Hello, I have ps125 '07. I want to install additional lights preferable neon. Can you help in that?
Also I want to fit a switch to switch off the headlight if I want.

Third but most tricky question : is it possible to trick the brake sensor to make it pushstart the scooter ? I mean an additional circul so system would think the brake is pulled when in the reality it hasnt.

I hope this makes sense.
Thanks a lot

Yes, all you want to do can be done, the lights are the easiest because you have several ways to do that. One is go straight from the battery to a OFF/ON switch or you can splice into the wire that your existing lights function off.

The OFF/ON light switch may be a little tricky it all depends on how your scoot is wired, but should not be difficult.

I question why you do not want to squeeze the brakes to start the motor though that is a safety feature so if for some reason the throttle goes wide open when the motor starts you are holding the brake. But here again it would not be difficult to have the SOLENOID energized all the time and just require a push of the start button.

Would you happen to have a WIRING DIAGRAM for your scoot that would help you a lot. Also I hope your somewhat mechanically inclined otherwise you may mess things up with the electrics.

Thanks!

Great! I am so blessed to find this website! And I am very thankful already for the help. Seriously.

Few issues to start with: the official wiring diagram, service manual. These are on my list but I could find it. Even that here in UK this scooter is one of the best seller. Bit confusing.

Yes I have some technical knowledge and have a more skilled friend as well. Plus I want to do it badly

I had the idea about to dodging the safety features when I was fixing the brake. There is a little switch or sensor to feel is the brake squeezed. If is squeezed then this swith on the brake lights. I was thinking to do sometrick so in case of emergency when the battery dead I can push the bike to start. Otherwise obviously I would hold the brake when I start the engine.
Plus if I can twist this and send a signal like the brake not squeezed even if yes than nobody would be able to start the scoot.

That would be a great safety feature agains thieves.

Ride safe

Pushing the bike to start will not work. The Clutch has to be engaged for it to turn the wheel so without the clutch engaging the rear wheel is FREE WHEELING and will not turn the motor over. You need to use the KICKSTARTER when you have a DEAD battery,IF YOUR CDI is AC fired. IF your CDI is DC fired you have no KICKSTARTER and a battery is needed to start the motor. So if your scoot has a DC CDI a BATTERY IS NEEDED to start.

I am not sure is it AC or DC I will check that later.
What I figured out is if I push the bike and I reach 15 m/h then the cloutch will engage so that problem is solved. We will see.

You told me many new things again I need to educate myself to have a reasonable conversation otherwise just pointless to waste your time.
But till that point, thanks again.

[robster]

Yes, you were right about the push start. The clutch dis-engage at the speed of 15 but if I start from zero even I made it over 20 m/h still the clutch hasn't engaged. So this out of question.

Sorry for the delay but I almost sold the bike and I am very busy didn't have the chance to do my homework.
I will get back to you if I have any news. Thanks again

Hello, I know it's been a long time ...

I finally made some modification. I first tried to wrap it but after I talked few pro decided that doesn't worth.
So I just sprayed the front parts. I think its pretty cool. Matte paint. If I want I can post some pics.

I need to get some new bolts as they got worn but looks better. I bought a belly panel and the footrest panel, I will fit them shortly as well. 
I also had to replace the rear shock abs. Expensive s**t. 

Last year I left the bike in the parking lot. Was a very hot, sunny day. The bike didn't start. Lights goes off but then just some bad noise. Check battery, connections. After a while I moved to the shade wait 5 minutes and the bike started. Any idea about this? Since then I haven't experienced this issue. Just after heavy rain.

Yes, I had the same problem few days ago after a very heavy rain. I checked the battery, connections, I cleaned the connections, but nothing. Battery charged bike doesn't start. Left it like that. Next day bike started. No problem at all.

Not sure what was that.

The latest problem. Bike starts, rides, but sometimes even I am just on half speed I can't accelerate , and then I feel I am losing power F1 flash goes off and bike goes or sometimes goes idle and but doesn't cut. Sometimes after a while cut off as well. But if I stopes and start again, always for the first attempt the scoot is running like nothing happened.

Battery checked charged plus its a 5 months old one. I am using the bike almost every day.
I changed the sparking thingie, was a bit smokey, but the gap I guess was okay.
I checked the oil level. Was good, but I changed that one as well. I made already 2100 miles so its about time.

DESPITE all of these I experience the problems.
One more thing: few times I let it go the throttle and the bike was riding same speed like its stacked but then I moved a bit and was fine.

please guys help me if you know anything related to my problem.

Many thanks! Enjoy your ride!

I have a ps125 '57 27000miles in the clock.

Sounds like it's time for a carb adjustment, smokey equals too rich.

update: could that all this happened because of a faulty battery? Today the bike hasn't even started try to charge the battery nothing...

[robster]

This is a pes125i. Do you think only need to calibrate the injection or something like that? 
I took to the garage the guy told me some "electrical issue" he needs to take it apart , remove all the panels and and check everything. 

What do you think about this?

[robster]

I havent notice any extra smoke actually. Could be still the injection?
