My 2005 PX150 has a delay when pressing the starter button most of the time since I got it. The delay is between 1 and 2 seconds between the time you press the button and the starter engages. I took the starter off and appart, cleaned the starter worm gear and greased it again (all good) and checked the brushes (look good, had some graphite grease in there and I put a drop of spline great on the pinion). I cleaned and grease the starter button (dialectric grease) = all nice NO CHANGE. Checked the clutch switch = OK. I tested the circuit while the starter motor was disconnected, and it sounded like there was no delay between the switch and the relay. NB: When starter connected, I do not hear the relay instantly followed but the delayed starter....so there might be some effect from the load of the starter motor.. but I did not test enough to conclude on this.

The scooter has 12,000km on it, but looks brand new (I think it was really babied by previous owner - friend got some with 1000km or less that looked like crap compared to mine)

I did not check the starter relay nor the anti-relay (as they translate it from Italian = safety unit to avoid starting while running). Not too stressed, but was under the impression that the delay got a bit worse this week.

Any ideas on what would cause this?

Hmmm...mine has a little bit of delay as well, but not a 2 second delay. I've also bypassed the clutch safety switch on two of them as well. I didn't notice any sort of delay after that mod.

sounds like the switch that sits behind the clutch lever and it activated when you pull the clutch in - to allow the circuit to engae. is sticking

I rarely use my electric starter, but with an old, low quality, and/or not fully charged battery, I get the delay, as well.
Last month, I put a new, fully charged battery in, and the starter had no delay at all; this has happened for the entire 35 years I have had the scooter. You might want to get your battery load tested for free at any auto parts store.
