I am going to go with 16gr sliders on the MC54B. Anybody have any experience on that?

I can't remember if I tried all 16's but I did try 4 16's and 4 14's, and it bogged pretty bad on the low end.

So I tried 4 12's and 4 14's, and it was really high in RPM's, but wouldn't give any top end.

Now I have 4 16's and 4 12's for optimum top end, even though I would like a little more torque on the low end, but it is the best of the arrangements tried.

I would reccomend all 14's if you don't want to buy $150 worth of sliders, but if you do, you'll have a lifetime supply. I think the next time I go into the variator I'll try all 14's. Right now we've got 2 54B's running with the 12/16 combo, and they are satisfactory.

OK, thanks. Good to know.

I don't know how accurate it is but I thought I read somewhere that someone said the 250B came with 14's from the factory. Is that right, do you know?

Mine both had 16's, but I think JR's had 14's, so you'll have to weigh yours to be sure.

They're all 20 x 12, and after you clean out the grease, I think you can dispense with the grease cover. I kept mine on with both, but only cleaned out the grease from one, and left the other greasy.
Someone asked about that earlier, but I don't know if we got a definitive answer, so I'll try it without the grease cover, which would make the variator weigh less overall, and that may add a little torque.

I have the 54B and I use 12 g Dr Pulley sliders and had no problem at all with take and with top end speed. Once you clean out all that greese you will enjoy the sliders. BTW I weigh 180 and 12g work fine on my scoot.

Ce, I believe JR uses 12 gram sliders as well. He suggested them to me.
