1966 Triumph T100SC

[1962siia]

New coils, capacitors, and spark plug caps came in and I got them installed, and went through the ignition timing and the bike is running really well. Did another carb cleaning and lowered the needle one step and that really helped too. New fork seals and gators are on order and arriving early next week so I'll be ripping the front end off the bike. While I'm there I'll service the steering head bearings too. Next up new tires and tubes and wheel bearings.

Any thoughts on vintage dual sport tires? I went with shinko trials tires on the Harley and they were halfway gone after the moto melee so hoping to get something that will last a bit longer. Thinking about shinko E804/805 big block tires. I think they will look cool and for my 80/20 dual sporting I'm sure they will be fine. Not sold on these yet so weigh in if you have any suggestions. Thanks.

I ran a Shinko 244 rear tire on this past Baja trip. It’s a 50/50 tire. Worked well with my 250.

 

[1962siia]

I forgot that Eric. I remember you saying they worked well. Thanks. PS- $76 for the pair!!! Woot!

So spent the evening removing the forks. I’ve seen horror videos of having to bash them out with a sledgehammer. Mine came out pretty easily. Some minor surface rust but it was easy to get the forks off. Now I’ve got to buy the special pin spanner to remove the fork seal keepers. I’ve seen a video using 1/4” ball bearings and a vice so may try that instead.

Steering head bearings had absolutely no grease at all. Managed to not lose any of them when I dropped the stem out. May look into tapered roller bearings instead. Not sure yet.

Stoked you are going deep and doing it right the first time.
I hate hearing "I put gas in it and luck me it started and runs, I'm off to ride the piss out of it" when people get their hands on an old bike that has been sitting.

That bike is the very essence of BADASS!

Yeah I'm glad too especially after finding no grease in the steering stem!

:laughing Yeah I think this ones a keeper! :ride

Thanks guys!

Definitely replace the steering head bearings. Hard to believe it took so little to get it fired; whoever prepped it (somewhat) before storage gets some props.

I’d clean and polish everything and stick with whatever patina is remaining. That’s a helluva find and project!

Nice... not sure how I missed this.

Right footer club rider!

Enjoy the new old ride.

Daniel, that is awesome! Now I know why you've been neglecting the 950...

No doubt I'm lucky they did what they did. Steering head bearings are fine and they dont make a tapered roller bearing kit for my model year. I cleaned them and the races and reinstalled with fresh grease and its happy.
Yeah I'm planning to polish the aluminum and chrome and keep the rest the way it is (except I'll buy tank badges for it).

Thanks man!

:laughing Hope I didn't procrastinate too long! I need that bike for Weaverville. Cant believe how slow the parts place I chose was to ship my parts!! Looking forward to riding with you this weekend! :thumbup

can't wait to see a pic with the new headlight ... :ride

one nice thing about old Triumphs
(or any vintage bike, really, as you know)
is they polish up really pretty ... :thumbup

The headlight that came with the bike is definitely not the original unit. I'm having trouble actually finding the right one so far but I'll keep hunting.

 

[1962siia]

After waiting on parts, a barf rally, and a visit by the in-laws, I finally made a little progress on the bike. I found the proper headlight too! I got lucky and it was local in Sebastopol. It will need some cleaning up, actually a new trim ring, but its the correct unit for this bike so I'm happy.

So I replaced the fork seals, cleaned up the fork tubes, replace the front brake pads, wheel bearing, tires and fork boots. Unfortunately when I got it all back together the bushing dont feel right so the whole thing will be coming back apart for new tubes and bushing. It will be worth getting this right I think and the parts aren't horribly expensive. Should have just done it the first time, but I've installed and removed the forks a couple time though this process so I think I can get the whole thing done in a few hours tops once the parts and tools arrive.

That brings up my biggest complaint about this bike: Special tools. This thing needs alot of them. LOL!

Here are pics of the bike with the new headlight and front tire. I went with the shinko 804/805 although I may go with a different rear tire. Not sure yet.

 

[augustiron]

Nice. What's wrong with the fork bushings? Too tight or too loose?

 

[1962siia]

When sliding up and down they feel stiff and dont slide freely all the way up and down, and the lower legs I can see and feel them moving front to back when pushing up and down of the forks with the brake on, suggesting the bushings are worn. I may not have had every thing lined up perfectly but the lower part being able to move like that is no bueno. Also noticed when putting back together the forks had to be pushed together to get the axle to line up properly so things probably aren't straight which would explain the stiction I'm getting. I didn't check the tubes to see if they are straight. Anyway new tubes and bushings and it should be fine.

 

[1962siia]

Ok finally got back to this bike today. All the fork parts came in a few weeks ago but life has been getting in the way of motorcycle fun. This morning I ripped the front end apart again and replaced the fork tubes and all the bushings. I confirmed that the old tubes were slightly bent.

The swap was really easy and quick once the forks were off the bike. Upon reassembly, everything lined up perfectly and the stiction I had is completely gone now. Its super f-ing hot up here today so I'm done until things cool down but I suspect I'll have to take a victory lap around the block at some point. I wont go too far because there is still alot that I haven't gone over but I want to feel what its like with proper forks and tires. Woot!

Heres an old vs new pic of the fork tubes and the bike when I was done.

 

[auntiebling]

nice!

where did you get the new tubes?

 

[1962siia]

I think it was The Bonneville Shop. I've been getting a lot of parts on ebay too. Nothing is that expensive compared to KTM parts I'm used to buying. Tubes, bushings, and seals were around $200.

 

[auntiebling]

lucky
maybe i need to move to antique rattletrap bikes.

i have a cbr900rr front end (personal thing) i want to graft onto something much older. tubes are heavily pitted. replacement tubes are ~$toofuckingmuch each.

 

[1962siia]

Getting pretty close to having this thing ready to ride! Replaced the rear wheel bearings and rear brakes this weekend. Also cleaned up the wiring for the new coils and swapped over the wiring for the headlight from the old bucket to the new one. I attacked the seat with some all purpose cleaner and its looking much better than it did before. Also installed new petcocks along with new tank pads. I've got some tank badges coming in the mail along with a new headlight trim ring, some tail light parts that I need, and all new foot peg, foot lever rubber pads, so the list of needed parts is getting shorter.

It's starting to look legit! It came with some new reproduction fenders. I love the look/patina of the front fender but the rear is pretty dinged up and the tail light ripped out of the fender at some point so I think I'll be swapping out the fenders too. Anyway here are some pics of how it looks today.
