Just changed from 26g sliders to 22g Sliders. Wow!

Today I finally got my bike in to install my HyperPro springs and while it was in I also had them install a set of 22g Dr. Pulley Sliders. (I was running a set of 26g sliders before) All I can say is Wow!! When I crack the throttle my rpms jump right to 5500 and it pulls really strong. This is very close to the same acceleration as I had with the J Costa variator. Close enough that I really can't say that there is any difference. The big difference is that at cruising speeds - 60 to 70 mph - my rpms are much lower with the 22g sliders than I had with the J Costa. With the J Costa my rpms were about 5100 at 60 mph and about 5700 at 70 mph. With the 22g sliders my rpms are 4600 at 60 mph and just a hair over 5000 at 70 mph. I will monitor my gas consumption over the next few tanks, but so far it does not seem like my gas mileage has suffered like it did with the J Costa. I think I am still getting somewhere between 54 to 58 mpg. With the J Costa my mpg had dropped to around 42 mpg. This is sweet!

I am curious how you selected 22g versus a slightly lower 24g??

Will you be testing with 1/2 22g and 1/2 26g averaging to 24g ... or just staying with the 22g??

I went with the 22 g sliders because they were in stock and I thought that they may work better at my elevation. My bike does not produce as much horse power or torque as it would at sea level and I thought the lighter sliders would give me a bit more boost. I am very pleased with the performance with the 22 g sliders, but the big question is how will they affect my gas mileage. At this point I plan to run the 22 g sliders for a while and monitor my gas mileage to see how it does. I am willing to accept a bit of a hit on my mpg as a trade off for the quicker acceleration, but I would still like to get at least 50 mpg. If my gas mileage drops to less than 50 mpg, then I may look at trying the 24 g sliders. I do not plan to mix different weight sliders.

Have you noticed any hit to acceleration out of a turn, or overtaking speed on the highway? I recently switched to 26g and I feel like I lost pickup in both of those situations. Not a lot mind you, but some.

It seems to me that the 22's would take even more of a hit.

Aidan:
No. Just the opposite. As soon as I give it some throttle the engine revs above 5000 rpms and it takes off with a nice snap.

Here's a thought for you. Our bikes are different, but similar enough that you may find this will work on your Silverwing.

I made the mistake of installing my DPS weights the wrong way once. While I did "goof up" on the installation — the results were incredible!

I had used the DPS weights for awhile and put them in wrong one night without realizing it. I went to merge onto the freeway the next morning, and couldn't believe what happened. I twisted the throttle and my head jerked back. (Yes, this is on a 400cc scooter!) The rpms jumped immediately to about 7000 and began to climb rapidly. Then the CVT "shifted", which was the DPS weights moving to another face. The rpms dropped to about 6500 and began once again to climb really fast to about 8000...and unfortunately, I was gaining too quickly on the traffic and had no room to keep accelerating.

I had the biggest grin on my face. I didn't know what I'd done...but I liked it!

Here's what they looked like installed "wrong".



Here's what they look like installed correctly with the groove at the top of the DPS weight.


The pluses:
- It was like adding another 100ccs to the bike. The power was instantaneous.

The cons:
- The power was instantaneous. I wanted to use it, and this was not a good idea. I knew I'd end up with a "performance award" from the Washington State Patrol very quickly.
- The rpms would jump at the slightest increase in engine load, whether from twisting the throttle...or simply head winds or road grade. The rpm jump was absolutely smooth though. If I didn't have a tach in front of me, I'd have a hard time knowing it.

So I offer that experience as something that a few of you might wish to experiment with. Just don't blame any performance awards on me!
