Rear wheel tyre valve

Postby Smurf1664 » Fri Nov 08, 2019 2:58 pm

As I haven't ridden recently and the Lady of the house is back in the UK for a while, I thought I'll take the 1150RT out for a spin and blow the cobwebs off. As an aside, I decided to check the tyre pressures on all our vehicles, 2 cars, a wheel barrow and the Beemer.

Cars and wheelbarrow all good, front tyre of Beemer slightly down by 0.2 bar. Rear wheel slightly down by 0.5 bar but couldn't get the air line to connect correctly without a lot of air escaping. After the 3rd or 4th attempt I thought "Sod it!" and as I disconnected the airline I could still hear air escaping!

Turns out that the valve had a split in it where it passes through the rim - bugger!! - so instead of going for a jolly, I shall be spending the weekend removing the rear wheel and looking for a motorcycle tyre shop!

Maybe somebody up there is trying to tell me something, as I have just noticed a few drops of oil on the garage floor which weren't there before.

Hey - ho, isn't life fun!!

Bad luck!

Don't know about Murcia, but most of the car tyre shops around me in Baza can do motorcycle tyres. The valve is really cheap.

The oil leak though, where do you think it's from, does it smell like gear oil or is it engine oil??

Hi Lurchio,

There is a motorcycle tyre specialist in Caravaca De la Cruz which I used to fit tyres to my R100s when I had it, but it may have closed down, as did a previous place I used for servicing about 3 years ago.

The oil is engine oil and the last leak I had was from the area of the clutch. That was fixed under the garantee when I bought the bike, and have had no further oil leaks since - until Friday, that is. The shop that fixed it is the one that closed down 3 years ago!

Will have to wait a day or two, as there is a Rememberance service to attend tomorrow. Let's see what next week brings

Hope you can sort the tyre valve.

I suppose best to clean off around the leak and warm the bike up to check. We have a service in Baza tomorrow, looks like it's going to be a cold one!

Cold is relative. Lol. You want to try being back in the UK today. A day for the Land Rover and not the bike. First hard frost of the winter in the Midlands.

Sorry about the long delay in responding, here's a catch-up.

The valve was a fairly easy fix, Haynes manual on how to remove the back wheel, down to tyre depot and a quick "can you help me?" "Claro," was the reply and 5 minutes later and 5 euros poorer I'm on my way back home with a new valve and a newly inflated back tyre.

No problem refitting and out for a short spin. Not much of an oil leak now, either. Strange.....

A month or two passed and after the lockdown, the bike was due its ITV, or MOT. No problems - in fact not much mileage since the last one either - All good for 2 more years.

Not a lot of riding after the ITV as the temperatures started to climb quite rapidly, 39 centigrade in the shade is not funny and I won't ride without protective clothing!

Back home after the ITV and lo and behold, the leak is back, not excessive but six or eight drops an the floor as opposed to two or three first time. So, off with the Tupperware and air filter to find the leak is from somewhere above the starter motor! Also, only four thousand kilometers since the last oil and filter change, cannot see the oil in the sight glass and theres neither that much oil on the floor nor on the engine. Additionally, returning home recently, gave a slightly vigorous opening of the throttle and heard the clutch slipping, just a little, but slipping nevertheless! Weirder and weirder.

Watched a couple of Chris Harris videos on YouTube and one of his comments made me think when he said that the rear crankshaft seal should not leak as there are two seals!

I'm not psychic, but I feel that the next month or two are going to be interesting, especially as the weather is cooling and I still have to finish painting the outside of the house that was started during lockdown

Sorry if this seems to be rambling on a bit, but my iMac died this morning and now my iPad keyboard won't let me type figures any more, only words!!!! Aaaaarrgh!!

BTW, I have both the Haynes and the Clymer manuals.

Who said life was easy...........
