1966 Triumph T100SC

Tank badges came in the mail! They have a nice patina that matches the bike I think. Waiting on the proper British Association thread screws to arrive so just a test fit with skinny screws in the holes for the pics. Woot!

Thanks! I’m super pleased. I think I’ll install the new fenders next and see how it looks.
 
So the rear fender is pretty beat up as I've said previously. There is a metal hoop that it bolts to that was also pretty beat up. Once I had the fender removed I could see more clearly that it needed to be straightened out some. Also the foot rests were bent to hell, so off came all these parts and with a little persuasion they are all much better.

I'm hoping to find someone locally with an english wheel, or a pneumatic planishing hammer who can help me clean up the rear fender and I think I'm going to also trim it a little bit at the end as well. If I cant clean it up I'll install the new ones, but I think they are too clean for how the rest of the bike looks.

Here is before and after on the rear hoop.

....I know someone that has both but they are down in San Leandro....

Hit me up.
 
:thumbup. Thanks!
 
So the mounting hardware for the tank badges arrived today so I got them installed! Super happy with how they look! I also took a stab at pounding out the big dents on the rear fender and getting it to sit straight. I got the tail light mounted and realized the wiring was damaged so ordered a new subharness for it. I'm amazed at how much is available for this bike and how cheap everything is. The harness was $12.95 delivered! So still have some work to do on the dents but I am happy with the improvement. Also need to weld up a couple cracks in the fender. Woot!

Spent more time working on the bike today. I adjusted the valves, intake were a little tight, and exhaust were spot on. Put some ATF in the primary and replaced the fuel line with clear that has a thicker wall than the stuff I was using that kinked. Also removed the chain guard because it was rubbing on the tire a bit and I need to make it fit better, and took the bike for a spin around the block. Unfortunately it was running on one cylinder again and it was pissing out the atf in the primary.

So I ordered a bunch of new seals for it and ripped the primary cover off. Once I got in there I think I found why it keeps running on one cylinder intermittently. The wire bundle coming off the stator was contacting the primary chain and one was partially worn through. I pulled out the clutch plates and they look good so that was the good news. There was also some water in the primary, I assume from me pressure washing the bike. Turned the ATF into a milkshake!

So to replace the seals on this side, the stator rotor and clutch basket have to come out. This will also give me access to the main shaft seal on the engine side so I'll be replacing everything. I also noticed while looking under the bike that these same wires coming off the stator exit the case and run down under the engine to the frame and it looks like they are also contacting the drive chain, so I'll be cleaning everything under the engine, removing the harness and I'll go through it to make sure all the wires are good and routed properly so this doesn't happen again. This could be the reason this thing was parked 40 years ago and never ridden again. :thumbup

So I made a little more progress on the Triumph, but also took a huge step backwards. I guess it wouldn't be a proper 1962siia vintage project without major carnage to deal with... :laughing

So the primary oil was leaking like a sieve so I knew there was a problem but I didn't expect what I found after removing the clutch basket. It seems the drive chain snapped at some point and took out a big chunk of the case! They filled in the void with silicone. Not sure how I'll go about addressing this issue. Seems like the options are to replace the cases which is a bummer, or to buy a used left side case, cut out a piece and have it welded in by a pro like Dennis at Norman Racing. I'll probably take the bike there to get his opinion and go from there. Ugh. Here are pics of the carnage for your viewing pleasure!

wow ... pretty spectacular. : |

had a KLR buddie where something similar happened (banancer-chain punched hole in cases) ... he used epoxy/jb weld ... epoxy/silicone does not sound like a quality-1962siia-standards solution, though.

nice to think about that hole welded up ... :thumbup
 
Do you think this might be one of the reasons it was parked way back when?

Well they definitely tried to plug the leak with a big blob of silicone so I’m not sure. I’m sure it lead to the wiring/spark issue and it furthers my belief that this thing was ridden hard by a young man and put away.


So a friend recommended I go for a ride to think through the issue. It was a great idea and I rode through west Marin. Headed west riding his r1200gs and back on his r50/2 (?). Super fun ride. Thanks Derek!
 
Ok so spent some time at Norman Racing this morning and a plan is in the works to repair this case. I'll be buying a used left side case and pulling the motor and then Dennis will be doing the rest. :thumbup

Woot!
 
Dang tough crowd! :laughing
