well for 2 1/2 years ive been trying to get this cvtech to work right, ive tried different weights on pri. ive tried reclocking the driven and it just wont work the way it should, could not get it to down shift when pulling a hill it would want to upshift and smoke a belt, if i played around with the throttle i could get it to cooperate for about 2 seconds and thats it....soooo i even tried going to a 1190 comet hooked to the cvtech driven, same thing P.O.S. SO I FINALLY PUT THE 780 DRIVEN WITH A RED SPRING IN IT AND THAT MADE ALL THE DIFFERENCE, WOW..so when comparing i noticed that the problem with the cvtech is the ramping of the helix, its too quick and theirs no fine tuning of clutch when in different loaded ranges...notice the pics of the cvtech and 780 comet ramp angle, i marked the cvtech with a marker so you can see the angle
