Front vibration through leg shields to headset

[simonwwfc]

Hoping for bit of help been out today and noticed a few times I've got a funny vibration that seems to come from mudguard , leg shield , headset now scoot only done 550 miles since rebuild . If I hold front brake in and push down and lift up there's a knock sound coming from inside headset it seems any ideas on this please

loose steering bearings possibly?

Try applying the front brake as you push the scooter forward with your feet and, at the same time, place the thumb of your left hand over the joint between the lower headset and the legshield.

Can you feel any movement as you rock the bike backwards and forwards with the front brake on?

I've tried doing as asked cannot feel any play to be honest just this knock sound when pushing down on headset and letting off again with front brake applied . I've rechecked dampers settings as recently fitted I'm totally miffed now wot to do next . Do I renew fork bearings top and bottom to be on safe side

was it there before you fitted the dampers?

Forks might needed tightening in headset. Took mine to Bedlams in Bedford on Friday and Richard tightened them up. Only took about 15 mins.

Might be worth taking the dampers off and seeing if it's the same to eliminate them.

Also worth checking the axle nuts ate tight and the fit of the peg in the brake backplate.

Il look at getting it poss over to bedlams to let Richard and Ian to have a look at

Ian is a best mate but don't discount Richard, he knows all about scooters and is there during the week. Mark who now runs the mower side of the business wrote manuals/ books on Lambretta's.....

I had the headset/fork clamp crack either side of the fork stem. That caused quite a bit of a knocking noise

my moneys on the brake back plate locating being a poor fit in the casting
