Quick question: do you check the slack on your chain when the bike is on it’s side stand or centre stand?
Obviously the chain is tighter when upright, but my chain is so loose it touches the swingarm when on side stand but is within 35mm slack when upright. So just wondering, what do you go by?
Go by whatever’s in the manual, because the tension given there (or on the swingarm sticker) will be based on how it tells you to measure it in the manual!
Technically you should adjust it with the weight of a rider sat on the bike, that's the old fashioned way.

No. Why would you do this? Does the manual say how heavy a rider you should put on the bike, or is the correct chain tension somehow dependent on the rider’s weight rather than the geometry of the bike?
It's a CBR600RR. The manual doesnt explicitly say to check the tension on side stand.

It is always on the side-stand, because every bike has one of those. Sometimes (but rarely) manufacturers will issue centrestand figures but they're *in addition* to side-stand ones.
The object of the exercise is to ensure that the chain is about as tight as it can be while still being not too tight when the chain length is at its longest - when the rear hub is furthest from the front sprocket, which generally happens at the point in the suspension travel where the front sprocket, swingarm pivot and rear hub are all in a line. “Not too tight” is a good deal less-tight than just "not obviously under tension and depends on a few things.
The manufacturer of your bike will have figured out what this tightness is and then figured out what that would be like as slack when the bike’s on its side-stand and stuck that on the sticker on the chain guard or whatever. Often people with centrestands get the tension on the side-stand right once, then stick the bike on the centrestand and measure it there, so they can always just do it on the centrestand.
the F had a centre stand, not the RR. Technically you should adjust it with the weight of a rider sat on the bike, that's the old fashioned way.

Aww, my bike is special. It is the centre stand only in the manual.
Sorry my post wasn’t contradicting… I was elaborating that he was doing multiple points to ensure he was doing at tightest point. I was alluding to the latter point
