I had them serviced due to excess oil on one of the stanchions.
The stanchions look fine, everything else seemed fine too.
On the first ride i did about 6 miles before i got to a point where i got some speed up.
On full extension; say if i pop off something quickly. It makes a noise like a dodgy 1970's mattress!
Its fine and dandy until you get airborne, then its noisy. Never done this before.
I've called the tuner and he said it may just be bedding in noise. As he has changed the settings to recommended setting. But i'd done 11 miles in total. I've just done another 11 and its no better.
I'm going to take them off and get them back tomorrow if i can.
Whats the likely cause of the noise? Its more so i don't get fobbed off really. Hopefully its a simple assembly error and no damage has been done.
I've had similar with Vanillas in the past. IIRC the coil springs have a plastic sheath covering them which can shift position causing them to rub on compression - just double check it's in the middle of the spring and hasn't wandered upwards or downwards.
Seems fine until it extends fully and quickly.
Can it distort and catch?
Its a definite metallic squeal/groan.
Yep, that's the noise I had. Just remove the left hand (from rider's perspective) top cap and check - spring should have the little plastic cover in the middle like this . . .

Thats where its sounds like it is!
I'll nip in tomorrow and get him to check though!
At least its not too serious!
