How thick is the swingarm on a thou?
 
Not the kind of question I ask myself too often however, a bit of mine is a bit thinner so would be handy to know......

OK. K3 Naked SV thou. Braided hose upgrade carried out by previous owner. By the main swingarm pivot point there is a weld connecting the "arms" to the "cross brace bit". It looks like the braided hose rubs against this when out and about and has actually worn a groove into the alloy of the swing-arm where it meets the weld.

I've not had a proper look at it yet, so few questions of which some may become stupid when I actually get out there and poke around a bit.

1. Is it possible for braided hose metal to grind a slot in the swing-arm?
2. Is there normally a groove to the outside of the off-side weld?
3. I'm probably less than 1mm deep at the deepest point. How much meat is there left?
4. What would you recommend putting in there as a buffer that will not damage the hose (bad) or the swing arm (very bad)?
5. Anyone got a spare swing arm for a thou kicking about?

Anyone got any real-word experience of what these things look like in cross section?

Cheers,
Mark

Just fix the brakeline to stop it rubbing, it'll be fine.

How about a piece of nylon spiral-wrap around the hose where it crosses the swing arm? If that's too visible try a piece of black rubber hose, cut along one side and wrapped around the pipe.

Oh yes, uncovered braided hoses are like a file. They've cut through all sorts - oil coolers on aircools was a favourite.

Not on the naked 1000 outside my house.

Loads, don't be paranoid about it. Can you put a picture up, then we'd know a bit more about the exact position.

Anything will do it - but I'd restrain the hose and consider it's route - a subtle change may make all the difference.

A naked thou? Be serious - that's like asking for good S/H naked curvy clocks :D.

+1 Spiral band is good stuff.

Can usually find it at electrical wholesalers
