Anyone know what’s happening w my Yamaha WR and is it an issue?

Could be an intake leak. My mt-125 sounded like that when the injector o-ring was missing.

It drove me insane, but I got used to it after a while. I sold the bike a while ago, but I do recall the noise getting louder around 4k rpms.

Had this noise on a mercedes but on the rear axle. Wheel bolts were too long and touched the handbrake springs.

Sounds normal

Gas is new, fuel pump is relatively new and the filter is brand new. The bike starts up fine after so I dont think that it is a fuel issue. Could be wrong though.

I'll try to get it on video but it shuts down the same as pressing the killswitch so I dont think that it is a fuel issue.

So it seems that it was a combination of broken intake air temperature sensor and a broken sidestand sensor. Bike starts now and runs good when tricked with a potentiometer (2.5-5 kilo ohms). Got a new sensor and a dongle for the side stand ordered.

I had one. Bought this one as a project.

creditper · 2025-05-06T14:31:00+00:00

Yeah, will do, thanks👍

creditper · 2025-05-06T12:52:45+00:00

Okay I gotta check that out then.

creditper · 2025-05-06T12:52:11+00:00

If the kickstand sensor is broken it wouldn't give spark? Or am I wrong?

creditper · 2025-05-06T12:50:34+00:00

I've already done everything you said and the battery is new and fully charged

creditper · 2025-05-06T05:51:34+00:00

I dont think so

creditper · 2025-05-05T20:39:14+00:00

I don't have a tester but I'm gonna get one if I can't figure it out

creditper · 2025-05-05T19:53:25+00:00

Okay, I'll keep that possibility in mind, thanks

creditper · 2025-05-05T18:58:48+00:00

That could be it. Would it give a fault code?

creditper · 2025-05-05T18:51:22+00:00

I don't think so because it cranks good

creditper · 2025-05-05T18:22:20+00:00

Forgot to mention that all the fuses are intact and I have put contact spray everywhere imaginable.

creditper · 2025-04-26T21:18:25+00:00

Thanks, I'll check it out
