Check:-
Wheel bearing play.
Tyre seating correctly on rim.
Spokes all tight & wheel running true.

Hi Brian

Spokes all seem ok tyre seated ok slight deflection on rim but only a tiny bit

Too much preload on the rear spring

Hi Mike

I only noticed at the weekend going down to Fairford fully loaded

If you can rule out a mechanical or tyre issue, then the only other reason is there is too much weight on the front end ie the forks are dropped through the yokes for some reason or there is too much pre load on the rear which is lifting it and causing it to be nose heavy. Same effect anyway.

Is it the original spring or did the owner before you put a much heavier spring in? etc

Should be able to true the deflection out with spoke adjustment.
Very important on heavy bikes that wheels run true.
Also check telelever wishbone for joint play.

are you after putting on a new tyre by any chance.

sometimes a bad or worped tire can get through factory inspection

got one myself a few years ago,

Hi Mike

The spring is the original as I got the bike new there is a small deflection on the front wheel but nothing to right home about I will check the yoke thing tomorrow if I remember the rear shock is on almost full so hard setting

Thanks Steve
