FT: Frame (Twin) RFM Suspension Lugs

[Herman-Handlebars]

Hi, I'm starting to restore my RFM and am questioning the condition/thickness of the material around one of the lugs (rear lug in the pic)
I'm very much new to Vincents, so am just asking if this is acceptable and normal when the bronze bush is fitted? Or is this too thin and may lead to fracturing over time.
Any advice would be greatly appreciated, before stripping, painting and fitting bearings

See bush Ft117 on parts drawing MO22.

It's been working for probably close on your life time (and it ant broke yet) the action of the lug is in compression mainly so renew the bush and carry on my handsome. If it bothers you buy a new RFM the peace of mind will cost only £3,000 , that is little to what it's made you over all the years you have probably had it.

Just press in two new bushes and ream them to size. The reamer should preferably be long enough to pass through both bushes (piloted) so that they are perfectly in line. I just used the short reamer I had to hand when I replaced mine and that worked out OK.

Thanks all, sorry could of written my question a bit better.
I wasn't sure if I am just over thinking the 'what if's' in if the lug is strong enough. I suppose I'm asking if this is normal to other RFM's. There is about 3mm of material compared to over 5mm on the other lug. The frame has been stored for many years and I don't really know of its history unfortunately.
The holes though seem to be round and with a little bit of fettling, seem to be ok to press in the bush's.
Does anyone line the internal tubes with anything like an anti corrosion paint or sealer?
Cheers

Best do yes.

And use it up, to just before it breaks.

Who knows, its old stuff...
