First time in my life, when changing the angle of half-pulleys acceleration does not change explicitly. When adjusting CVT, I always use a tachometer to be sure of the result.

Mech replaced the half-pulleys only? Was the torque driver disassembled with cleaning and put new grease? Torque driver running affects acceleration too. I am confused very low roller weight relative to the standard for a noticeable increase acceleration. I would change the belt for a new one when working with the CVT.

You forgot about the changed half-pulley angles, this is important. ???????? With the changed angles of the half-pulleys, the belt is pushed out to the outer radius more slowly.

Comments for N-MAX and Freego - the new Freego had vibration at the start, especially terrible at the start uphill. I disassembled the CVT and saw abrasions from belt slippage at a distance of 2 cm on both half-pulleys. The belt did not come into contact with the bushing as it should be. As far as I understand, Yamaha made a reserve to compensate for the full wearout of the belt from 22 mm to 20 mm. But with such settings, you should always ride only on a completely wearout belt ???? 13 ° for a movable half-pulley and 12.5 ° for a fixed , in my case will increase the gap by 1,5 mm and the belt goes down to the bushing, not reaching 4 mm. There is no vibration or slippage and there is a reserve for belt wear. As the belt wears down, you can simply remove the washer between the bushing and the fixed half pulley to compensate for the wear if it needed. This is my personal experience only.

Malossi vario for N-Max 150 have angle - 13° for a movable half-pulley and 12.5° for a fixed. OK for Yamaha Freego and many Yamaha's model toо. Big Honda CNX guys use the same angles for the PCX 150.

I made this modification for all my bikes and for friends who live near me. If you don't have access to a lathe, I can buy new original pulleys, modify them and send them by TH EMS. Send me PM with the bike model and the year production and I will reply the final cost. Overcharge 60 THB - the cost of a cup of coffee while I'm waiting for the turner to complete the work ???? It's not difficult for me, let's consider this a hobby, not a business :))

200 THB and 15 minutes for both half-pulleys. Works like the Malossi kit, but the cost is different ... And there are no crazy customs and delivery payments ;) Angle of the half-pulleys is the same as Malossi.

Takeoff shudder can occurs due to belt slippage on the variator pulleys, not only clutch slippage and torque driver belt slippage. This can be seen by the scuffs on the pulleys. Modified pulleys 13° for a movable half-pulley and 12.5° for a fixed remove this problem.

With modified pulleys, you already have higher RPM than with stock pulleys. When I move to the mountains I lighten the rollers weights by 1 gram, which increases the RPM by 500 - 550 +/- at the same speed. Under normal conditions, acceleration with modified pulleys and standard rollers weights is enough for me. Don't forget about more hard torque driver spring and also about the reinforced clutch pads. There is no limit to perfection ))

Also you can use the Yamaha N-Max 150 clutch 2DP-WE622-00 - boots only 2DP-E6220-00 - clutch assy Welcome to Yamaha Shop ;-)

I had the same problem with PCX 125 2011 and Yamaha FreeGo 125 2020. The simplest and most effective is a more hard torque driver spring and changing the angle of the variator - 13° for a movable half-pulley and 12.5° for a fixed. The cost of work in CNX mechanical workshop is 200 THB and 15 minutes. Roller weights left as standard, or 1.0 - 1.5 grams lighter, for different conditions. No problem anymore ;) You can replace the clutch pads more larger - in the photo on the right the standard clutch. Honda PCX 125 - 150, Honda Vario (Click) 125 - 150, Yamaha N-Max, Yamaha FreeGo, etc have same clutch. All recommendations are only based on my experience and common sense ;-))))
