Downtown 300 / Re: Downtown GT 2024 air filter box intake design problem
« on: November 09, 2024, 11:22:19 PM »
This is definitely an oversight by Kymco. They have been putting the air intake at the front for years, why did they change it.

I've also noticed there isn't a fender or mud guard that covers the top of the actual rear wheel, which should sit very close to the tyre surface. See the photo attached for the 2nd gen Kymco Dowtown 350i, which has this design to stop water being splashed forward and a hidden air intake on the top left of the air box cover to prevent water ingestion.

I think this will be an ongoing problem unless you are willing to modify the airbox (cover only) yourself. Maybe block off the rear vents, drill some extra drain holes and cut an intake in the front. This may affect warranty but simply replace the cover with an original one when required.

  Glad to hear good things about the Michelin City Grip 2 tires. I only have about 2000 miles on the stock Kendras on my People S 150, but want the best rain tires I can get. I get real nervous riding in the rain, and I understand the City Grip 2 is the go-to tire for wet weather.

Pirelli Diablos or Pirelli Diablo Rossos. The best tyres I've had for rain for 10 years, I just ride very similar to dry weather.

Downtown 300 / Re: Error 37

Tested like this? Screenshot from the service manual. If it's truly faulty the bike won't run.

Might be easier just to replace the whole ignition coil.

Definitely too much, even for the time before inflation.

Looks like they changed the design from the more common sliders on the ramp plate to pins which would slide inside the cylindrical metal holes (and bushings) on the variator.

Also your photo shows a roller with a very worn flat spot, more than enough reason to replace the rollers soon. They can get stuck and cause all kinds of issues.

Technical | How To / Re: Does voltage matter on glass fuses?
« on: June 18, 2024, 02:06:20 AM »
The voltage is simply the maximum rating for the fuse. 32V is fine and you will still find 250V fuses in automotive applications such as DC-DC chargers and inverters etc.

It's ok to go a bit higher with current (amp) ratings. Fuses never blow at the exact amps they are rated for, it just varies the time to blow.

« on: June 18, 2024, 02:01:41 AM »
This is normal and indicates that the ABS is working.

If the light stays on when riding then there is a fault, most commonly the wheel speed sensor and rarely the ABS module.

Technical | How To / Re: DTX360 (320cc) Oil Change
« on: June 06, 2024, 01:32:06 PM »
This is the correct procedure and the photos are helpful.

The engine is identical to the Downtown 350i but the 350i specifies 1.3L oil capacity. Unknown why Kymco made the change but the engine is not too fussy as long as you do regular oil changes and check levels regularly as I believe dilution with fuel is still an issue.

The oil drain bolt is 17mm and oil filter cap is 24mm for reference.

I get my new genuine parts from https://www.bike-parts-kymco.uk/kymco-motorcycle. The deliver from the Netherlands which is 2-3 weeks.

You might also have luck locally on eBay or Gumtree or Facebook marketplace, there could be a wrecking Downtown somewhere, just ask the sellers. I've been lucky a few times for used parts and it saved me hundreds.

Have you tried a ceramic coating, like Turtlewax? I did this to my car and the water just beads right off.

1st is making sure the plastic visor is extremely clean, water will bead off even without any coatings because of the cleanliness. Tiny microscopic scratches from dirt or sunlight breakdown will hold water, so get a new visor if necessary.

2nd is to use a ceramic coat to repel water as suggested above. Ceramic will last longer than wax alone and you can apply many layers to increase the water-repelling effect.

Products such as Turtle Wax Hybrid Solutions Ceramic etc work well.

Downtown 300 / Re: DT 300 Battery warning light, bad rectifier?
« on: December 25, 2023, 03:00:23 PM »
Hola amigos!

Just wanted to post an update on my issue. Good news; it seems to be resolved!, I have been using the generic 20 amp rectifier and battery is charging without issues, so that's good!

Bad news; new problem appeared and I'm not sure what it is. When I was putting everything back together I plugged my underseat led light and it didn't worked, the cables were really hot and I unplugged it, I think the light was shorted.

Just after that, the met-in red light from the dashboard stopped working and the check engine light.. is not on, it's more like slightly illuminated.. it gets a bit more stronger when accelerating, it doesn't turn on completely, it is just a very dim yellow light only noticeable during nighttime, but I think something is not working ok there.. also I noticed that my blinkers seem to varies their speed with the engine idle, they get faster when I accelerate.

I think I might have introduced some kind of electrical problem, but hey, the battery is charging perfectly!!

Thanks for your help guys!!

I think the underseat light is shorted, maybe a pinched wire during installation.

Hard to say but the first step is to measure the voltage output of the regulator. Use a multimeter to measure the voltage at the battery at idle and acceleration, should not be more than 14.5V.

Voltages too high or low can cause weird issues.

30 psi sounds about right. 40 is too high. What brand are the tyres, this has a huge effect on what pressures to run and handling.

Nice Xmas pics.

Do you have a waterproof jacket? Preferably 20,000mm rating or higher as they do a marvellous job in the rain without the 'damp' feeling or wind-flapping of PVC.

Something like Dainese D-Dry works well.

In Australia there are no plans for banning ICE motorcycles. We just wait to follow the rest of the world in trends and standards - especially US and Europe.

EV vehicles in some states already have their odometer read so are taxed $/km. Can see the gov doing the same for bikes in the future. No more subsidies.

California promotes a lot of this green agenda crap, yet this past summer, they couldn't even supply enough electricity for households, thus they told people to charge their electric cars every other day. These are the problems with all EV vehicles:

1) There is very little infrastructure to support a total conversion to charging cars. The batteries take a long time to charge.
2) There are not enough rare earth metals to make batteries to replace every single car, truck, motorcycle, train, boat, etc...
3) The current electrical grid cannot supply enough energy to charge all of these vehicles, thus carbon based fuels are needed to account for the energy deficit. Wind and Solar are limited because the Sun does not always shine, nor does the wind always blow(Unless you are a politician in Washington DC(possible source of unlimited wind energy))...lol
4) You still need to make plastics(which require petroleum products) for exterior and interior parts. You need forges to form the metal frames, which use tremendous amounts of energy, etc...
5) The Battery metals are hazardous to mine(think poor children, men, and women being exposed to Lithium poisoning). They are also hazardous to get rid of once they are depleted. So all the green hippies think they are saving the earth buy saving gas use, yet the rare metal pollution from spent batteries have a far more deleterious effect.
6) This green agenda is politically motivated, thus they are forcing an energy solution which is not feasible at this time. People's energy costs are going up and causing a domino effect on cost of goods and thus reduced spending in the economy.

This being said, hybrid engines are a great way to incorporate using less gas and some EV to reduce emissions. The batteries are smaller, but energy is recaptured through driving and breaking.

I'm not in the BEV crowd yet due to sheer cost. Very difficult at the moment to buy affordable electric bikes with comparable range, weight and speed to ICE bikes. The Harley Davidson Livewire for example is 50,000 AUD and comparable to a $12K 650cc cruiser/naked. The BMW CE 04 scooter is 22,000 AUD and comparable to a $9K 350cc maxi scooter, but with only 120km range.

However, there are workarounds to the points above:

1) People have an obsession at the moment with range which means bigger batteries which takes longer to charge. We need a cultural change so people are incentivised to charge smaller amounts at time, like we are happy to charge our phones several times a day without thinking. No need to have 100% charge all the time if there is better charging infrastructure, just like not having a full tank all the time because there are filling stations everywhere.

Some EVs have a VTL (vehicle to load) function which can supply power your home during peak periods.

2) This is true to an extent, there isn't enough lithium or rare earth metals in the world so we need to develop alternative battery chemistries such as sodium-ion.

3) Fossil fuels and nuclear are very important to provide baseload power generation.

However in countries like Australia, 1 in 4 homes have their own solar power and this is becoming more common, allowing people to charge at home. Not uncommon for homes to have a system up to 10kW which can provide 100-200km range per day (assuming 15kWh per 100km) in addition to household demands. Plenty enough.

Variations in supply/demand can also be compensated with battery farms and other energy storage which is important for renewables.

4) This will happen regardless of whatever cars people choose to drive. If anything this means less consumption of petroleum and depletion of deposits.

5) They are moving away from cobalt, of which 3/4 of the world's supply came from Congo, aka child labor.  Mining will always have issues.

6) Of course it is. The US and Europe want to reduce their dependence on OPEC countries which can be volatile and run by authoritarian regimes. The key word is sustainability - making existing resources last longer.

Hybrids - this is a good solution. The new Prius uses just 4.7/100km which is very good and more makers are offering hybrid versions of their ICE vehicles. Hybrids are not as expensive as they used to be and are a viable alternative to pure BEVs. Plenty of Priuses with 1 million kilometres.

I think HEVs (hybrids) and PHEVs (plug-in hybrids) offer the best of both worlds and are the immediate solution. They also excel in the city where most people live and use the fraction of lithium of BEVs.
