The Honda PCX / Forza / ADV150 / SH Forums

Given the smaller 13" rear wheel, I would assume that you would need taller gearing (larger diameter Stock Variator) vs the 14" rear wheel with the older models. That would explain why the older model Variators lower the top speed.... Like emax22 said. , 127mm, vs the pre 2021 120mm Mon-Ey...

Ahhh I see what you did to modify the stock driveface.. lol Didn't even notice at first. So my idea behind the belt being too short is that if its too short, the belt is not riding all the way to the edge of the Driveface.. Use a Sharpie Marker and mark up the faces and then go run it. Post some pic...

I wonder if you have to run a longer belt in order to take advantage of the Polini Variator. Maybe Polini sells a Polini belt to compliment it.

I have a question. Which one is Stock and which one is Polini? Im guessing Left is Polini?

Is that 130km/h on a big bore or stock bore?

Its a small light scooter. If you are trying to ride 50mph+ majority of the you probably got the wrong size scooter.

a 250cc+ is what you need.

Surly though the polini kit should just work out the box and be fully optimised for the best top speed capable with the power the pcx has and the rollers and contra spring being optimised to keep the engine spinning around the 6.5k ish rpm Mark. I been tuning scooters for 15+ years and nothing real...

I run 10.25G Dr Pulley sliders in my NCY Variator. (61.5G total) I would say run the stock contra Spring and run the 10G rollers in the Polini. If you get your top speed back, but you lose acceleration what you can start to do is lighten 4 roller weights at a time. 0.5g from 4 rollers. until you reg...

Going to 8 weights as opposed to 6 like the stock Variator, you will have to go for non- OEM size weights. If you run 10g weights that's: 80G total If stock is 14g that is: 84g total in 6 weights... If that Contra spring is stiffer than stock, you need to go even heavier than stock. Chances are you ...

I see that the linked article said the clutch type was “Wet, multiplate slipper/assist”, which is obviously incorrect. When I see inaccuracies such as that it makes me question the rest of the article. That was the first thing I noticed. Start to lose credibility. I really don't like the different ...

I dont believe any ABS system is speed dependant. It's usually activated when the front wheel is spinning slower (slipping) than the rear wheel where the speedometer senser is located. You can be going 10mph and you do a hard brake and the front wheel started to lock up which is when the ABS will pu...

Just saw that post. Sorry to read about that. Good luck.

Throw new rollers in. Have you tried that yet?

Im sure they work just fine. Install them and let us know what you find out.

Personally, I stick to what i know (Dr Pulley) that last thousands of miles. I have around 5k on my current weights still look new very little wear.

Are you talking about a flashlight?

You don't have to change the #8 (Final Gear) as well to compensate for the larger diameter of the #6 gear??

Also, Maybe some lighter weights so the engine spools up faster? 17g seems very heavy.

What kind of gains do you get from a 14t? I only ask because if its not that major, just swap back.
Im guessing you changed #6 ?

I run 120/70 Front tire. Rides great..

When the rear is done, put a 140/70 in the rear.

Once you start to add stuff like amplifiers for sound systems and stuff like that you might to start having issues. But heated grips and vest is no problem.

I would still recommend if possible to keep it on a tender as much as possible. Keep that Battery nice and healthy.

No issues with that at all. I have a 65watt headed jacket and it doesn't even notice it when its plugged in.

An old thread, but still current. My clutch bearing has been an issue since buying my 2012 PCX150 from the first owner in 2016 (bought in 2014) with only 134kms on the clock (his wife had plans to ride to work on the freeway, but soon changed her mind). The noise is now so bad (while pushing and id...
