The Swallow

Jet Fighter – this day in 1942 saw the Messerschmitt ME262 become operational. It’s shark-like appearance and brute speed must have been an eye opener for the allied pilots. A far cry from the bubble car a decade later as seen in yesterday’s posting.

ME109 successor 

Bubble Trouble – this bright red three-wheeler beamed at me by the side of the road today. I had to screech to a stop, park nearby and get some snaps. It’s a Messerschmitt car KR200 or Kabinenroller. Not being allowed to manufacture aircraft after WW2 these were Designed by Fritz Fend with Willy Messerschmitt only putting his name on them. 40,000 were made between 1954 and 1965. The streamlined appearance with fuselage inspired body gives it a futuristic look even today. Flying cars anyone?

Alas…

City of Brotherly Love – cool photo of a busy motorcycle workshop in the near north of Philadelphia. Yorick & Sons Moto is a full service repair and build garage. Located in the blue-collar hipster neighborhood of Fishtown. http://www.yorickandsons.com/

Sticky Rubber

Cornering Prowess – it all comes down to your tyres. This watercolour illustration has flight swept into its brushstrokes and the rider sure has a confident grin mid lean. Not sure about the little acorn touk he has perched atop his noggin.

Petrol Head

Gas Up – quick fueling stop mid-ride. Filling with 93 octane. The old valve seats would prefer leaded to protect them from regression but lower compression and trying to avoid ethanol additives help too.

Tickler 

Amal – the engine is getting a new lease of life. I have acquired a pair of brand spanking new carburetors to invigorate fuel delivery making sure the motor has plenty of oomph through the rev range. These classic concentric carbs are nice clean castings, good materials, serviceable parts, anodized slides, and are practically a bolt-on and ride item. I’ve had to carry out a couple of slight adjustments for my bike but hopefully I can put the air cleaners back on tomorrow and connect the fuel tank.

Roadside Maintenance 

There’s a’wys summat! When your machine is reaching half a century in age even a 100 mile jaunt can uncover a mechanical snafu. Here Dean finds that the small timing pin plug behind the cylinders decided to jump ship somewhere between Glencoe and Antioch. Upsetting pressure and spewing a fine mist of oil onto the frame he had to get a 1/2″ bolt from a Napa auto parts store to make a temporary fix.

Knowing your bike inside and out means these impromptu repairs just delay an otherwise smashing weekend ride…

Triple Power

Cubed – when Triumph emerged from the near fatal flatline in the nineties they used a modular engine design that could be shoehorned into different models. Good sturdy machines that still hold their own on the road. The Adventurous Tiger, rippled Speed Triple, and a speedy Sprint offered a British badged moto with doughty engineering.

Boiler Suit for Geordie?

Helpin’ Hound – I’ll just put this image here…

Pi

π – defined as the ratio of a circles circumference to its diameter, this mathematical constant is ubiquitous to the universe. It also has meaning for the motorcycle from Wheels to discs, gears and cogs, dials & caps, and lights.

Woden’s Day

‘Ump Day – What do you get if you cross a Triumph and a Greeves? A Grumph! Perfect name for a mutt; even with immaculate pedigree. Offered the choice of a Rickman Metisse or this… pretty hard choice.

Liquid Engineering 

Oiler – here’s a stunning graphic advertisement from a late sixties magazine with no. 1 Gary Nixon powering his Triumph flat tracker in a somewhat psychedelic manner. Castrol

Brr a bit parky out there…

After last weeks brush with spring-like 60’s temperatures the true nature of February claws its icy talons back into our locale. We’re experiencing close to single digit wind chills right now. An inventive Triumph chopper owner takes snow removal into his own hands with this street-sign homespun plow. No snow here right now… perhaps if a whiteout beckons I’ll finagle a shovel attachment onto the Cub…

Giddy up 

Gearing Up – the work involved in stepping up from a 19 to 21 tooth front sprocket required some notching to be done to the case so the larger diameter gear could be slotted into the primary drive axle. 21 equally spaced grooves. Whilst I was in there the clutch was renewed which gives an very noticeable grab when throttle is applied. The gearing give about 12% extra wheel revolutions for the same engine speed.

Hacky Dorty

Swarfega! – working on old motorcycles can be filthy work. I always find myself with oil ingrained hands even after a minor fuss of the bike. When doing the sprocket there was two chains to deal with, a road crud encrusted underside, some aluminum filings, and general grubbiness.
