1978 Triumph T140E

For sale bitter-sweetly is my 1978 Triumph T140E Bonneville. If you're looking for a stock 70's Triumph you'll find nothing more road-ready and complete. First kick starter. Bike is the rare Tawny Brown over Gold color scheme. Clear Ohio title in my name. Odometer at 13979 mi. The 1978 T140E was released in the United States with a slightly modified carburetor tuning as compared to the British T140 to meet strict US EPA import requirements...thus the E at the end of T140 for "Environmental". I have converted the carburetors on this bike to the original T140 specs and the performance increase can be felt. The Amal MKII carburetors have been completely rebuilt to those specifications using Brand NEW Amal parts ordered directly from Amal in the UK (for which I have all receipts). Beginning with the specifications of that conversion: 210 Main Jets 15 Pilot Jets 35 Choke Jets #3 slide 3.5mm Primary Air Jets 2A1 Needles (set in middle position) .106 Needle Jets New Main Jet holders New floats with new Amal Stay-Up Floats New viton-tipped float needles New float bowl gaskets New Float bowl drain washers Brand new plunger choke assemblies!!! Originally the bike was tuned with the following components all of which are included in the sale: 200 main jet 2C3 needle 106 needle jet #3.5 slide 25 pilot jet 50 choke jet Both carburetors have fresh new intake rubbers (old ones are included) pairing them to the cylinder intakes and new foam rings between the air filters and carb intakes. For anybody who knows about tuning and troubleshooting the fuel delivery systems on these bikes having new choke plungers and air intake hoses along with the complete carb rebuild knocks out a lot of potential issues that commonly manifest due to part wear over the years. Boyer Micro-MKIV electronic ignition Dunlop D404 Tires Yuasa Battery Uni NU-3005 foam air filters. Recent upgrades: New Internal Oil Filter (mesh tophat) Emgo Dunstall Reverse Megaphone Mufflers (the pipes sing quite beautfully) DID Drive Chain New Engine Kill Switch New Lucas 3-way Headlamp Switch 2 New Emgo 6v Ignition Coils New Battery Seat Rubber New Foot Peg Rubbers and Grips New Tachometer Drive New Petrol Tank Steady Rubbers New Oil Cap with Dipstick New Rocker Box Inspection Cover Gaskets Wide-stance scrambler handle bars The only real modification from stock is the installation of an additional in-line oil filter. I chose the M.A.P Cycles replaceable oil filter. It is installed in-line between the oil pump return and the frame reservoir. This filter modernizes and supplements the bike's primitive wire mesh oil filtering mechanism and aims to prevent build-up of sludge within the notorious "sludge trap" (which requires the engine casings to be split and the drive shaft removed in order to clean it). It's a $99 upgrade that could prevent hundreds of dollars of damage. If you'd rather run it with the stock oil filter only for some reason you'd simply need to remove the MAP filter from the return feed and that's that. Recent Maintenance: Front master Cylinder completely disassembled and cleaned. Front Brake caliper disassembled and cleaned. Freshly bled and topped off brake fluid. Float height set ignition timing has been strobed valves set (.006" exhaust .008" intake) primary chain adjusted. Engine oil has always been changed every 1500 miles (I always use Brad Penn Grade 1 High Performance Oil with ZDDP) however I'd advise you to act as I do and change the oil/adjust the drive chain upon purchasing so that your maintenance logs are enacted immediately. Bike is always on a Battery Tender when parked at home and is protected from the weather by a car port and a Dowco bike cover. Extras included with bike: 3 Complete Manuals: Official Triumph Workshop Manual For Bonneville 750 and Tiger 750 Haynes 650 & 750 Twins 1963 and on Haynes 650 &750 Twins 1963-1983 Two New Replacement Oil Filter Elements for MAP oil filter 3 New Carburetor Float Bowl Gaskets All of the original Carb components for spare (needles choke assemblies float needles 200 220 230 and 250 Main Jet pairs floats #3.5 slides etc....) Two Rubber Carb Intake Seals Spare Taillamp and mounting bracket Spare Headlamp Pilot Bulb Spare Float Bowl Drain Crush Washer New Spare Condenser New Chain Tensioner Box of 30A Fuses Two Brand New Triumph Passenger Foot Peg Rubbers Spare Oil Filler Cap New Battery Tray Rubber 11 New Spark Plugs (7) NGK B6ES (4) Champion N5C This bike runs beautifully pulls strong sounds amazing for a T140 Bonneville and a unique look. As of right now there are no looming issues or maintenance due. It leaks the amount of oil (or less than) you'd expect from an old Triumph. Park it overnight after riding and you'll see a few drips on the ground. Please feel free to contact me with any questions that you may have.
