Variator

[zombie]

'Truth about rollers is you can compare them to performance "hi lift" cams. They start out taller than the roller= finishes it's travel taller than a roller. Their design shape was necessary to achieve that height, NOT because that shape moves better inside the var."


That was supposed to say Truth about Sliders...

So I take it that some of you use Dr Pulley sliders in your Malossi variators? 

The post above this one. I'm trying them.

this is based on my experience. A big diff on accelaration an plus 5-10kph on top speed. Even on the stock pulley. Sliders perform better than rollers have used then on may Gv 250 and super8 125.

And this is whit the same weight sliders/rollers?

[drifter]

will check grams but as far as i remember it's same as stock or just over or less 1gram.  my target for my x500 is to reach 190kph on the speedo. Lol. Maybe with a lighter rider it could do that.

Well if that's all you want - adjust the speedo using a speedo-healer.

So you can use Dr P's in a malossi variator? I have a new set of Dr P's, 31 gram I think waiting to be used. Had them in the stock variator for about 1500 miles when variator locked up. Put in stock thinking Dr P's may have been problem? But they are not, it's just that the stock variator is crap.

Yes you can Sissy! Use them at will.
Most Vars. are made of the same alloys. The BIG difference is in the "ramp" angle. It is another tuning realm completely, and unto itself. You may find rollers work for you or sliders may suit you better.
Figure what you WANT the scoot to do, and follow that trail.
Soooooo... What do you desire?

my sliders are the same weight with the stock rollers. there is a new product on the market called flying rollers. was inquiring about them and they said that they saw my complains regarding the sliders and that they would send me the flying rollers for testing and it's for free.

About all I do is tour. I don't care about o-60 speeds, if my bike will do 115 MPG & such. I would like to lowwer the RPM's at freeway speeds by about 500 RPM's. I don't know if the Dr P's will do this or not? Keep us up-dated on these new type of sliders. I have never heard of them before? Pink Yes

Dr pulley will give you some confusing results here. They raise the Var quicker giving a slower feel until you apply throttle. Once you start applying they will increase the climb rate. So you wind up going faster to feel them working. So if you want better performance, and lower rpm's go (2)gr heavier than stock (sliders). That should keep the stock throttle feel, and change the torque curve at both top, and bottom end. If the idea of more throttle worries you then use rollers (1) gr heavier. One gram per roller = roughly 500 rpm. This applies across the board from take off thru top end. It will all be lower revs. I posted else where that the engine does NOT control the cvt. It merely sets it in motion. The cvt does control the engine. What you want out of the engine is set in the tuning of the cvt... Stiffer control spring= longer hold on higher gear. heavier rollers= less rpm.

Thanks, 1 gram=500 RPM is good to know. I would like to set my freeway RPM's as close as I can to the maximum tourque level of the engine. So lowwering the RPM's about 500 or so would be nice. Are the RPM's of the stock variator the same at freeway speeds as with the melossi variator? What is the stock weight of the Malossi rollers? 

[drifter]

i use 31g for the stock pulley 1 gram heavier than stock and 20g for the malossi same as the stock rollers. sliders rev higher or quicker off the line  but have lower rpms on highway/top speed.

Drifter has a good formula, and I would try the rollers that come w/ the Malossi Var. (ask the dealer for the weight).
The reason I suggest "try" them is w/ new ramp angles you don't know where the cruise rpm will be. New parts have new effects.
Just keep in mind (1) gram heavier = 500 rpm lower rpm at same speed.
If your dealer is a knowledgeable guy he may know what weight to include to meet "your" goal rpm. He will need to know what weight rollers you have now/what rpm you cruise at. Then knowing the Malossi he can "tune" it for you. Not too many know them tho. Most just sell.
You may end up buying 1 more set of rollers/sliders to get it "nailed". Sounds like a hassle but it's really quite easy to do.
Most Utubers show how to swap rollers in under 5 minutes>

Yes, that's why I am asking these questions as they sell only. Meaning they don't know anything about variators, or anything else for that matter? I have a new set of 31gr Dr Pulley's. I think I may use the stock roller's in the malossi, (when I can afford it). And then change to the Dr P's if I feel the RPM's are to high.
