I'm wondering whether I'll ever ride mine when they are done, they are going to feel pretty lame after Fireblades, GSXRs, R1s and now the XJR1300.....

Don't worry Pete.

It's not about performance, it's about riding a 40 year old bike.

My Triumph triples go fast, stop fast, handle well, start on the button and howls at 8k revs.

It doesn't draw a crowd, attract knowing nods from 50-something guys on the street, and doesn't make a sound that makes the hairs on the back of your neck stand up

News from the garage, she disappointingly fired up on 3 again, using the old spit on the exhaust trick I found no 1 was absent. I checked for a spark, fine, then whipped the floatbowl off to check all was well (I'm amazed how easy that is with the spring clip, though carbs 2 and 3 must be harder). Next I checked the air screw, 2.5 turns out. All the others on one turn, confirmed as the default baseline setting when I checked online. (I used to have to dick around with no manual and no info, now a few seconds on my phone and I'm looking at the info I need). Anyway, I set no 1 to 1 turn out, and she started on 4 straight away. Hopefully that's it, job done.  :)

The breather is baffling. As far as I could tell I can't get the screws out that hold the breather cover on as there isn't the headroom. I was hoping to find a blocked pipe, but although rock hard you can blow straight through. Revving the bike on the stand, there doesn't seem to be any substantial pressure coming out, though we know there is enough for it to blow down the tacho cable.

I'm not sure what to make of this, surely if I had blow by issues there would be an oily gale. My mate with a classic bike shop says it could just be condensation, with heat rising through the cable, and suggest taking the clock off and drying it out over a radiator overnight. He also told me a horror story of a customer bringing in a bike with a leaky tacho drive, and a cable wound so it acted as an Archimedes screw, actually half filling a tacho with oil!!

MrDavo:
This is turning into a blog of me snagging the K1 after years of inactivity, I'm back from the garage and finished for the day.

Tacho - a close look at my new oil seal, and I decided to tap it some more with a 10mm socket - it moved a centimeter or so further up the bore! I'm hoping that was my problem, we'll see. No test riding in this monsoon - more wanting to keep the bike pristine than being soft, but I also noticed that the tacho has lost its 'jerkiness' that I noticed yesterday - with the oil seal further up the bore it is engaging the spade with the fork better and not slipping out, I think.

I also gave her an oil change, and changed the brake pads. I noticed when I bought her that the disc was oily on one side, cleaned it with brake cleaner, but after a ride it was greasy again. CB750 brakes aren't great without being oiled, so a new set of pads went in today.The outer pad was in a right state, it had become contaminated at some stage (not sure what with - brake fluid / fork oil, or maybe the bike had been sprayed with something as preservative) and when it got hot the oil was  rising out.
