Issues with brand new Downtown running rough and cutting out / stalling

[zombie]

Easiest way to check for water in the fuel (all Ethanol fuel contains water) is to open the bowl bleeder screw on the base of the carb, and let it flow into a clear glass jar. Let it sit for an hour, and you will see if there is SEPARATED water. If it is a FI bike then pull the fuel line off the throttle body, and let the fuel flow into a jar.

Ethanol attracts water, and can only hold so much in suspension. After that point it is water.

Good reason not to use ethanol. I will drive out of the way to get the good stuff. I have 2 stations near me that sells non ethanol gas and I have an app to help me if I'm on the road to find it.

Any updates, msolok?

I am up to around 1,600Km on the Downtown now. Since dropping is off at the Service Centre the first time there has only been 1 incident with it stalling. Other than that it's been running well, nice and smooth.

It took a long time for the switch block to come in to fix my headlights issue. But it's now been replaced and it is running well. I am quite happy with it, even after the initial stumbles.

glad things worked out in the end.
my scoot (dt300i) has stalled on me twice so far. in traffic. both times when suddenly releasing throttle before/at a stop, but could start it quickly, still not a pleasant experience. suspecting gas but not sure... have the iridium plug at home but haven't changed to it yet. maybe that would help?
another question: what is the correct idle rpm?

[CROSSBOLT]

Msolok, that is great the thing is running normally! Nushipwright, idle should be 1650 +/- 50 rpm. You do the INITIALIZATION yet?

Karl

CORRECTION! IDLE SPEED SHOULD BE 1600+/- 100 RPM. Well, I was close.....

This is how its done:

I would still take your scooter back to the dealers & have their mechanic look at it just to be safe. It should not cost you anything as it's new & you don't expect any problems from a new scooter. When I first got my scooter I accidently left the key on & drained the battery. Fortunately the nice people who sold me the scooter replaced it with a new battery free if charge. No problems after that dilemma. I believe the Downtown to be a very reliable scooter. Good luck

An issue just came up with one of our dt300 on the showroom. Went to test drive it and no spark. Found out that there is a hazard control unit under the seat on the right side. A brown box that looks like a cdi with 11 wires coming in and out. In plug it and see if it fixes your issue. For some odd reason it has partial control of the ignition.

What is a "hazard control unit", B&L? I do not recall a brown box on machine right on mine. How big is this brown box? I need to go look again......

I didn't know about it tell yesterday when our DT started messing up. It controls the hazards and apparently something in the ignition system too. If you take your seat bucket out it's about half the size of a cigarette box right behind the rh side seat latch. Two green connectors going to it. You cash in plug it and test if that fixed your stalling issue.
