Had to do a few things in prep for some winter riding.
I noticed the clutch cable looked like it had started to fray, so ordered a Triumph replacement, and when I took it apart, it'd actually frayed significantly. I think it was the original cable from new (the bike is 2001), so it's had a bloody long life.
Got a local mobile chap to put 2 new tyres on, and picked Michelin Road 5s as I'd heard good things, plus I know I'm going to be doing the winter miles this year, so decided to splurge. I've never put new tyres on this bike up to now, and as it turns out, the new tyres were rubbing against my rear hugger.
Took the rear hugger off, and after some counting, it turns out that the chain is 2 links shorter than it should be, resulting in the wheel being much farther forward on the adjusters than it should be. The hugger's off in the meantime, until I need a new chain & sprockets, when I'll order the correct length chain, and will re-add the hugger. The inside of the hugger is full of scrape marks that look like the previous owner was happy to just let his rear tyre rub a hole in the hugger until it was no longer a problem.
Had a look at the coolant reservoir, and realised there was a ring of rust around it, so flushed the coolant with 10L of distilled water and re-added fresh coolant. The resulting bike temperature is exactly the same, but another little job out of the way.
Can now feel a slight clunk when pulling away, and another thing we noticed when the rear wheel came off was that the drive cush rubbers are knackered, so that'll be the next thing to sort, and it's overdue a valve clearance check...
