Just an update, I went through and found a problem.
The sub mount tower setup has moved slightly upwards( not sure whether he removed this or not), but it was high enough to interfere with the cap that covers the headstem bearings etc.
Anyhow I moved this down 1mm and then tightened the headstem locknut and all good.
This has got to help me with the slow steering thing.
Just got to ride it now and check.
Hopefully one drama out of the way.
Cheers Mark
