Now i have tried every fuel e20 91 green 95 the lot,When on a long straight road i open the throttle when traveling at a speed it keeps pulling.As the bike is fairly new got 4000 service due,i know it must be the fuel ,the bike has been doing for a while so ,it cannot be water in the fuel flushed the system out already,any ideas thanks andy

QUESTION RE BRAKES: I haven't changed the brake pads or rear shoes yet. Can anyone advise how many kms those items usually last?

Thanks[/p]

MY 1 year old PCX with 22,000 km that i ride hard and brake even harder shows little or no wear to the brake pads.

I went through my first rear tire ar 20,000 km (8000 Bt for new) and would guess I have 3000 more km on the front tire

It's indeed true that Honda is using special, more and smaller holes, for the PGM-FI (fuel-injection) system. The holes in the injector are a few microns smaller than the average regular fuel-injection system, the biggest advantage is the production of smaller fuel droplets in the combustion chamber of air/fuel mixture. The much finer/smaller droplets ignite and burn much more efficient than bigger fuel-droplets.

The advantage of better combustion is of course better fuel efficiency and more performance.

The downside to smaller holes in the injection-needles is that dirt particles can block fuel flow more easily.... (Thailand, especially some of the no-name petrol stations up-country are not taking the filtering of the fuel very serious.)

I strongly recommend that people using a Honda motorcycle or scooter with PGM-FI install a good fuel filter. It will seriously help your motorcycle.

You need to be a bit careful with filters in the fuel-line of your fuel-injection scooter, Because the fuel-line of a fuel-injection scooter or motorcycle is under pressure you should also ONLY used fuel-filters that work with the pressure requirement (41 to 44 PSI).

are the Honda fuel filters not as good as you can get else where,just would like to know

Reporting on my surging problem as promised: late but I'm here!

I took the bike in last week and they replaced the drive belt. That took care of part of the surging, but I still have something happening in the background at a lower level. I'll be taking it back in next week.

To recap: I had moderate surging at 30 to 40kms/h. A drive belt change reduced the surging but didn't cure it. It is at a lower level now, so it looks like there were two issues causing the problem.

I let you know what happens after next week.

thanks please let me know,mine happens over 100kph ,it must be the injectors like thai design said with mine

Hello andyc

I haven't taken it back in yet for the fuel injection, but I have a comment about your "over 100kph" surging.

My PCX has always had that issue at the top end and I wonder if it is not the result of some engine surging, but is instead a function of the speed governor and you're mistaking it for a fuel problem. As I understand it, the PCX has an artificial limit on the top speed. Mine is 108kph and it won't go faster than that even downhill full throttle with the wind behind, proper pressure in the tires, light load and the driver bent over to minimize the wind. 108kph is it. The bike will come up to that speed and then slightly back off, then push back, then repeat. It's always done that.

I'm not saying that your problem couldn't be fuel flow or something else, but could what you describe be hitting the speed limit wall?

Thats what honda said to me,but what i didnt understand when i bought it it could the 120 now only just over the 100kph,i just didnt trust what honda were saying to me,maybe its correct then,thanks

I am writing this because i think the Honda pcx has a problem in Thailaind,Why when my bike was new i could reach the 120kph but now i get the pulling at over 100 kph,Honda are now telling all there customers its the speed management system or other things to those words,I have stripped down my fuel filter i have check the injecters the bike cannot cope with the fuel here in Thailand that is my own personal view,as other people have stated the injectors are made smaller on the pcx ,fuel is not clean and that includes the big name pumps but i will not state which one on this site unless i get a email,I think honda are pulling a fast one here otherwise there could be a recall in motion soon.
