Chain tension

[ThunderGuts]

Hi,

I've had bit of a look through other posts first but can't seem to get a conclusive answer; on my MY2019 CR I understand from the owner's manual that the chain tension should be 30-40mm. It also implies that for European models this should be measured on the side stand. There is, however, no mention of having any load on the seat to compress the suspension, yet I've come across this remark on here? The other thing is how to measure the tension . . . normally I just take the centre point between the sprocket and wheel axle, then measure vertical movement on the bottom chain run. Except on the CR, doing this means hitting the swingarm's lower edge before the chain has gone taught, so it'd go a bit beyond the swingarm in theory if it wasn't obstructed. Not so easy to measure the tension then without just guessing!

Has anyone got any ideas or alternatives?

Cheers

I don't focus on too much on the detail.

Side stand, ensure there's some slack, clean and lubricate. I don't measure it, I'm sure that's just a guide (hence the margin), as long as it's somewhere close.

YMMV

Cheers. I'd say it fits in that category at the moment. I'm a little paranoid about chain tension as I had a near-miss on my singlespeed push bike where the chain was too slack (only slightly!) and it climbed off the sprocket and got tangled.

I think you'd have to have it incredibly slack for that to happen on a motorcycle chain.

I futzed with mine recently on center stand then had it too tight when on Side stand. Lol.

I'd do like Skids does and not worry too much. It's hard to measure accurately as the shape of the swing arm impedes measurement. I did a best guess when on side stand and just slackened it off slightly.

Thanks guys. My handbook (RC60 model), recommends 1"-1.6" chain slack.
On the main stand, it's got much more chain movement than that.
Was wondering how/which position the bike needs to be, to measure chain slack.
When I bought the bike, it was 1"-1.5" slack on the main stand.

Make sure that there is still some slack under load!

My Owners Manual says it should be measured with the bike on the side stand.

Thanks SKIDS.
Found an online service manual that said the same methodology.
