What have you done to your Triumph today?

^^^^ Agree. There are also of course quite a number of name brand oil flush additive products out there, but I might be a bit worried about their effect on wet clutch discs?
The engine oil doesn't go in the primary chain casing, does it?
 
Starting in 1969 they left the primary side crank seal out and let the crankcase fumes(and stray oil splash) breathe into the primary case, with an elbow on the back side of the primary case. A breather hose was attached, running down the left side of the rear fender. Three small drain holes in the crankcase wall, near the front sprocket, set the primary oil level.

Yes Sir did that No filter and a lot of black slick there .Machine has been converted to take an Emgo Filter
AI says Emgo 10-26920 spin om filter
Not checked yet

Oil was medium dirty .. a 4 - 5 on an scale ten
And it seemed to be the right volume coming out.

Took the carburetors off and cleaned overall OK one Float valve seat was a bit Black cleaned it some '
Painted the short intake header with silver paint
De greased and cleaned when carbs off Toothbrush or a bit larger
Weird looking nuts difficult to tighten for holding the Carburetors
Had to make one new gasket .But recused the other

The light switch seems worn out The one sitting there is common for mopeds here Says Germany on it.
So Mr Lucas is acquitted -- free on that one.

I did pour in a bit kerosene for the fun of it Dont think it made any difference

And Polished some .

Tried to order a replacement License plate without extra holes and dents dirty. Dont cost much and gives an immediate impression to onlookers
that bike is being taken care off

But could not do it --- the paperwork for owner transfer takes some days .I have to be registered as owner before it can happen
Dont have any insurance either -- Mandatory Will wait until service is worked through ... full service .. everything Quick to do.insurance
On the phone
So far so good .I did notice that the nuts and bolts often was not tightened much Better so than to much but felt strange :not looked in the manual if it is to spec

Well this is a cool new thread I had not noticed before. Congrats on the nice acquisition Jan P! I find myself thinking about getting an old Triumph once in a while but not a high priority. Old bike prices are falling in this area though, so maybe one day...

This is my 2025 Tiger 900 Rally Pro, sporting the new hard cases I picked up in the spring. I love this motorcycle. If a motorbike could be a Yukon or Suburban with leather interior, this would be it. 13000 km now since April 2025. The new cases worked out well in the rain on a trip to Calgary in June. The top case is a $100 Pelican Case for pistols which I bought at Canadian Tire and adapted to the bike (used to have it on my DR650). Apart from tire change, the bike is stock and will remain so. I'll use these hard cases on the road but likely continue to use the soft bags I have for extended dirt road rides.

New tools from Lois Germany ca $ 50 + freight on sale looks as a Bargain ---open wrenches ca 25 $ locally Not many have them except specialist and then expensive
A new oil plug with mesh filter that was missing on order .. also ca $ 50
New Licence plate here and the Paperwork Ownership here
A Lightswitch ordered not stock used for mopeds back in the day. Have the functions
Valve play next and ignition timing
I caught a cold, other things got in the way, and the weather turned worse—but a bit more will happen this year.
Fixing the Stock handlebar switches can come later .. Maybe small microswitches inside
Or if feel rich order in England £ 60 a piece + freight and tax.
Not sure yet about the engine status

Personally, I wouldn't bother with 1970s handlebar switches. They were dreadful. I would go for a more modern switch assembly like Domino or similar.

Of course, it's different if you want to keep it like a stock bike.
Thank you I appreciate the input Experienced input .. I like stock and they are solidly built on the outside . But Maybe other options are better
But the bike looks better under the dirt than I believed Buying it .

I bought it intending for it to be a classic biker’s machine—complete with leaks and dents, like the ones my friends had—but so far, it seems better than that underneath the grime. The seller was more into American cars; he hadn't ridden it much or polished it at all, even though he’d owned it for years.
It's still early; there could still be surprises—there usually are.

I found some cheap alloy handelbar switches, undoubtedly Chinese, to fit to my Royal Enfield Bullet.

Replaced the handlebar light switch the replacement did not look the same electrically inside
Could not figure it out how to connect
I did for once make a paper sketch taking the old one out what color went where but had misplaced it so the replacement took 3 hours
looking for the sketch finally found it and i started to go better. Dropped screws and almost everything made problems.

New Oil plug with the mesh installed

It is supposed to be Boyer Bransden ignition but could not find the box before dark .Need to look inside where the Points would be if no Boyer
Not found a fuse either which needs to be there this being a + ground one day something can be hooked up wrong.
Wiring looks in fair state or better but are not clamped .. Some service on connectors .. I believe will be enough

Took the tank off se if electrics there :-- And for valve check turned out what looks as coils is under the battery box which is out .Some paint here and there
and cleaning is needed.

Had plans to empty the tank but had no place to pour the gas .Have to wait ... Works i progress still over + 10 C
 
Opened the cover and there was the Points aka no Boyer Bransden Installed
Looked unusually dirty in there . 4 -5 on a scale 10 First impression points not worn but will most likely replace soon or get a Boyer setup
Fresh with coils. .this can affect the slightly hard running on the top end and sooty plugs. difficulties to start
Valve play next
