Fork oil
Where does the noise in the forks come from? I went to NLM and some of their Kanguro forks make a noise but not as bad as mine. NLM sugegsted that I might have too much oil in there. They also hinted that they often use higher viscosity oil to reduce play in the parts although 5W is best if the bike is to be used on rough tracks.
The recommended quantity is 230ml, I had put around 280ml in. When I removed some the noise did reduce but is still there. I messed with various weights of oil and levels and determined that there is some vertical play in the fork damper.
I could detect this when i stripped the fork. These forks are very easy to pull apart as there are no external bushes. Just undo the bolt at the bottom and they pull apart.

Land's End Trial
No work on the Kanguro for a few weeks. I've got some final preparation to do for the Trial and then I'm taking a holiday whilst down in Cornwall.
Wish me luck.

Noisey front end
Over the last few days I've cleaned the front end bits, decided that the steering races are fine and worked fresh grease into the bearings.
The lower triple clamp and stem were replaced by tying the front of the frame to the work stand, tightening the adjuster bolt and then hitting from the bottom. As for removal a cycle of hit-tighten got it there.
The big problem is that although I'm certian I've adjusted the head bearings correctly there is still a noise!

Mudguard support
The front mudguard is held onto the triple clamp by three bolts and a broken one. The bolts came out readily and with a little luck I managed to drill down the broken bolt at 3.5mm without detouring into the alloy. I then progressively enlarged in 0.5mm steps to oversize and fitted a 6mm helicoil.
Most of the PO's red paint flaked off the plastic with a little effort with a stainless pan scrib. Look better.
