The Honda PCX / Forza / ADV150 / SH Forums

After some other project, personal problems and wintertime i've finally found time to change out the fuel pump, and.........
YES!!!!, Problem solved ! bike rides like a charm again, finally after all these months i'm enjoying my PCX again.

DAB wrote:Could it be that the fuel tank is not venting, Still would have the coil checked as the problem occurs when the engine is warm.

Thanks DAB, i will do this when the fuel pump doesn't fix the problem.

The spark plug's colour is o.k, i have tried to measure the ignition coil, but my Fluke won't let me...

I will replace the fuel pump as soon as it arrives the following days.

iceman wrote:As you say when warmed up, could be the air temp sensor (this is seperate from the TPS)

Iceman, i think the TPS assy holds 3 sensors including the air temp. sensor, i already replaced it.

You say stuttering at constant speed, is this any speed? When you inspected the belt did you take any measurements or just a visual check?. Has your maximum speed decreased? It stutters at any speed, mostly when engine is warmed up, i've checked and measured the belt, within limits, maximum speed d...

Checked belt and rollers, bypassed side stand switch, changed spark plug, still no luck...., i also cleaned out de VS sensor, no test ride made yet. I didn't check the TPS yet Fish, i want to start with the easy stuff before taking all the plastic off ( again :( ) Is this the original belt. what do...

So, finally got the parts from Thailand, changed the TPS, did a TPS reset and made a testride, at first i thought the problem was fixed but when the bike warmed up the same thing happend again, stuttering at constant speeds......... :oops: :oops: , could this kind of symptoms come from the drivetra...

I had a recall from the local HONDA dealer, the LED control unit had to be replaced, so i thought that this was the best oportunity to let them take care of the problem. When i got the bike back, the LED unit was replaced but they couldn't find the fault, the simple reply from the mechanic was: ther...

I think that if it was the TPS you would notice some hesitation on acceleration and jerking. At constant level speed perhaps fuel delivery and perhaps coil failure if so equipped on this scoot. Did this first come to light immediately after the valve adjustment ? No, it started before valve adjustm...

Update after my holiday: Read the fault code with the DTC, it said code 1-2 MAP sensor high voltage, followed the troubleshoot guide, all ok. Reset the DTC, fault still present with no mil indications....then i checked the TPS while this is housed in the same sensor and noticed that the resistance f...

To me it sounds like bad sparking break down, the dia tool would be nice to have so you could see real time reading while you are running. It sounds like the crank sensor is failing and would be what I would look at. If the tps was bad you would see it's values bounce when steady throttle is appile...

Hi guy's, I was wondering if somebodybody could help me out?, since a few weeks i'm noticing a stuttering in the engine at constant speeds, it feels the same as the rev. limiter kicking in but less. Things i've done so far: - Valve adjustment. - Replaced igniter. - Cleaned IACV connector. - Replaced...

Mel, it's the mid sized one, i don't want to drive with the large screen as a sail boat , thanks for the link for the spoiler, think i'm going to try that.

Hi all, Just mounted a Givi D1136ST screen on my PCX and went for a test ride, i was expecting less windforce on my chest and less noise around my helmet but during the ride i noticed wind turbulance some 55" behind the screen, just in front of my chest :cry: untill some 35" behind the scr...

Hi Mel, I've spent a lot of time on simulator training for the C-130 in Tampa, the hotel we've used to stay was next to the the laser spine institute, i saw people in wheelchairs in the morning and walking during the happy hour after they went for a treatment there. You might know that dutch people ...

Overall a very positive review and thumbs up! the only thing he mentioned as a area of concern is the fact you can't put a european sized foot anywhere, there's not enough space around the shifters.
In summary this is the perfect urban bike.

Cheers, Ronald.
