This page will chronicle the progress from start to finish the building of a highly modified 1971 Triumph TR6C . It is a parttime project that has been spread out over a few years.
In 1994, I worked for a motorcycle shop called SKELTON BROS. I was head mechanic. The guy who came by once a week and filled the vending machines was facinated at the custom bikes we were turning out. He wanted one real bad. One day, a man that worked out at the local Renaissance Fair brought in an old Truimph that didn't run but the engine still spun over. It had the stock squatty OIF frame with this super long front end on it with the stock rake. It had the ground clearance of a dirt bike. Bill bought that bike with a New York title for a song. The vending machine guy then made a deal to buy the old Trumpet and build it into his dreambike...
>>>>>>>> and so began the Tri-Ster >>>>>>>>>>>>>>>>>>>>>>>>>
The guy talked with me about what he wanted, and the bike he had in mind was a low, lean, stretched street machine. He didn't want a hardtail frame. I set to work on an idea, and came up with the concept you see starting to take form here. The first thing I did was cut the neck area and add some thick wall square tubing & 1" round stock to stretch and rake the front end to level it out. Then I cut the frame rail for the seat completely out and rewelded
it lower on the oil tube after also cutting down the rear frame struts to accomodate this move. Pockets were
fabricated to handle Sportster Hugger shocks. Fenderstrut moumts were also fabricated, and everything was welded into place.
Still not satisfied, I cut the swingarm and added two 6" lengths of 1" round stock to stretch the swingarm 4 1/2". This also increased the angle on the shock absorbers and lowered the bike even more with the Sportster hugger shocks. Of course the brake stabilizer arm needed to have the front anchor moved back further. I chose this route, because the stock stabilizer was already chrome, and didn't want to fabricate one that would have to be chromed.
still workin on gettin the $$ to finish her up ... ~Suds

The vending machine guy was pleased, but progress was slow, because he was making small payments. Then he got married, and stopped making payments. So the Trumpet had a mechanics lein put on it, and I wound up buying it for what the shop had tied up in it. I hate not finishing something I start. The bike stayed in my back yard under a tarp for another 3 years. We moved into a house with a garage, and I decided that she had sat still long enough. Working on her has been a lot of fun. Can't wait to ride her.
The sheet metal of choice was a full length Fatbob fender that was modified to fit. A Sportster quickbob tank was chosen for it's style and ability to be rubber mounted. This feature was important because Triumphs do vibrate.A 3 light dash was included in the tank kit. A twisted chrome B-bar was located to match the twisted chrome Z-bar handlebars.
Sportster forward controls were chosen because they are available in a right side shift style for early model Sportsters. Still they had to be flipped upside down and swapped to opposite sides to make them work. The stock brake & shift leverswere cut down and holes were drilled &tapped so that the linkage rod ends could be bolted to them.
The bike came with Dogbone risers on a straight 7/8" bar through stock Triumph risers. The dogbone risers and stock risers were sold on eBay and the money was used to buy other parts. The stock Triumph top triple clamp has angled riser rests, so they had to be modified with a hand grinder to bring the new 5 1/2" risers away from the dash and more in alignment with the fork tubes. Any one who has ran the dogbone setup knows that there is too much flex in there and you can find yourself riding with your handlebars cocked sideways.
A Cowbell Horn was salvaged from a Sportster. The bracket was fabricated out of 5/16" cold rolled flat steel. Rubber isolation was done by using a heavy duty vibration isolator. Once it is C-clamped in place, it is ready to be welded.
Now she's together enough to be registered and inspected. Got insurance on her
through BikeLine.com. Note the brake linkage in the bottom photo. It's made out of some chromed #50 chain, and is rigged to where the more pressure that is applied
to the brake, the more it grips the brakerod. We're gettin closer to ridin her ...8-)
Now that she's registered and inspected , it's time to tear her all the way back down and finalize all welds and fill in all unwanted holes. Time to remove the rust and prime and paint her....Pics to come for this phase soon. Have this 750 big bore kit shown bolow on order from a shop in Houston, TX. Can't wait to feel how this makes her torque....8-)
The big bore kit arrived, but has yet to be installed. Funds and time ran short, so the project was shelved for awhile. A few parts collected here and there, that t has now changed, so it's back to work. The front end has to be romoved as new steering bearings are needed and the fork seals need replaced. Also time to to some polishing.
New Timken steering neck bearings and races were purchased from Purvis Bearing for about 2/3 of the cost from Triumph. As you can see from the photo below the lower inner bearing race was rusted on the stem and had to be ground to get enough relief for removal
The front tire was replaced with a new Dunlop 19". The silver paint on the heb and brake backing plate is of a good grade and hard to strip. With the use of a Dremel Tool and a small wire wheel attachment, in conjunction with paint stripper, the tedious process begins.
The polishing is accomplished by using a soft bristled brush attachment on low RPM with Jewelers Rouge. It is worked in till the mirror finish starts showing through the black glaze. Then it is wiped off and a miricle product called Gords Chrome & Aluminum polish is applied by squeezing some onto a clean red shop rag. Then it is worked in by hand till it turns black then allowed to dry. After the dry glaze is wiped off, the results are fantastic. This stuff works twice as fast with less effort on a surface that is already polished to restore a showroom finish.
The rear wheel was refitted with a dunlop 16" Gangster White Wall tire. A new speedo drive was purchased from Southwest Choppers in Dallas, TX. Great bunch of guys, and I recommend doing buisiness with them, as they are prompt on returning emails. The While Wall looks good if I do say so myself.
