Vibrations, revisited!

I'm new in the big family of Silverwwings.
I bought mine used 2 weeks ago with 15000km (±10000mi.) and love it.
However, I have 2 issues: vibrations from standstill to ± 20mph and numbness in my hands on long trips.
I have read many topics on these 2 subjects in this forum.
For the initial vibrations in the dash upon accelerating from a standstill, I have read of two possible remedies: windshield isolation and changing the pulley rollers for Dr Pulley sliders. I find it hard to believe that what happens near the rear wheel affects the Tupperware in the dash But if it is the solution, please let me know!!
For the 2nd issue, adding handlebar weights should resolve the problem.
Am I right on these 2 counts?

The engine is a stressed member of the frame. Any vibration from the engine/drivetrain gets transferred to the body.
Grip Puppies foam grips resolved any tingling in the hands for me.

Sometimes when getting a new ride it is best to give yourself time to adjust before making too many changes. It is good to research solutions others have found useful, but you need to see what fits your riding habits. What works for one might be of no use to another. Besides, you can classify all your riding as doing research. Any excuse to ride is good.

Thanks to bigbird and Hi Yo for your insight.
I took the windshield off and the vibrations persist, so bigbird's explanation sounds realistic.
Will the Dr Pulley sliders help to diminish or eradicate these low speed vibrations?

Yes. Most of the vibration is caused by the engine being asked to accelerate at too low an rpm, well below its torque producing zone. The vibrations you feel are essentially the engine lugging. Dr. Pulley sliders bring up the accelerating rpm out of the lugging range, so not only do you get much less vibration, you also get much better throttle response and acceleration.

Thanks, big bird: do you know of any Canadian outfits who sell this product, or must I go to the US?

Ayjayroy try giving more throttle on takeoff then adjust the throttle to the speed you want to go. A big mistake people new to the CTV scooters is too little throttle trying to start slowly to get used to the scooter. The problem with that is the clutch doesn't fully engage at low RPMs. Try the higher throttle thing and see if it helps, my guess is it will. Oh and welcome to the forum.

Ayjayroy, You could also try the solution that worked for me suggested by JeffR. Hold the left brake handle tight and rev the engine up to 4000 rpms for about 4 or 5 seconds. I had vibration for about the first two or three stop and goes but this cured it. Now it takes off very smoothly. I did this a bout 3 days ago and haven't had a problem since. It's worth a try.

I was bothered by the vibrations as well when I got mine. It was relatively not even broken in, with 3400 km. But I found out that it is a common problem, and I am more at ease. As for the grip problem: 2 things you can do; loosen your grip just a tiny bit. I also found that about 3 wraps of a piece of black non-slip matting secured with zip ties works well for me.

I will try that solution tomorrow if weather permits.
Regarding Dr Pulley sliders, I see that the 28x20 ( has different weights.
One sight reccommends the 22 on., and then I watched a video on YouTube that shows how to install them and they are installing 26 on. sliders. What is the incidence of the weight on the performance of the SW?
Hum.... any suggestions as to the correct weight to use?

Quite a few of the members here are using 26gm Dr Pulley sliders, while some are using 24 gm sliders. All of them report favorable results and increased performance. Personally, I use 28 gm sliders and find them a big improvement over the OEM 28 gm rollers.

If you are interested, I have a new set of 24 gm Dr Pulley rollers, not sliders, I'm willing to sell at a decent price. Meanwhile you can check with BuggyPartsNW (https://www.buggypartsnw.com/) the N. American distributor for Dr Pulley to see what they have available.

What Dale suggests will deglaze the clutch pads. But it will only be temporary unless you use a reasonably heavy throttle on takeoff. I used that method to deglaze my scooter when I first got the chattering of glazed clutch pads. After that I always made sure to give enough throttle to engage the clutch pads quickly. I have never had my clutch pads glaze over again. I first had to deglaze my pads in less than eight to ten thousand miles. Now that I make sure to engage the clutch pads quickly I have over 51,000 of chatter free miles.
