Just tried to check my chain tension in the car park at work,

I always park in the same spot each day and had the bike on the centre stand in this spot before but today the back wheel was touching the ground still.

Have I just found a dip in the car park (did move the bike back a bit and tried again and got enough clearance to spin the wheel) or has something gone wrong with my suspension / stand or has my new-ish shock just bedded in and allowing a bit more sag than before?

why are you checking your chain tension with no weight on the bike,
first off,
second your new shock is new so probably doesnt have as much sag, therefore longer not shorter than the old one

I've read about this happening when people put 1200 shocks in without changing the dog bones, or just changing the dogs without shocks etc.

Is your new shock a zzr600 shock?

because I don't have anyone to sit on the bike for me and so I'm following the hand book's guidelines for adjusting chain tension on the centre stand,

The bike's been up on it's centre stand with the new shock a couple of times here and I've not noticed the wheel touching, however I was checking oil level not chain so didn't look at the rear wheel.

It is a ZZR shock and the distance between ground and wheel at home was the same as usual this morning, however my patio is not flat which gives me a very handy clearance



so go find some flatter ground and stop being paranoid?

the manual for the fz6 states to check the chain tension on the centre stand with no weight on it

Yeah perhaps there's a slight dip in the road, let's face it, the clearance isn't huge anyway.

Got enough clearance but not nearly as much as usual which is why I was worried something wasn't right.


moved it about a bit again a short while ago and found it had the usual amount of clearance so just a dip in the car park that I hadn't found previously.

Hi

Would expect any dip that made that much difference to be quite obvious.

As to adjusting the chain tension with the suspension under load, why? The chain slack would then vary depending on the load, while the amount required to allow the rear wheel to move would be pretty constant (ie, even the lightest rider is still going to compress the suspension enough to get the chain to be tight when they hit a bump).

All the best
