I might try that eventually, but yeah, basically I'm trying to get the engine to rev a bit more at a given speed so it doesn't lug itself. Just that the clutch can't handle it at lower speeds lol

Made engine adjustments probably? I wouldn't go that far, unless i actually had an entire service center's worth of tools and equipment with me, as well as a second bike

Thanks for the info, but yeah, the shudders started as soon as i dropped roller weights and kept all others stock. The current setup works fine but the roller weights actually ended up being too heavy (probably because of the pulley), almost like having 16 or 17 grams on the stock pulley (15 is stock) I appreciate it though, i might just end up going the easy way and slapping higher rated clutch springs so it fully engages at speeds that no longer slips.

I do know what the problem is, I'm just trying to find if people had actually solved the issue of the trans allowing for more torque than what the clutch could effectively transfer at low speed. Basically matching the engine speed at low speed to the capacity of the clutch by finding the right combinations, it'll eventually show itself, but asking at a forum is much easier lol. Also stock is mostly fine, especially for relatively flat and open areas. But for my use case, which necessitates frequent stops and a sudden steep ascents and long stretches with shallow gradients, I'd prefer a more prompt 0-50 rather than the stretched out acceleration of the stock config, as well as a bit more revs to hold the speed steady rather than lugging it and needing to pump the throttle often. The stock config would definitely be ok, I'm just trying to find my ideal configuration that doesn't necessitate constant 50% throttle. Top speed is also not too important for me, others tinker with the cvt to eke out more top speed, bit I'd be fine if it tops out at 90 if it could reach it sooner. 80 is the legal limit lol. I do realize that a more powerful motorcycle or a manual transmission would solve my problems, but yeah it is what it is

I am often very gentle on the throttle, but i do want better take off rather than just slipping the clutch and lugging the engine on uphills so i changed some parts of the cvt, particularly the roller weights (15-14 grams). Now the whole scoot shudders when feathering the throttle at 8-11 kph. I switched back to stock configuration and the shudder is gone, now it just slips way too much at takeoff. Currently i have the ncy variator w/ 14 grams as well as ncy clutch with 800rpm clutch spring and contra spring, the shudder is there but it is not very noticeable, but the gearing feels too high for hills so i intend to either increase the contra spring rate or decrease variator weight. I had the feeling that the shudder is because the engine is quite torquey at low rpms, and that same torque is wasted on clutch slip hence the reason why I'm changing parts Any ideas how i can switch to lower variator weights without having shudders?
