Yes, and “saga” is one of two Icelandic words commonly used in English - do you know what the other one is?
Geyser. It's all them like volcanoes and all that what they've got..
I rode it, it rattled - more of a clicking really, it sounded to me like a small end or gudgeon pin, so I took the top end off. A bit of necessary investigative surgery if you like.
Happily, as on the rest of the bike, all nuts came undone easily, thanks to dry USA air.
This is a lovely view down the exhaust port, all looks ok so far except the remains of rust corrosion on the bore (right hand side of pic if you can see it).
Copper head gasket was re-used after annealing.
Unusually, these and DT models don't use through studs, but separate studs for the head and barrel.
Head looks unmarked, suggesting it hasn't been run without air filter, which is good.
Tapped the barrel (it's located with dowels) and slid it off to reveal a piston that has more scars than a Prussian aristocrat. It looks tired and damaged (like all of us) but not like it's had a bad seizure.
Same on this side. Yuk!
The gudgeon pin was tight, so I improvised a puller/pusher with a 2 legged puller, a bit of metal, a big nut and a rag- it worked fine, and the suspect small end turned out to be ok, but for a couple of quid it seemed prudent to assemble it with a new little end bearing from Wemoto.
This is the matching damage in the bore- as there is rust, I think it might be from turning it over/running it after being stood idle for years, and the fine corrosion shown here has smeared into the piston.
Not having time (or the dough) for a rebore and piston, I rubbed the bore down with very fine abrasive paper and took out the rust and marks- I did it at roughly 45 degree crosshatch pattern as in the original honing pattern.
Cleaned bore thoroughly! Don't want to leave any abrasive in there...
All re-assembled, started fine, ran fine- but still clicked!
I now think it must be the piston/bore making the noise, something to sort out later if feel it's necessary.
So it's nearly there, just a few minor details like the MOT! Watch this space for how the IT gets on with that.
