Slow puncture/anodising problem. 1100GS

[Robh1664]

Evening all,

when I picked up my 1100GS a few weeks ago, the then owner pointed out the slow deflation of the front tyre. No problem says I. It needed a new tyre so I took it to my local bike shop for a new one to be fitted. I was told on collection that there were patches where the anodising had peeled along the bead seal area of the inside of the rim, just like chrome does when it's had it.

They had smoothed it out and used a bead seal 'gloop' and hoped it would now seal OK.
Checked today (24hrs after fitment) and it's flat.

Anyone have any idea's.....

New rim, re-anodising, powder coat or sell it and buy a KTM (joking about the last comment)

Cheers, Rob.

sand paper.
Well it worked for me on Guzzi rims.

 

[Robh1664]

They reckon they did that. He is a very knowledgeable bloke but maybe not done flat enough. I think the anodising must be a really thick plating. He did say it may not work, hence my post on here

Stupid question, maybe, but is the valve good?

Clean the rim with very fine sand paper, wash the rim to get rid of all residues and apply some liquid rubber to the point of contact and remount the tyre, it should solve the problem
You could as well change the valve and apply rubber sealant again before refit

 

[Robh1664]

Yeah, I'm going to take it back to the shop in the morning. He did fit a new angled valve. I intend having powder coated rims, stainless spokes and a much lighter wallet, but not until next year. So hopefully I can get it sorted untill then.

Just in case.............
does the 1150GS front wheel fit the 1100GS (that I own). There are a few on eblag.

If it's gone down that fast, pump it up and check it out in a big bowl of water, or look for the leak with w/up liquid - it will be easy to find.

 

[Robh1664]

I'll do that. Got to see if the bike shop will sort it out first.

Double check the valve and give it a wiggle.
I had one that was dodgy - in fact it bloo out !!

Some rim tape and an inner tube until you can sort a permanent fix, just to get you mobile...

Fair point, but that doesn't help you identify the root problem

I put that just to get him mobile again...
Enough help from others on the thread, the chap might need a quick fix until funds / time allows for a permanent cure.

Fair point again. But actually identifying the root source of the problem (which is easy to do, costs little in time, and nothing in money) facilitates the permanent cure and is likely to save funds, even if you need a quick fix to tide you over. No offence.

A weak spot is whare the valve seats in the rim. Take out valve and clean hole put in new valve unit. JJH

Inflate tyre and spray a solution of washing up liquid and water over areas where you suspect it might be leaking from such as the valve and the bead. You will soon see where the leak is.

Smug - Thanks for underlining common sense. See my post #8.

ROBH 1664 - Identify the source of the leak first and potentially save yourself all sorts of potentially spurious and unnecessary labour and other costs applied by "the bike shop", to stop you being ripped off. If you need a quick and temporary fix, e.g. a tube, at least know what the base problem is first, otherwise it will be harder to identify.

 

[Robh1664]

Thanks for all the advice. It does help.

I've known the workshop owner for years so no problem with him. £12.00 for tyre fitted and ballenced (loose wheel), I reckon that's cheap ! I'll find the leak and mark the rim, drop it back to him and I'm sure he will have another look at it. My big concern is that the peeling (carrosion) of sections of anodizing may have created hollows that are too deep to smooth out, hence the leaking. If it can't be sorted I'll stick a tube in it untill funds allow a new rim, re anodizing or maybe powder coating.

It would seem that no one has seen this peeling of anaodizing on wheel rims..........does this make me special

I thought all 1100s had plain alloy rims- my '97 certainly does.

I thought they were plain Ali too.
