The centre stand is really handy for maintenance and you won't feel any difference by removing the weight of it. You'd be get more benefit by ensuring your tyres are at the correct pressure, your brakes are clean and aren't dragging, your air filter is clean and your chain is lubed and at the right tension. Basic stuff like that. Minor weight savings won't make any difference
I agree it's too lumpy and i couldn't stand the whiny gearbox noise to the bike so i changed it straight away anyway
Do they drown out that foccin great clunk going from first into second also?. If so I'm in .
My Fazer FZS600 hardly makes any noise, or clunk going from 1st to 2nd, but, I do get a clunk when going into first from neutral, especially when going into fist with a cold lump, I find slightly easing the bike forward with my tootsies helps to alleviate this.Chain tension is important, this is one of the reasons you need a centre stand, spin the rear wheel by hand checking the chain tension on the lower chain run directly under the black swinging arm chain guide that is on the top at the front of swinging arm, and make sure you have 1.5 inchs of movement pushing the chain up without excessive force. I understand this is the accepted measurement for a 2003 FZS600 Foxeye. See photo of manual.Although I have read somewhere that the chain adjustment should be made with the motorcycle on the side stand, so that some/most of the bikes weight is on the suspension.I have always done mine on the centre as its easier to adjust it with the rear wheel off the ground.

That clunk when you knock it down from neutral into first can also be caused by worn cush drive rubbers in the rear wheel. As the rubber wears it creates a bit of free play between the rear sprocket carrier and the wheel and you feel it as a clunk. You rocking the bike forward might be taking up the gap. You can check if there's any play by grabbing the rear sprocket and rotating it clockwise and anti clockwise.
If there's a slight amount of play in the chain when the swinging arm is parallel to t4he ground, then there'll be plenty of free movement in any other position as it's only going to get slacker whether weight is added or removed.
Think about it why does the chain need slack in the first place? It’s because you have to allow for changes in chain tension due to the up and down movement of the swing arm due to the suspension compressing and extending. The position of the front sprocket is fixed rigid to the engine and the engine is bolted into the frame so the position of the front sprocket can’t move up or down but the rear sprocket is part of the swing arm assembly so the position of the rear sprocket changes, it has to move up and down relative to the front sprocket when the swing arm moves up and down. If you look at picture 1 Imagine that picture 1 is when both wheels are on the ground the distance on side A is equal to the distance on B. In picture 2 say you hit a bump as you're riding and the suspension compresses and the swing arm pivots up around it’s pivot point so the rear sprocket pivots up relative to the front sprocket. This means the distance on side A will get shorter and side B will get longer so the tension on side A will be less and the tension on side B will be greater. That's why you need slack in the chain. In picture 3 when you put the bike on the centre stand you’re doing the opposite, you’re taking the weight off the rear suspension so the suspension extends and the swing arm pivots down so side A would get longer and side B would get shorter creating more tension on side A and more slack on side B. That means if you adjust the chain to have 30mm slack on side B when the bike is on the centre stand, when you put it back down onto it’s wheels and the suspension compresses and the swing arm pivots up side B will tighten up and you’ll have less than 30mm slack. YamFazFan proved that’s what happens with his measurements. On the centre stand he measured 30mm slack. When he put the bike on both wheels he measured 26mm because the weight of the bike caused the suspension to compress and the swing arm to pivot up slightly. The slack side will tighten even more when you sit on the bike because you’re compressing the suspension more and that’s causing the swing arm to pivot up more. It'll tighten more if you have a pillion. And it'll tighten more when you hit a bump in the road.

I don't even measure any more, i started using the "Unfazed" way by pushing the chain up until it just hits the chain slide. It seems to be adequate enough.And don't forget the manual suggests 30-45mm play on my bike so it's not that critical. It's the sound effects that play more an important role for me.
