« on: April 25, 2025, 04:41:49 PM »
working on a Downtown 300i and I know of the open seat trick but the cable disconnected about 24" down from the ignition and I cant find where to reconnect it to the back section.
Anyone have photo or instructions?

Hello,

I'm new here.  I have a 2013 Honda PCX 150, and was trying to get an XMAX (I ride 2 up a lot), but none were available.    I  found a really nice downtown 300i online last week and decided to pick it up, it's a 2015 with only 600 miles.   Is there anything I need to upgrade on it to help it's reliability?  So far, I read to not fill up the tank too full, and how to do the TSP/ISC reset if needed.   

1st is to make sure the seat cable allows you to open it, adjust it well

2nd  carry a second 9-12A battery with you, quick connect cable (increase charge cable fuse to 15A in case you need to quick boost)

3rd carry 10mm wrench

Downtown 300 / Re: won't start [SOLVED] was battery then starter relay
« on: July 30, 2018, 01:27:08 PM »
facepalm myself, yes the RED main wire was not connected.

The replacement starter relay is bad.
On the bench it will work fine.
When installed on the 300 in testing mode it works fine UNTIL
the relay is placed back in position with some strain on the poles from the wires, then
the relay will continue to be closed (unstoppable). The engine kill switch works fine, I have to disconnect any terminal on the relay or the battery itself.

Time to order another relay.

Thank you for the help

Downtown 300 / Re: won't start DEAD [new] was battery then starter relay
« on: July 28, 2018, 02:26:56 PM »
not sorted out, 300 is dead.
obtained a compatible 12v relay,
installed it and attempted a startup.
The relay worked and cranked the engine.
Engine started.
Starter would not stop!
electrical smoke was detected.
Kill switched the engine.
starter would not stop.
disconnected  black from relay.
starter stopped.
removed relay and tested it ok with bench tools.
300 will not show any signs of life.
battery is good.
all fuses tested with tester.
no signs of burnt out wires.

any ideas?
this is not covered in the service manual

Downtown 300 / Re: won't start oil alert [new] even with fully charged battery and jumper pack
« on: July 16, 2018, 04:15:47 PM »
updates:
I had a mechanic look at the 300 and we found the starter relay was bad (tried a used one from another machine, it was bad as well). We could jump the relay and start the 300 with ease. The starter switch activated power into the relay.
The service manual did not mention anything about relay faults nor did it mention several screws needed to remove panels for access. Nothing was forced nor broken.
New relays are on order.

Your battery is WAY TOO small! Your battery box will take a much larger battery and should have one that boasts more than 120 cold cranking amps (cca). The designator for a DT300I is something like ES12-BS. A battery that has a 9 or 10 where the 12 is is for a 150 or smaller. That is part of your problem.

I have the same bike, same year! Dealer stuck a cheap. 120 cca size 12 battery in when he set up the bike. I have a post with pictures that covers this whole deal. Of crummy, undersized batteries, that is.

thanks,
I've seen somewhere the 2013 model used the smaller battery box, the 2014 used the larger battery

ytx9-bs CCA=120 8A  AGM
I had tried a utz10-bs in it
8.6A  CCA 190
6"w x 3.5"d x 3.75"h
YTZ10S
but that battery was too old

Hope it works for you.

The 5/5 mark I usually go about 130 km on. It represents five and a half litres.

The tank total capacity is 12.5 L. Are you saying at 4/5 bars it took nearly 12 litres to be full to the base of the neck?

yes

yes, here is more info
downtown 300i 2013
2,000km

side stand is up
lights come up, pump sounds,
kill switch set to run position

updates:
managed to get a better connect with booster pack and recharged batteries I was using.
My charger was reporting full charges when battery was not fully charged, I switched to a smart charger.
battery is only ctx9-bs type (9A)
I also tried UTX10-bs
Now the battery light is out and the oil light is on.

I will check the oil system next.

Downtown 300 / won't start [SOLVED] was battery then starter relay
« on: May 22, 2018, 06:13:00 PM »
Swapped out the battery and hooked up a charged booster power pack with more than double the default battery.
300 won't start, shows low battery alert.
Is my 300 gone mental?

Downtown 300 / fuel gauge poor accuracy 2013
« on: May 22, 2018, 06:09:21 PM »
I've filled my tank and drove over 100km before the gauge moved down one digital mark.
Went and filled the tank and it took nearly a full tank.
Is this common?
