max performance at lower speeds, do ride double with the wife (only on occasion and not on the adventure roads mentioned above). I weigh around 210lbs dressed to ride and she is around 135lbs dressed to ride.
So, I do not need maximum torgue. 19GM works.

19GM works great for me -- plenty of torgue for my ride conditions and drops RPM a lot at speeds (see the RPM VS Speeds I provided in another post). By Te Way, I seldom run over 70 or 75MPH, sometimes 80 mph when passing.

MAX Speed was reduced some ( I think areound 90 or 95 mph) as the engine will not pull to red line with the higher gearing.

I would appreciate if you could post your RPM VS Speeds chart in this discussion thread, instead of simply referencing it, making us have to go search for it. Or you could put a link to the RPM VS Speeds, in your post. Thanks.

What is/are the sheave you speak of?? Is the face of the variator? Different terminology that I've heard b4.

130-150K, as in thousand? Boy I LOVE my Burgmans .... I have a 400 and a 650. But 130-150K for the 400 seems overly optimistic if not unreasonable. To me. IMO. YMMV
