Bike started by itself, went forward and fell.

So just as I was really enjoying my cafe build of my 2014 mag wheel, something crappy has to happen. Welcome your thoughts.

Iím about to take the bike to the grocery shop. I turned the key on. Armed the kill switch. Then go to put on my helmet. If I remember correctly the bike dash lights up and does it thing then starts - without me pushing the start button, even though the kickstand was down and the bike was in first gear. It went forward and to the left, got caught on the wheel of the bike to the left of it. I instinctively tried to pull the bike away from the other bike. My bike then went forward to the left and then dropped on its right side in front of the bike on the left. So no more than 5-10 forward. Kick stand was back up and the seat popped off from under the tank due to the friction. I hit the kill switch. I think that might have turned off the engine (?) but it continuously had the ďstarter soundĒ going on. I had to turn the key to get the bike to turn off.

After lifting up the bike and checking for damage (only a minor scratch on the right exhaust) I parked the bike, sat on it and with the clutch and brake i turned the key and armed the kill switch. The bike did the same thing ó dash did itís thing then tried to continuously start (unsuccessfully).

Any thoughts on this? It was pretty freaky to see my bike take off, however short of a ride, by itself. I would recreate it just to make sure I remember it correctly, but you know, who wants to recreate something like this.

Appreciate any takers.

Hereís my noodling on this.

I recently installed a TTP Breath. The side stand switch and starter switch are located nearby, also under the left side cover. Perhaps they are disconnected or not fully connected.

Iíve also been having problems with the LEDs flashing after it rains. (They turn on but donít flash, and then flash again once it ďdries upĒ). I wonder whether itís due to water getting in under the side cover and messing with the flasher relay, and whether this water phenomenon could also affect the side stand switch and starter switch which are nearby.

Iím grasping at straws. Really want the bike to work flawlessly again.

Will relook at the bike in the morning with a fresh mind.

Hi there

Thatís rubbish mate, hope that the damage is slight!

It sounds like you have some electrical gremlins there. So for the starter to turn on ignition then the starter relay must be made, look for your short right there. Also if you fitted a breathe bell mouth you will have moved all of the effected electrics for access... did you cross wire the side stand and starter switch? Did you fit the plastic flap to reduce water ingress? Also did you damage anything when you moved it? A photo of the wiring would help. As for the indicators then I would strip, clean and electrolube, then test and seal. Donít panic it will be something silly mate.

When you wash the bike do you pressure wash or throw buckets over it? If so, donít bikes arenít designed for it...

Classic starter relay waterlogged. Take a look at it under the left cover, it often hangs upside down due to the rubber holder perishing and letting it drop.


A drop of water between contacts Nļ 30 and 87 on the inside view here will make the starter operate as soon as the ignition key is turned ON:




Remove cover with penknike, if there's any water inside let it dry for a while or simply replace it, it's a common item and most auto stores will have a replacement for a few $.


Location (the emergency start button is a mod, yours won't have one on yours):

This forum is amazing. I went from confused (was it my imagination?!) to sad to angry to hopeful! Itís been pouring rain since last night and will continue another 8 hours or so, so I havenít gotten to checking the bike. (I really need to park this baby indoors somewhere)
@Bonnie59 - Thank you, really appreciate your suggestions. I will check out the starter relay. I did move the wires around, however I didnít unplug the switches to fit the bellmouth. I (not so simply) rerouted them upwards and around at max stretch. (Oh, I may have unplugged them to have a look-see. Maybe they arenít back on tight?)

You caught me on the included water guard. I was lazy and didnít install it, especially after seeing how small it was. I felt it was too brittle to really stop water entry behind the cover. This weekend I aim to install something a little more protective. Potentially wrapping a plastic bag around the switches (?).

I usually wash my bike with a little water-filled spray bottle, and then ďwax itĒ with a wash n wax spray. Once a year I may take it to the self-wash but there itís focused on the hard to reach parts like engine crevices and under the bike.

On the LED shorts Ill start at being more protective of the flasher relay. Iíll wrap it up in something first and then see if LED flashing can withstand the rain.
@Forchetto - Thank you. Really appreciate the photo attachment. Hopefully you hit the nail on the hammer with the short in the starter relay. Once the rain stops Iíll look at drying the switch out as well as protecting that entire under the left side cover area with something plastic.

Now I just have to be patient until the rain stops.

Hey Caramelgq

Thatís great, it is going to be something simple mate, sounds
like itís fairly moist where you are?

I really think you have a short in your starter relay and am confident you will be ok. You could think about using some electrolube around your connectors to keep the damp out and you can use the same to disperse water from your starter relay (and possibly flasher can?).

Good luck mate and keep us posted..

FYI...I have not been running the splash shield for the Breath since a few yrs now and I have been riding in heavy rain for hours, for several days in a row. The shield is really just an attempt to keep too much water out of the Breathe intake...but it really won't do much if you look where the rear wheel throws water. Never had this issue with the starter relay. I do have the emerg-start mod done to it (though I made the hole I did not put a stick/button in to press when needed...I just placed a poking stick nearby and strapped it in place with electrical tape, covering the relay cover's hole as good measure. Those relays are not weather proofed for living on a bike. There are better sealed one available. But just wrapping the two halves with e-tape should help a lot. Maybe even run some silicone on the joint? Whatever, you should pop the cover off it and hit it thoroughly with BrakeParts cleaner or at least WD ("Water Displacement")-40.

Sure, the shield is designed by TTP to reduce spray into the bell mouth, but as it is co located with the starter relay thatís a good thing ..,

But before you took away the snorkel and had no splash guard, all that water from the wheel still got up in that area where the relay is. Bike should not have the failure yours did from the tire spray. If you relay was water logged then either it was even more poorly put together than most or you hit it with a power washer or similar.
