New to the Rocket Family (Stalling Problems)

[SockIt2Me]

I just purchased a 2016 Rocket III Roadster.

I first want to say, I love the bike.

Have some issues. The bike is Stalling when I downshift to come to a stop. It is always when I'm coming to a stop. Sometimes a normal stop like a green turning to yellow. And sometimes more random like when a car in-front of me is turning and I have to come to a stop. But the engine is stalling and oil light comes on. Almost 10+ times in the 300 miles i've put on it, bike only has 310 miles.

I have read many forums and pages even on this site, but cannot come to any good conclusions at this time. I can take it to the dealer but I don't want to have this plague me. Has anyone actually had the issue be resolved and lived to tell about it?

Thanks

My 5 week old 2016 Roadster stalled TWICE, exactly the same way as yours did. Both times I was downshifting to come to a stop and the engine just died. The electrical system was still active, the engine just quit. The weird thing is that both times this happened it was at the same intersection at the same approximate time of day! The bike started right back up without any more problems.

Last week I took it in for the 500 mile service and mentioned this to the dealer so he could check for problems. Nothing was found, no failure codes were noted. It hasn't happened since so I'm keeping my fingers crossed.

The 50/50 87/93 octane gas mixing is also interesting. My dealer told me to run at least 89 octane in the Rocket so that is what I have been doing. Yesterday I decided to try the 50/50 87/93 mix to see if the bike would run any better....now I find out that the group says to run plain 87 octane. Why is running higher octane gas bad for the Rocket?

I'm running 99 octane and find it way better than the lower ones.
I also have stalling issues when de-accelerating to intersections.
Tried to adjust the tps and stepper motor myself using Tuneecu, it helped quite a bit, but can still happen once in a while.

Everyone thanks for your kind words and advice.

Ultimately I took it to the shop and they put a new more rich factory tune, it no longer stalls.

It did begin popping out of second into neutral under normal throttle at around 5k miles. It's still in the shop getting rebuilt under warranty. 2nd gear and all parts associated and a new clutch.

hello diaspoz,

i had/have the exact same issue with my 2017

it was really bad so i took it to the dealer (a 125mi ride) they hooked it up to some electro-gadget-gizmo-thing-a-majig and gave her back to ride home.

took her out the next morning and within the first 5min she did it again, twice, argh! BUT i rode her around until the tank read 8mi of gas left, then filled her up with 87. until this i had been running 93.

now with the 87 she hasn't done it anymore, so i think it's a combo of both the dealer's re-tune and the 87

notice the re-tune was done with 93, THEN i swithed to the 87. somebody here who way smarter than me on this stuff (and that wouldn't take much, i just ride 'em) can explain how/what effect this 93re-tune and 87 running effects the bike's performance. it seems to work for me as it hasn't happened since
