Rattling from right side of m109r

Tolov0007 · 2022-10-07T12:04:23-0400

Was heading home from work when my m109r started to have a rattling sound from the right side of the engine. Didn’t have a change in the shifting of my clutch nor did I lose any engine compression. The rattling sound remains the same when I engaged and disengage my clutch. The sound remains the same when I rev up my throttle. M109r rode home as usual only for the rattling sound. Like I said it runs fine outside of the rattling sound coming from the right side of the engine only. Some of my friends say it is the tubalur nut that’s loose in the clutch; but I don’t have no problems shifting my gears. One of my buddies say it’s the exhaust valve that is loose, but it runs mechanically fine outside the rattling. Has anyone ever had this problem before and if so how did you fix it.

Hello to you too... and welcome to the forum..Cheers.. 🍻
As much as we would like to troubleshoot your problem
over the net, It would be a guessing game without hearing
it. I suggest to try to videorecord it with the sound on.
IMHO I would not ride it much before you know what it is.
It is not a big job to open the clutch side and physicaly
see, if possible, what it is before more damage happens...

Thank you for the welcome

Here’s the link to my YouTube video of my m109r problem I am having. Thanks to all that response to my problem.

Welcome to the board. I heard a slight metallic rattle at the beginning of the closeup of the engine. Perhaps you can feel around to see if something associated with the exhaust is loose. Good luck.

Welcome. That sounds terrible. Take a long screwdriver, put the handle to your ear, then touch the tip to areas where you think the sound is coming from. It will act like a stethoscope to pinpoint the sound. Or if you have a Harbor Freight close by, they sell a real one for cheap.
I hate to make guesses, but if it's in the area you think it is, the most likely problem is the valve train. Either a cam chain got really loose, a valve bucket kicked out, etc. I'm assuming the rattle increases in step with the rpm? If it doesn't, then it could be something in the exhaust.

Does it has oil in it ?

Tolov0007 · 2022-10-08T16:20:49-0400

No oil

It doesn’t increase the rattling everything works correctly except for the sound

No oil , you need a whole motor.

I’m sorry miss understood the question I thought you meant oil around the motor. Just had the oil change last week using amsoil

Joe RC51 · 2022-10-08T20:09:11-0400

But have you checked it since this started ?

Zoom · 2022-10-08T22:09:32-0400

So to make sure I understand, when you increase the rpm of the motor, the frequency of the rattle stays the exact same? That is really odd. If it were the timing chain or something similar, the speed of the rattle would increase with the motor rpm. That to me kind of rules out things that rotate with the engine. Even the exhaust flapper would change noise as the motor speed increased. Did you try pinpointing the noise with the screwdriver or stethoscope?

My money would have been on shim bucket but he's saying it doesn't vary with revs...

Got be stuffed...

Had another set of ears to listen to the bike. The rattling sound does vary with revs. Also it was listen with a mechanical scope the rattling is coming from the top of rear cylinder. Oil was drain and measured 33.5 ml.

My money is still on shim. I wouldn't ride it until you have "your head checked"....

That's about an ounce of oil , your motor is toast.

nemom109r · 2022-10-09T22:20:34-0400

In your video, I thought I heard you say "it came back from a service", if that's the case, whoever didn't put oil back in it might owe you a motor...

Zoom · 2022-10-09T23:41:28-0400

Are you sure on the 33.5 ml of oil? That doesn't sound like it had any oil put back in it. I would think there would be more than just the one noise coming from it since you were riding it.

nemom109r · 2022-10-09T23:44:20-0400

33.5ml is less than a shot of liquor... EEK...
