thank you so much, for such a esplendid video. i would like to ask you a question. can i make myself the rubber seals of this piston? i am having trouble to find them where i live in madrid.
omkar om No. You need to buy them, look for another master cylinder to remove the parts from, or swap out the entire master cylinder. Thanks For Watching!
Do you still have a scooter? Are the sliders worth the 2-3x the price of roller weights? Also I was thinking of using a dry film lube in the variator, in the roller/back plate , is that a good idea? I'm thinking about venting the cover also, the other scoot I had, I could smell the hot belt at times, for now it runs well, it does 0-25mph up grade fairly quickly, I'm expecting about 55, on flat land, it's close to where I want it, (you can only get so much from stock 139qmb cases) I am thinking about swapping to a 150cc, 157qmj, with head work, and maybe a big bore, 171cc or so, I doubt I'll get over 100mpg with it though, although a 232cc stroker would be nice, it would be hard to descuise it as a 50cc! Haha, with the big bore, and cam, it doesn't sound like a 50! It still needs carb tuning, it is running rich, I think a needle adjustment will help it.. I figured I would need larger jets, with the 20mm carb, and no stock filter box, I think 1-2 sizes smaller will do it if the needle doesn't! I think sliders with the performance moving side and ramp plate, I think it allows for more movement, ( making a larger pulley on top end) it seems sliders will push out further than the rollers! The back half of the variator is available coated for less wear of the rollers, I think a dry lube will do about the same, a Teflon or ceramic coating, or moly or carbon powder, I'll look at what others are doing, great videos!
This is a very good and instructive video. Easy to understand with great video and instruction.

If you want, apply a VERY light coating of graphite powder for locks, on the sliders before installing them. That's what I did.
Thanks

I like to use small zip ties to get o-rings/seals I wanna reuse. Less chance nicking/cutting them.
Whatever works. :-) Thanks for watching!
Does anyone know the screw type/name for the screws on top of the master cylinder? Many thanks in advance!
You can buy new screws for the master cylinder cover at any hardware store.
I have no brake handle at all thinking need new pads no resistance at handle at all
76chyanne Maybe the fluid leaked out.
Questions are from years ago, are you still available for questions?
Yes, just keep them short.
No compression after bleeding rear brake, master cylnder empty?
