noise front end
on: 31 May, 2020, 05:38:38 PM
Hi
anyone got any ideas.? Every time I hit a pot hole, I get a rattling noise like plastic hitting metal. I've checked every nut and bolt on the mudguard and front end - all tight. The mudguards not cracked, and all the cable braces are good. The noise became more obvious after I fitted a front tyre. I did notice a rubber strip of 1 inch in diameter and about 1/8 inch thick around the front spindle to cushion the shaft against it's seating in the fork but according to the parts list, it should be there. so I left it out - I don't think it's this causing the issue. 

It's driving me mad? The whole mudguard only has two bolts either side holding it on, which seems to make the mudguard a bit too flexible.

any help appreciated Vim

Get the front wheel jacked up off the ground. 

Pull up and move the wheel should easily rotate SMOOTHLY and no forward to rear, up and down etc to test steering head bearings.
Just about bet the head stock is a little loose.  Some went to tapered vs roller  bearings

cheers mate  : yeah done that mate solid as rock. it's not the head stock and it's not the wheel bearings.
I hope he would have spotted anything like that in the MOT weeks ago but like I said I checked them anyway.

because you think it's metal on plastic check the plastic cover in front of the tank  (behind the headstock) the bolt has been known to come loose???

Release spindle pinch bolts and pump the suspension then re-tighten - to settle the right fork leg in correct natural position?

Bump the front wheel against a wall or freewheel it off a shallow kerb, to try and simulate the 'shock' in a more controlled and quiet way and listen for sound?

Why on earth would you deliberately leave an oil seal out?

You might have a loose radiator guard (if fitted)

Check bottom location fixing on each side fairing.

And put that seal back in situ. might need a new one now.

What age & mileage is the bike?

If it's a dust seal he's talking about it shouldn't have come out they are a tight fit in the hub and are generally trashed when you try and get them out, a pic would help to confirm it is a dust seal
