The Honda PCX / Forza / ADV150 / SH Forums

At 13,800+ miles I now consider my PCX as near dangerous on dual carriage ways or fast A roads. I have to keep the throttle wide open all the time and only get an indicated 55mph (the reality is probably under 50mph). The result of this poor speed is following traffic gets frustrated and makes risky overtakes a common experience for me (cars trying to slip by dangerously when they wouldn't do normally, tailgating etc.)

The drive belt gets replaced at the 15000 mile service, but I think it should be done at the 12.5k service at the latest. I don't know if roller weights (?) get renewed or are just inspected.

An economic consequence of having the throttle pinned is I'm now only getting 96mpg on a run where before at similar speeds I could expect 120-125mpg

Might be worth slipping a new belt in yourself, its easy enough to do.
Rollers are £13.39 and a belt is £48.50 from AJ Sutton

Can't do links because Suttons webmaster has used back slashes.

You could just copy-paste the links into the text portion of the message if it won't let you use it in link part of the editor. Not sure why backslashes aren't allowed though, weird.

As for the belt, if you have an impact driver, it's really easy to change out. Your rollers shouldn't need surfaced, but the belt will definitely need replaced. My belt at half that mileage is already affecting top speed on my bike, I'm down to 58mph at wide open throttle now.

It's possible to grind down the center spacer between the two drive faces, but you'd have to be really careful to get the new spacer perfectly smooth, or you risk damaging the drivetrain.

Tried that and it resulted in broken links, however using the website differently has given links which seem to work:

Hello everyone. Long time no see.

Remember my old video I posted a couple months back?

My PCX had already slowed to 57mph top speed (pre J Costa variator) even at the 4800 mile mark (if you look closely you can see the mileage). It seems like the belts wear down quickly causing a decrease in top speed even at early miles. It seems disappointing that this would happen so soon. I am now at 8000 miles and it gets worse. My J Costa basically gets me now only to 61mph at its very best, when it used to get me 61mph to 64mph. I need to get a belt to see if this will indeed fix the problem. I would look for a bigger bike but money is tight right now. This is too bad considering there is a dealer in the area with new '09 Aprilia Sportcity 250's for $3900 after all taxes, fees, etc are taken into consideration.

There's a reason they're so cheap, they are very old tech and unreliable and you will wait an eternity for spares.

A How-to on how to replace that belt would be sweet.

this is amusing, i thought my bike was feeling a little sluggish so i ordered exactly what is suggested before i saw this post, fitted them last week and wow, what a difference. back up to its usual 63ish mph. when comparing the new to the old weights you could see flat spots on them and the belt had warn a lot too.
i actually leave my job in 2 weeks, i am thinking of buying a new set of tyres, belt and roller weights just in case

The belt gets a really hard time to be honest and 10 miles is the absolute maximum I would leave it It wears on the outside edge and lowers the gearing. As well as replacing the rollers I'd check the variatior faces for groves caused by doing a constant speed

Is this referring to with or without the J Costa variator? Also... The belt needs to be changed 10 miles? (or 10000)

If anything the JCosta will cause increased belt wear.

The extra few miles per hour from J.Costa is the only thing that has kept me from going insane due to gradual loss of power starting around 3500 mile mark as this bike is used intensively for travel (as I'm actually a home health nurse nowadays). The good thing is I have a spare belt from these guys.

They have the best OEM prices I have ever seen. And since the financing has fallen through on that Aprilia 250 from a couple weeks ago, I dodged a bullet in piss poor reliability and even higher general service prices and requirements than what Honda demands. Thanks to gn2 and some guy I net at my usual Honda dealership for steering me away from trying the Aprilia deal again in the future.

I just need to buy an impact wrench to change my belt, as I now am about 8200 miles and quickly rising. I put on the J. Costa by borrowing an impact wrench but I would prefer to buy my own soon. My rear tire has gone bald with all these miles! However, I have an appointment later this week to buy and have them put on.

Next I will buy a feeler gauge to attempt my own valve adjustment in about 3500 miles.
I hope that goes well.

I have some 2400 kms in my clock right now (some 1500 miles) and so far she's fine. When did you guys start noticing this loss of performance?.

Mine didn't become apparent till about 9,000 miles.

Oops 10k miles

i'm with gn2 here, i would say it was around the 10k mark i noticed. then after it's 12.5k service i had a look and spotted the hairline cracks a belt gets when wearing, compared it to the new and there was a huge difference in belt size, just bought a spare belt and rear tyre as i leave my current job on friday. no more cheap parts

Again, for me I started losing power around the 3500 mile mark. I guess I wasn't so lucky with my belt.

New drive belt and rollers fitted and now back to indicated 65mph

Nice one, where did you get the parts from and how much were they?

I just got the dealer to do it while I played with their CRF. The belt was £40 and the Roller set £11 + VAT
