Hello.
Has anybody any experience with running straight grooves compared to stock?
And if so would you recommend it ?

Some are actually straight grooved stock. Straight grooves can help to keep RPM more consistent. Some prefer the dual angle though. Also depends how it works with the variator.

I've tried a bunch of variants. Straight, curved top and also ones that have the straight groove but drop straight down at the end.
Favorite is straight angle from top to bottom. Holds RPMs consistently like 90 said.
Curved top hold my RPMs too high... past the powerband, and my wheelies suck.
The last one mentioned has consistent RPMs until just about top speed then they drop like crazy. Great for long trips, keeping the top speed cruising revs low, but not good for the style of riding I do.

That has the same grooves as the Naraku and our SSP-G adjustable clutch. They have one set of straight angle grooves, and another that drop straight down at the end (top speed RPM drop for cruising). I tested the SSP-G one, because I've only seen the grooves curve at the top, not the bottom.
WOT speed run down US19 and right when I got to 55mph the RPMs went from 7900 to 7000ish. It was nice, only if I was cruising far distance. I like to have more smooth, fluid like shifting of the CVT so I always run the straight groove.
Just yesterday I re-greased everything in there because I was getting some hanging up coming to a stop, like the clutch wasn't disengaging. After a clean/grease it was RIPPING and I had to put in heavier weights.

Cool man  I just got my hands on one. ( New Parts!!) I usually use wheel bearing grease and it seems to work okay, with minor leakage. What type of grease do you use? |

I also got my hands on some new clutch springs: Naraku 1000 rpm 1500 rpm 2000 rpm.
What do you think will pair well with a 15% stronger torque spring, and a aftermarket variator with 4,9 grams rollers?
its a 72cc, do you think 1500 rpm springs will be a push?
I just want a slightly racing'ish takeoff, but I of cause dont want the belt to move down in the pulley, before the clutch engages.

I would try the 1.5k first. I run around 6.5g with a 2k spring. As for the grease, right now I'm using a high-temp wheel bearing grease that is supposed to have a 600*F melting point but still gets thin and flings out a little. I've used teflon grease as well and that held up great for a while.

Ok cool.
Just so we clear, we are talking about the 3 small springs in the clutch right? Not the big one.

I like it the tightest, but my clutch is set up different man, my belt rides a little lower during idle, meaning the clutch spins faster and wants to engage sooner. So, I run the red 2k springs. If you had everything stock and put 2k in there it would have to rev so high to take off that stop-and-go traffic would be Hell. |

No worries
What do you think will be best for my setup ? 1000 or 1500 rpm naraku springs?
Will 1500 rpm springs be too hot, with 4,9 gr. rollers?
