I notched mine to get a little more top speed, gained around 5 MPH...

It works ok but you realy need to make sure the ramps are good and smooth.I also have seen people drop a spot of liquid weld on the bottom so the rollers sits up higher for faster take off.

My ramps were smooth alright.. I had it milled in a machine shop

Also shave like 2mm off your drive boss and you will be doing real good.

I left the ramps alone and just took 1 mm off the outer wall and relieved the inner wall too.
(the yellow circled area). Then when I installed 16g sliders it would rev to 9000! I just added
1.5g to those sliders to try again...

With the outer walls completely gone I'd worry about the rollers turning sideways and jamming
up in there.

Wear the yellow is were I put some liquid weld so the rollers sit up higher that way they rolle up faster for faster take off. works good.

Wordslinger did one a while ago im sure and it seemed to work well till the variator broke where he had ground it down  :o
Suppose it all depends how much you take out.
Chaos is my co-pilot.

   when you shaved the variator, did you look at how high the belt came on the variator,. would there be any chance of the belt coming off,   and what is the RPM. at 60 mph. thanks for any info,.

Top speed... 

The belt was just about 2mm out the variator and I don't think it can come off, unless the belt can stretch...

What rpm at 60mph?.... sorry don't have a tach...


FYI... we do this just to experiment.... Stock is still safest...  ;)

did you take 1 mm. off the drive face and 1mm. off  the sliding face for the close shave,.  I measured the space between faces and it is 25 mm.  and I measured the belt it is 24 mm.  wide,  they are not up to spec.,the belts I have are 24 mm. each,  thats why I have higher RPM. than cortez,  spec. for belt is 1004 /  25.2 /  X 30 degree slope,.

   I like the downtown variator it has lots of meat on it,. to play with,.  I shaved 1/2 mm.  off of the two sides,. so my pulley is 24 mm. wide now,.  same as the belt ,.  I think I should take off an other mm.  I might get then same results you got ,.   took the variator to a machine shop and they did a half job,. I did the rest with my dremel,.  extended the ramp to the edge of the variator,. sure took a lot of sanding to smooth it out after,.  I took it for a ride after and at 6,000 rpm I was crusing at 70 mph., that was a first for this scoot,.  the only thing is,, it does not work under lower speeds,    has any one tryed over size rollers  I was thinking to get 23mm. 18 mm. 24 gram sliders and cut them down to 23/ 12   16 gram then adjust to suit after,.  what would be best for cutting   laser ,.  water jet,.  ????  any ideas welcome   de dee
