Shortest ride out ~~Ever ?

[O.C.]

I had things to do today, but as the weather was so mild I just had to ride out.

The TPMS usually takes less than a minute or so to wake up, so as once I got a few hundred yards from home the low tyre pressure (front) warning lit up     not again.

So I  turned around and returned home with the front tyre pressure down to 30psi.

Close inspection of the front tyre revealed. ..................................absolutely nothing    

So, what happened then ? WELL,  yesterday I replaced both tyre valve caps with some  of these, all I  can think is that overnight the front one allowed air to escape

After being recovered from the roadside with a rear puncture only a couple of weeks ago I decided that on this occasion discretion was the better part of valour.

How weird is that

Is there a rubber seal in the new caps?

[O.C.]

Yes there is, and in fact they look very well made     

The valve top doesn't appear to protrude above the threaded part of the valve

Have a gander with a mag glass .. maybe just a small protrusion being enough to depress the valve.. or swop front and rear ..and divvent forget the SPIT test 

[O.C.]

I tried the  spit test but didn't see any escaping air

I'll check it again int morning to see if there's any further loss of air, I havent put any dust cap back on yet.

Maybe it's trying to tell you to stop messing with it and just ride..

     difficult with a flat tyre though Debs

My tyre pressure seems to have stabilised now and a short rude out today confirms that all is okay.

So no more aftermarket dust caps

Nothing like a good rude out Rog 

[O.C.]

  just noticed that Mo..it'd be rude not to    :mfr_lol:

front tyre down at 11 psi before todays short ride out...grrrrrrrr.....blew it up and it held its pressure perfectly

Will check again tomorrow,  maybe I have a faulty valve , so I'll change it and see how it responds

I'm getting a bit  off with it now

Don't suppose it is a Michelin tyre.

[O.C.]

...could be Pete, ...could be

You could change it to an Avon speed master.

 Using Michelin PR4's on the GTR I had punctures, using the same tyres on the K1600 I had none......luck of the draw, I think not! 


BMW don't allow their bikes to be inconvenienced with punctures.
