Primary Chain Tensioner
New to Forums, so first I will say hello to all!
Have a question about checking the Primary Chain Tension. Is there anyway to check it without removing the primary cover? I am having a bit of a clank that sounds like it's coming from the back of the primary. Mainly when switching gears just chugging along or not moving and just blipping the throttle a bit.
Also curious if the M8 has an auto tensioner? If so is there a way to force it to adjust?
I've read many threads on here, no my floorboard isn't loose
. Maybe it's done it from day one, but it never hurts to ask. I have about 3K now on my M8. I know I can take it to the dealer but won't have time for a few weeks. Any help would be much appreciated!

The M8 has a auto adjusting tensioner.Sounds as if your problem is self induced by lugging engine and accelerating from a too low of RPM.

With the aid of a flashlight, You can see the chain through the derby cover opening, and you can reach center point of the chain with a 12" long slim screwdriver. push up on the chain and eyeball your slack.
Rapidly getting on and off the throttle hard in first gear will often encourage a lazy tensioner to do its job.

I had the same noise, I think. I was sure there was a knock in the primary. Heres what I did. I started the motor, laid down on the ground by the primary and listened. Sure enough there was a knock and it kept perfect time with the motor. Turned out to be the left driver floor board wasnt tightened enough. That was it..... go out to your bike and move the dang thing up and down.... You'll hear it. If thats it....
LOL.... I didnt finish reading your post... sorry

I have hear of folks mentioning to go quickly through a couple gears fast to get it to adjust. Never really knew if that worked or not. Again, nothing in the service manual to suggest it.
Thanks for the response!
