1966 Triumph T100SC Jack Pine Enduro Model

For 1966 Triumph continued to offer the T100SC for the first half of the season. This bike is a fine example that I purchased earlier this month. Showing just 5075 original miles this machine is a stunning example of how they left the factory.
These lightweight 500's were nicknamed the Jack Pine Model by the factory due to their successes at the Jack Pine Enduro in Lansing, Michigan during the mid 1960's
Finished in Sherborne Green with Ivory stripes and fitted with aluminum fenders.
Two into one siamese pipes provide the ground clearance necessary for off road exploits.
They came with the battery less Energy Transfer ignition system which was frowned upon by many but I don't have anything bad to say about it. When set up properly they work great. 
Standard road machines included a Side Panel which housed the switches that were not needed with the E.T. set up so the cover was eliminated on the off road models which also left room to bolt on a "Q" Air Filter box if so desired.
1966 Fuel tanks saw the introduction of the new "eyebrow" style tank badge. This tank was only used for half the season, it was replaced with the more common 3 gallon tank making this a very hard to find tank if one needed a replacement.
The mounting arrangement was also unique for this set up.
No tachometer was fitted, just the single speedometer with a horn button on the right and kill button on the left.
This photo clearly displays the Lucas E.T. Coils and electric Horn as well as the original Champion plug caps.
Italian Gran Turismo grips were fitted to the 7/8 Handlebar.
Just 5075 original miles showing on the speedo. The previous owner purchased this bike in 1969 from his buddy who's son had purchased it new, he went off to Vietnam and never returned so the bike was sold in '69.
It resided in a heated garage in Encino in Southern California, because of this it is corrosion free, no pitting or rust which is fantastic,
Living close to Mulholland highway, the previous owner putted around on this famous road that runs through the Santa Monica mountains. He told me of visits to Bud Ekins shop down on Ventura Boulevard in Sherman Oaks, Bud did a service on it back in the day.
Although I must point out that the bike is not without a few battle scars, there are some scratches here and there with a couple of small dings in the tank and front guard where he had the odd spill. Just adds to the character and authenticity of this unrestored machine.
Fuel is supplied by an Amal 376/273 Monobloc Carburetor, I had to replace the old fuel lines for safety as they were rock hard and brittle. 
Lovely to see an original exhaust system as the lines flow beatifully.
Small amount of scuffing at the tip of the Silencer.
It is said that the SC stood for Sports Competition. 
Ivory tank graphics were lined in gold pinstripe.
Drive side showing Coil and Condenser arrangement.
19" Jones front rim fitted with the original K70 3.50 Tire, parts book states a 3.25 but the reality was that they came with the bigger 3.50. The rear rim is Dunlop with a 4.00x18 Tire.
Black plastic tool tray fitted, 1966 and 1967 twins also came with grey versions.
Smashing patina on the aluminum fender.
Battery less ignition meant no need for a battery tray.
Crankcases are so clean, hardware untouched, the joy of a low mileage unrestored bike.
Lucas headlight was the smaller 5-3/4 unit which housed the light switch and dip switch. Small dent on the Rim.
Choke was operated by a push down lever instead of the more common cable and bar lever.
1966 was the first year that the "Triumph" logo was added to the back of the dual seats. This seat has survived very nicely. Shame that most restored bikes have aftermarket seats that really don't look the same.
Nice to see a tidy Engine with no broken fins.
Wheel rims are both lovely with the original spokes, no stainless here.
Still has all the cables it left the factory with.
The fork gaitors also had to be replaced as the original were rotted, these and the fuel lines were the only updated items.
Hubs and Rims in great shape. 
Fitted with all the necessary items to be street legal, here is the Lucas stop lamp switch mounted as standard to the chainguard.
Steering damper knob was a Triumph staple since the introduction og telescopic forks.
Gorgeous Fuel Tank.
What a great bike!
As of time of writing this bike is available, asking $12500.

1956 Triumph TR6 Trophy Pre Unit Desert Sled


During the summer of last year I got a lead on this old Desert Sled that had been sitting for many years, things like this I cannot resist so it was up to Visalia to do a deal and bring it home. 
It was my intention all along to not restore this bike but perform a complete mechanical restoration. I wanted to retain the original patina but also understood that the mechanics would need sorting.
For once in a long time I found a very nice rebuilt engine inside. Upon disassembly I found new Bearings, Pistons, Valves, Guides and so on. Although surrounded by new parts the Crank appeared to have not been disturbed and after separating the 3 parts I found a Sludge Tube 3/4 full with hardened sludge. Why the previous engine builder went to all that toil without getting into the Crank is beyond me. Anyway, all cleaned out now and rebuilt with a new set of pricey Crankshaft Bolts.

The Primary Chaincase was empty inside so new parts all round. New Rubbers in the Shock Absorber.
All 3 Sprockets were replaced with new Drive and Primary Chains. Check out the Webco "layover" Sprocket. These were bolted to the original Sprocket via 5 Bolts. Both front and back Rims were destroyed by previous desert abuse and rust so both had to be replaced, both laced with Stainless Spokes and fitted with new bearings and brake shoes. The Forks were frozen so they were replaces with new bushings and seals. At this time the Steering Head Bearings were also shagged so they were replace as well. Pandora's Box comes to mind.
The original project came without a Seat. The obvious choice was a Bates so a dedicated search to find one was initiated. 
The seat is mounted via the stock front mount, rails welded to the seat pan allow the seat to sit on and be supported by the Subframe. There are then a pair of brackets at the back end bolted to the bobbed rear Alloy Fender. It is due to these rails that it is positioned where it is. This is the way Bates intended it.
When I found this Seat the seller provided the period Bates Catalog page showing this seat which is labelled on a tag underneath #3258 which as you can see is actually specified for the 54-59 Triumph Swing Arm Frames. Very fortunate to find considering the many different Seats they produced. Unique in it's white leather cover which still wears a BATES stamp in the back.
Webco sold these Air Cleaners, they were manufactured by Torque Industries in the 1960's, a company in North Hollywood. Essential to cope with the dust in the desert.
No pipes with the bike either so the choice was easy, Bud Ekins replicas. Not sure how long ago the unit 650 top end was fitted, the Head is from 1966.
Throttle Cable routed upward. Stock 1" Handlebars have remained.
Essential for any Desert Sled it a sturdy Bash Plate to protect the Cases from rocks and such like. This one was made by Bast Brothers who were a Welding outfit in Van Nuys here in SoCal. Tons of drilled holes to lessen the weight of what is a heavy old piece of steel. The Side Stand lug has to be removed to use this.
Triumph did not produce folding pegs until the 1960's so desert racers converted stock pegs to folding. Bates rubbers were screwed in place.
Amal Carburetor top cover has a waterproof cover, pretty pointless in the desert but it looks the part.
Original Lucas K2F Magneto was sent out for reconditioning. It did spark but I have leant from past experience that any old Mag will probably fail sooner than later. Once rebuilt they are extra reliable.
No Generator needed with no lighting so the Generator hole in the Crankcase is plugged with a cover that the factory originally supplied with the Race Kit
Out to the Dirt to for testing transported by my trusty "59 El Camino bike hauler.
