DR Pully and Rider weight...

This may have been covered but I did not find it... Sorry if I’m beating a dead horse…

It looks like the general consensus is to run  26 or 24 gram Dr Pulley 28x20  Sliding Roller Weights.  I have  found lots of posts on how they perform, but the one thing I cannot find is general load of the silverwing. I’m fat, and I ride with my wife( who is not fat). Total load is 400-450lbs if we were loaded up with us and stuff. The stock s wing is working just fine, but I would like “more” like everyone else.  What I want to know is going to a lighter weight slider going to have problems when loaded to max? And if it is ok, what weight would be better at max load? 24? 26? Or at max load is it better to just leave stock?

Thank you

I have 26 gram Dr Pulley sliders in my 08 SWing. It's been converted to a trike which weighs 761 Lbs according to Motor Trike. I've had good luck with them. I haven't tried different weights because these worked for me. With the trike kit I've only lost 4-5 mpg on the highway. It still have good pickup and handling. I didn't go through the hassle of before and after testing. I just put them in and rode it. I've had them in before the trike kit was put on and liked the performance.

Although, the 761 extra Lbs isn't a suspension issue it does add to the overall get up and go so to speak.

Are these a "US" supplier option? I'm keen to play with just about anything....

Do you mean the trike kit? I believe so but not sure. They are made in Texas and shipped to a dealer to be installed. I ordered it from a dealer here in Minnesota. They in turn ordered it from Motor Trike after the finances were settled. It took about a month for them to get the kit and put it on. It cost me a total of about $8,000 to make, ship and have installed. I'm not sure if they ship overseas or not.

Hi Dale

I meant the variator pulleys and weights. I just bought one, I'm going to change the belt because whilst he said it had just been changed, he couldn't tell me the brand of belt fitted..Two birds, one brick is what I was thinking..

I changed my belt as soon as I bought it also.  It's best to know what you have and how old it is. My opinion, I'd go with a genuine Honda belt just to be on the safe side. I also change oil and filter with any vehicle I buy just for my peace of mind.

"Are these a "US" supplier option?"

Dr. Pulley is a Taiwan company so I'm sure industrious Chinese sellers have found their way to the UK.

I installed 24 gram sliders last week (you can also buy Dr. Pulley variator guides in a set of 4 to go with the sliders). The improvement in smoothness and power was immediate. Can't go wrong for the price.

I don't know how the sliders affect the load but I'd guess it might be an improvement, since they're changing gear ratios to give you more power, faster.

I'd be more concerned about the setting on the shocks. You can adjust the rear by hand. Setting #1 is for light loads. Setting #2 is standard. Setting #5 is for the heaviest loads. Just make sure the numbers are the same on each side (and don't pinch your fingers while turning ;o).

Going for lighter weight sliders is similar (but not the same) to lowering the gearing, it gives you more thrust at a given speed at the expense of higher revs.
Don't take this analogy too far though.
Me and the other half push the weight limit, 25g Dr P's give us a little more acceleration when we need it.
I do now get regular visits from the cvbelt light. I thinks that is just due to the ECU having a hissy fit at the disparity between engine and rear wheel speed been outside the expected parameters.

Iv'e had on order Dr.Pulley Sliding rollers SR2820/8-26 and Sliders from Dr. Pulley Tuning parts in Germany for over 3 weeks now and there still out of stock, the annoying thing is I have paid for them, so can't really get elsewhere

I installed 26g Dr Pulley rollers into a stock variator (the old ones were pretty spent!). I noticed a increase in acceleration riding solo but with pillion it was hardly noticeable and it's increased the RPM by about 300. At 70mph it runs at 5500rpm (previously 5200rpm) under all loads.

The other thing I did notice was a slight drop in acceleration when needing some grunt to overtake on motorways and open roads when loaded up but I still find it adequate. I found the 26g rollers a worthwhile addition.

So to bring the revs down for cruising, it needs to be the 24g rollers by the sound of it. Ok. Once I've got used to it I'll make a decision on that one.. I think it accelerates quite smartly as it is, I need to get familiar with it over the next few weeks.

You guys are the best! Thank you for all of your quick and informative answers. The knowledge base here is amazing! Thank you for giving me the information I was looking for so quickly. Based on the info here I will try the 26g sliders.. but I will wait till winter teardown to do it with a new Honda belt. Also planning to do all the fluids and replace a belly panel that was broken for me when I let someone ride it and they bottomed it out… It’s just to fun to hop on and ride for now to stop to fix “what aint broke”… But its never to early to start shopping for parts on rainy days..

The rise in RPM is due to using rollers instead of sliders. The sliders will drop your RPM at anything from 60 and above due to it's physical design. Your RPM will go up higher on starts giving faster starts. With sliders you get the bennefit of faster starts with a drop in RPM (500) at traveling speeds. I tried the 26g sliders to quiet the vibrations at start, in addition a more responsive throttle. Later I changed to 24g sliders for faster starts.

Ah. So I need sliders rather than rollers.. All good info..
