Did not make a difference w/ papa's YNSX.

Just as slow.

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.

Just back from time trials before and after variator mod.

No difference.

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.

Or using your methods you could simply have added an extra washer rather than machining the pulley halves.????

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.

So Malossi is 13° but for which scooter.?

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.

U do 

shipping too?

 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 ;-))))

First, you can change the fuel level sensor.

The original sensor for Honda Dream has a crazy price -37080-KFM-900 / UNIT SET FUEL DREAM ฿ 1.400
Come to the parts store and show this number and say "COPY", the cost of a non-original part is 80-110 THB and works great. You need to remove the right body cover for replacement.
If the problem is not resolved:
37200-KFM-901 SPEEDOMETER ASSY DREAM ฿ 2.290 +/- or maybe 37200-GBG-T10 for model with indication of 4 gears.
37200-GN5-731 SPEEDOMETER ASSY DREAM for neutral and top gear indication only.
 The cost of the non-original SPEEDOMETER ASSY DREAM part is 500-700 THB, but it's may work not stable.
Working time is 20-30 minutes only.

WBR,

The 175 looks pretty good for those who want a cheap reliable retro bike . That's an insane jump in price from the 175 to the 250 though. Wonder what the reason is?

different rates custom duties only

W 175 & W 175SE - made in Indonesia 

W 250 -  made in Japan
