I am getting my 1967 Triumph Bonneville ready for a show in Indianapolis later this month, and I have a few questions concerning "originality" that I hope some of you can help answer. The vin # for the bike is DU48683, which is a Monobloc carb model. I do understand that 1967 was a big change year, so bikes could have different equipment. Here are the questions:

Did the T120R Bonneville with monoblocs have the choke setup or the plug/bolt in the top? My 1967 brochures show no choke for the Bonneville, but I have seen supposedly stock bikes both ways.

Did the bike have the flat pancake style at the rear of the air filter or the dish type? If it is the flat style, did it have the "wash in petrol" sticker?

And lastly, which direction did the front of the horn face, timing side or primary?

The show I am attending is the Cycle World Rolling Concours show that is being held in conjunction with the Indy GP races at the Speedway. First you ride 50 miles around Indy and then have your bike judged. Maybe I can get a lap or two around the track!! wink

Ok, don't count on this as being gospel, it is based on a pretty stock 67 that I purchased some time ago...

It did have stock monos with the choke setup.

It also had the flat style back covers on the air filter covers, but I don't remember the decals.

I really don't remember the horn facing, but I think pretty much all had the face toward the timing side.

The 1967 US parts book carburetor illustration and data for the T120R and T120TT show the carburetor with the 4/137A blanking plug and no choke cable is illustrated for these models on the cable page.

My 1967 is in the 50,XXX and has Monoblocks w/o a choke, just ticklers. My guess is you may find considerable variation across the model year.

Yep, it's a changeover year from monoblocs to concentrics, from gray-topped seat to all black, from Aubergine & Gold to Auber & White, among other "invisible" changes...

The Nov. '67 over of CW mag. shows a brand new '67 T120R with the horn facing the drive side. I bought a new one in mid 1967, it was Aubergine/white, it did not have an air control, it came with monoblocs and pancake air filters w/flat black end covers and an all-black seat, incl the bottom welting. I still have it.

Thanks so much for the help! I will go without chokes and switch to the pancake (flat) back plate on the filters.

I will share that in 1967 after my brother came home from Vietnam, he took me out to his garage and showed me what I thought at the time was the most beautiful motorcycle I had ever seen. I was 10 years old, and yes, it was a brand new Bonneville. Unfortunately a couple of years later, the Bonny and a Honda got tangled up together and the bike was totaled. Whatever the case, the memory of that Bonneville in the garage will always be there!!!

lit67, I'm not "locked in" just yet, but I'm trying to arrange things so I can do the CW rolling concours. If so, I'll be at the welcome deal on Thurs. night. I'll look for you if you let me know how to recognise you, other than a guy with a 67 bonneville. Jack
