Dr. Pulley sliders - which ones do I have?

Hello,

Recently acquired 2003 Silverwing with 19,900 miles.  A glance through the maintenance records shows Dr. Pulley sliders were installed in late 2015 with belt change around 16k miles.  However, the weight of the sliders is not recorded in records, so I don't know what's in there.  I have lost contact information for the seller and cannot contact him.

Without disassembling the variator, is there any easy way to figure out the weight of the sliders contained therein?  Can we "approximate" based on full throttle RPM's?

The scooter seems to have pretty strong acceleration.  However, when giving full throttle after allowing the clutches to engage, the engine climbs to 5100-5200 rpm and stays planted there throughout the speed range until above 55-60 mph, at which time the RPM's finally climb further with higher speed.

I would think more aggressive Dr. Pulley sliders (say 24 gr) would allow the engine to climb further into the high-RPM power band than 5100-5200 RPM.  Perhaps I have less-aggressive sliders in there (26 or 28 gr), keeping full-throttle RPM's a bit lower.

No top-speed test runs and "cruise RPM" runs have yet been performed.

Any input based on WOT RPM observations is appreciated.  Thank you!

Since most of the members here are 'mature', regretably our psychic powers aren't what the once were. So you're just going to have to disassemble the variator and weigh the sliders or rollers. There are no markings on the sliders or rollers.

I put 24gr sliders into my Silverwing.

It'll peg right at that exact RPM range (5100-5200).

Don't know if yours are 24gr, but I hear those are a popular choice.

Hope that helps!

I plan to replace the standard factory rollers (28x20 28gm) on my Honda 2013 SW T600 for eight DR-Pulley 28x20 26gm. Here in Flanders Belgium, terrain is quite flat, so I don’t really need the extra oomph to get up mountains, also my typical highway cruising speed is about 110-120km/hr, engine should rev a few hundred rpm lower than standard factory setup. By changing to sliders, I also hope to solve the drive belt slapping the bottom of the aluminium drive housing around 3000rpm(std rollers), but that is wishful thinking. I expected the smoother acceleration the sliders provide will illuminate or minimize this annoying problem (well known to everyone including Honda).

I will also change the drive belt at the same time, original belt done 22500km. My local garage told me if you change the drive belt before the recommended 24000 km, light will come on the dash which you can’t reset until the 24000 service km is reached. I find this hard to believe, if everything is working properly i.e. on slippage of the belt, etc..! Is this fact or fiction??
My apology for combining topics…!

The v Matic light can be reset any time, hold the two dash buttons in, then turn on ignition and keep buttons in for 5 sec until the indicator light blinks, release button and light should go out and not come on again for 24k km.

As Terry says, yes, you can reset the “V” light at any odometer mileage. But do be aware that any time the light is reset the “V” light clock resets to a new 24k km/16k mile interval.

When using lighter rollers/sliders is not uncommon for the “V” light to randomly come ON, usually during an aggressive ride. It is just a case that the ECM & Combination Meter “sees” that the rear wheel is turning faster than the RPMs are supposed to be for that speed. So it interprets that anomaly as that the belt is worn & slipping and turns on the light.

Point here is that if the light comes on at some random interval and the bike is otherwise acting normally, don’t worry. Just reset the light. But do make a mental note that you still should replace the drive belt 24k km after you initially replaced it. The “V” light / belt mileage will be out of sync until you reset it again at the next belt change interval.

Thanks guys, great feedback on the light. I am really curious, changing to DR-pulley sliders will help/solve the problem of slapping belt around mid-range...!

I’d be changing the belt first. Can’t see that the rollers are going to change belt slap.

Thanks Terry, once I’ve fabricator a home made variation holder tool (example on the forum) I’ll have a go at changing the belt. don’t see any real problems. There are some good videos on YouTube to help the first timers like me.

Hey Peeps,

Yes, I've had my "V" light come on a couple of times. Here's a question: If I change my belt just cuz say I want to - no "V" light on - can I reset the "V" light as per the procedure above, even though the "V" light is not on? Hmmmm...

Jon

Try it and see I suppose.

I reset mine at 13k and it still came on at 16k unless I did it wrong. I think it just comes on at 16k intervals 16-32-48 etc. but what do I know.

I did my reset at 8,500 miles there's 18, 3xxx on it now and the light hasn't come on since 8,500.

I guess that ? is answered then. My next belt change due at 29.5k don't know if I'll hit that mark this year but going to try 27k and this weekend will add some for sure. New rear tire installed today weather is perfect down this way next 4 days. Sept. is the best time of the year not to hot not to cold .
