Re: my pcx stalls when I open the throttle(once a time per 2

so you have something like "misfire" or a hesitation, right? when you twist the throttle you feel that the engine will stall but if you twist more throttle, you "save" it.. I haven't find the solution completely yet... few days ago I changed the TPS (throttle positiion sensor) I...

Re: my pcx stalls when I open the throttle(once a time per 2

mine does that too once in awhile :) probably once in every 200-300 km. though it does not stall completely, it is like when i start twisting the throttle from the stop, the engine stops revving for a very short moment, and if i continue giving it some gas it starts again without me having to start ...

Re: Noise from engine at 50 mph

Generally on the PCX, some slight shuddering at certain RPM ranges occurs due to the belt slipping on the variator. My PCX did it with the stock variator, and an aftermarket one. I get slight shuddering from somewhere around 15-25mph for about 2 or 3 seconds during acceleration. The noise doesn't c...

Re: Noise from engine at 50 mph

ok, so after talking with a few experienced folks i kinda came to a conclusion that this is most probably tires out of balance. I wanna try using ceramic beads (so far only found dyna bead on the internet, not sure if there are other brands) as an alternative way of balancing the tire since it is di...

Usualy starts at 40 km/h when u can physicaly feel it and the frequence is rising till after ...

Re: Having a weird scratching noise when driving with passen

Thanx for the welcoming everyone :) I live on Koh Samui by the way. I have asked a few people here on the island and they said they have it too once in a while, they would refer it to some flaw in design of the first pcx generation. The sound would be impossible to record, since it goes more like a ...

The only problem remains is the weird scratching sound from inside the bike when there is a passenger at the back (im 80 and she is 50...
