Default seize?

Greetings- Newbie here of a few days (to the bb and 1.5 weeks to my '69 Triumph T100)

I took it out yesterday and when I hit about 75KPH I felt a slight tugging (almost like the gas was not flowing properly). I increased the throttle and felt/heard a pull- suddenly I lost power and the engine shut off almost immediately (stopped running). When I pulled it over- i tried to kick it started and the kick was seized. A bit later I was getting towed and we gently pulled it into gear. This "unfroze" the kick but now when I try to start it and kick it I get a loose compression noise(see this link for a video) . I noticed that my throttle ring on my handlebars had been turned upside down and of course the cable was very loose- both at the ring on the bars and where it leads into the corroborator. Wondering what happened and what do I do?
I also noticed that my battery (of 1.5wks) was a bit expanded or swelled. Dunno if this is connected.

I wouldn't kick that over anymore until you pulled the head and had a peek in there...

Sounds like a seize. You need to find out why, as well as how much damage it did. As Benway stated- don't kick it anymore, til you look inside.

Listen to the man. He's a doctor. The video made me cringe.

Short version? Shit sounds broken. Take off the cylinder head and peer in there. If it's what we suspect, it will be obvious. If not, take pics and post them here.

This has actually been sitting for years
I'm going to open it up (gulp) and see what's up. Sorry to be so rudimentary but anything I should do or be careful of when removing this?

Thanks all

For starters, pull the spark plugs and shine a light into the cylinders to see if you can see any carnage on the piston tops, if at all.

I have a wonder on if this motor just had a fresh bore job done to it (new Pistons)...???
Personally, my guess is he's about to learn how important a clean sludge trap is.

+1 on that.

And...never trust a "sitting" bike.

Newtriumph,
I'm picking up that your new to wrenching on motors....If I'm correct, STOP....
Do a search on here and find a manual, read this cover to cover and reread it untill you know it pretty damn good.

Now, with this knowledge, take your time and start the disassemble. Get yourself some of the zip lock sandwich bags and as your taking things off, bag them and mark what is what. If you have questions as to if a part is good or not, post a pic on here and someone will tell ya. Theres a wealth of knowlege on here, use it. Good luck.

Great advice D.

The others have said excellent comments also.

Please take your time and inspect everything closely. Most problems can be found with a good visual inspection combined with the understanding of how each component and why each component works.

Study and ask questions, take pictures of it assembled and as you remove each piece. Remove big pieces, like the head. Set it aside and remove the next. Then inspect and disassemble the big pieces, one at a time.

I cover my bench with white butcher paper and lay it out like the exploded view in the assembly manuals. Small parts have a harder time missing that way.

I know it sounds tedious, but for the first time getting into one of these, you will be grateful you took extra care, when it goes back together.
