Hello,

I just got a trail recently and it has been an absolute blast. I'm right under 200 miles at the moment. Unfortunately I just got back from a nice ride with a friend and when I started the bike it made a new noise. I know it always made a deeper electronic pump noise - but this louder buzzing is new and concerning to me. If anyone could please weigh in with what they think might be wrong. I have another 400 miles before I am scheduled for my first dealership visit - can I continue to ride or should I get this looked at immediately?

It happens when I turn on the ignition or if I turn on the kill switch - before actually pressing the starter and turning the motor on.

Any guidance would be greatly appreciated.

Perfectly normal I think. Mine has always done this. I believe it is the Idle Air Control Valve (16430-K0G-901) being pulsed by the PGM-FI Unit (38770-K2E-A01). Some sort of start up test I presume.

It’s a 125 working it’s little a$$ off. There are all kinds of noises that I overthink. I would not worry about it.

Any throttle issues? It doesn't sound concerning to me, but if you had dirty fuel it could clog the filter on the fuel pump in the tank, causing it to have to work harder when it comes on with the ignition.

hello everyone I appreciate the feedback so far - I'm hoping more people will continue to weigh in. I am about to go cold start it and take it into work. I will update if the issues continues today. No other problems with the bike tho - no throttle issues etc.

the buzzing noise is still happening today. other than that it still starts right up and runs just fine. I think imma stop by the dealership by me tomorrow and see if someone could take a quick look to put my mind at ease.

Mine makes the same buzz. Pretty sure it's been doing that since new. The bike is at the dealer for a different issue... I'll update here if they comment on the buzz.

stealership told me to pretty much not worry about it. I sent them the video and they said they would pass it on to honda to see if they could get any information. The dude said when I come back for the 600 mile maintenance that if they had any info by then he would let me know.

There's a whirr from the pump, and a buzz from the fuel injection system. Both should finish in a few seconds. It could be worth asking in a grom forum, they probably know more about the fuel injection system.

I was wondering because I don’t let my fuel level get too low when submerged as it cools the pump. Thanks.

Yup, I have one with 3000 miles and one with 10 miles. Both have whirring fuel pump noise and your vibration noise up near front of motor when key is turned on. So I would say no prob, normal noises.
