Do you mean the headset came loose after 5 mins of riding? If so, its likely that the cups were just settling in. Readjusting your headset should sort it out. That gyro needs fiddling with though, you've not got it adjusted for the best performance at the moment.

Take a photo of it straight on from the front and I'll talk you through it

Ok. The pics are a bit small, but basically do this;

Start at the handlebars.

1. if the cable is adjusted at the lever, then loosen it completely (wind it into the lever)
2. your upper cable has an adjuster in the 2 into 1 bit. Wind this all the way in.

You should now have a very loose crappy lever.

Go to the back of the bike.

3. If you have adjusted the lower cable down by the brake itself, then wind that in all the way too. (ie loosen it)

Basically, you're un-adjusting everything there is.

Your brake lever should feel like shit now.

Now go to the gyro itself.

4. Start with the lower cable and wind both adjusters down equally, so that they are as far down as they will go without falling out. Do the locknuts up. If you can't get the adjusters down because the brake goes tight, you need to loosen the pinch bolt and let a wee bit of cable through at the back.

5. Go to the upper cable and wind both adjusters UP equally, as far up as they will go without coming out. Do the locknut up.

You brake lever should have some feel back in it now.

If the lever has any free play, take this out with the lever adjuster, but do not use this to tighten the brake overall.

If you need to tighten the brake overall, then go to the back of the bike and make your adjustment down there.

Now when you look at the gyro, it should have the biggest gap possible between the upper cable plate and the gyro bearing. This ensures that you cant pull the lever hard and 'top out' the gyro, if you know what I mean.

Once the cables have stretched in, make any further adjustments at the back of the bike closest to the brake. Only use the lever adjuster if the lever itself developes any free play.

It sounds long and complicated, but follow the steps and it'll make perfect sense. Do it any other way and you could be pulling that lever with all your might, and you'll just be stretching cables......

You could put a drop or two of 3 in 1 oil down those cables while you're there, they always need it- even from brand new.

Have a go and stick me another picture up once you're done

tell me something... the cable position in the handlebar.. and were they "pass" are correct?
I will print your step by step and go and do it correctly this time.

thank you.

Cheers

Reads a bit like War and Peace, but it's a tricky thing to explain....

Flavio, the cables are fine but I would say the upper cable is just a bit too short really. You might struggle to find a longer one though these days. I wouldn't worry too much about it.
