Anybody got any ideas? I've done a load of work on the bike over the weekend:- New front tire. Forks out for a repaint. ABS sensor and ring removed from front wheel cos I removed the I-ABS from the bike 5000 miles back. Battery off so I could re-paint the bat carrier. Put it all back together. Every thing works just fine but about 1 second after i turn on the ignition the brake light comes on and stays on

Most likely - the switch for the rear-brake is stuck?

a spray with WD40 and a work back and fore, should do it.

I'll give that a try this afternoon Al. I thort maybe the 1second delay was a sort of fault warning

but everything else works good. I was pulling the breather pipes (that run behind the foot brake) about trying to re-arrange them so perhaps I've disturbed something down there.

Mmmm - could be an ABS fault, I've not got ABS. check the manual?

don't think so. as i say in my post i chucked the I-ABS 5Kmiles ago and its run good ever since

Turn on the ignition with the front brake already applied.

If the brake light comes on immediately - then it prob ain't the back brake switch that is faulty - it could be a remnant of your ABS-ectomy

Quite likely, it's only a little microswitch & the breather pipes can foul it.

That would be my guess as well but i can't work out the delay

I hope you're right Mr 'feral'. As I say, because I had the front wheel out I took the opportunity to remove the (redundant?) ABS sensor and also the 'ring' from the wheel. On re-assembly I followed the proceedure
of IGN-ON, Open=Close throttle 4 times IGN-OFF without engine start. Working on the theory that it's absense had registered a fault with what's left of the ABS 'brain' I again removed the tank and re-fitted the ABS sensor but to no avail. And yes Dai, That's the bit that's worrying me.

I was fettling till late last night and loseing concentration. I'll tackle it afresh after lunch

Here's a pic of what's left of my I-ABS that's still fitted to the bike. One of my tasks was to make a weather-proof cover for it out of an old VHS-Vid case.

Hmmm ... I thought you'd removed the lot

On the ABS bikes the brake switches feed into the ABS unit which then provides the signal to the lamp. Bloody ABS

I left the plug on in case I needed to'backtrack'. As I say it's given no probs since I removed the I-ABS 5000 miles back. I'm off to my garage, the other side of town now to check the rear brake micro switch. I hope you're right and that's the problem.

Watch this space

Whew, problem solved

These two pronges, 3rd+4th from the left. One was pushed back the other was bent

Sorted and back together now

Thank goodness that's over. Got stuff to do tomorrow and my bikes my sole means of transport,

Apart from me bus pass that is.

As a matter of interest, here's my air filter that was fitted new in March.

It's realy crying out for a Val Singleton there Nick all the crap will then just fall to the bottom of the filter and not block anything, once a year take it off tip upside down to empty sprey from outside with brake cleaner then when dry spray with 3 in 1 with ptfe put it back forget about it for another year
I got my K&N from OPIE oil's [can't remember the part number but it's on here many times and should be easy to find]
