Cam Chain rattle disappeared?
on: June 11, 2021, 02:49:52 PM
Not sure whether this info is any use to anyone, but I came across this anomaly by accident.

Back in April I mentioned a slight cam chain rattle on initial startup after leaving the bike for a week on the side stand.

Since then, I've put a couple of pieces of plywood under the side stand when parked up to make the bike more vertical giving me a bit more room in the garage, and so far I've had no more cam chain rattle.

So then, is the oil draining out of the top end of the engine when the side stand is used normally, but by making the bike more vertical the oil remains in place when switched off and remaining there until the bike is started up again?

Has anyone come across this before?

I keep both my R and XR on paddock stands in the garage, so both live vertical in the garage, I still get the Cam chain rattle on initial start-up.

Iíve found that if you give the starter button a couple of jabs, turning the motor without starting it helps lessen the rattle on initial startups. Helps get the oil up to the tensioner and reduces the embarrassing rattle.

I have my side stand on a block of wood and chock the swinging arm so the bike is always stored vertical.

I do this because space is tight, but it is better not to store the bike on its side stand

I just think for the reasons above, IMO the engine is best left not leaning to one side.

that is reasonable, and I actually miss-read your post to say 'better to store on ss...'. guess I need to get my eyes checked!

btw all my bikes live either on center stand or paddock stand(the R and Xr still rattle on start-up)

If the chain rattle is excessive, you can swap for a mechanical chain tensioner. SoCal MotoWerks offer units for most models. No personal experience to offer but considering making the switch. http://www.southerncaliforniamotowerks.com/store/c1/Featured_Products.html
