Tiger Cubs

London Zoo – this week saw the arrival of a pair of precious Sumatran Tiger Cubs. And I thought my Cubs awakening was neat, but this is way cooler! Melati is the striped mother.

You’ll wake the neighbors!

The Moggy – Tiger Cub takes her first tentative, and loud, paces along a Chicago alley. Rough engine but the gearbox shifted smartly up and down a couple of gears, clutch action light. Who says we can’t start having fun with this bike?

Hear Me Roar!

The Tiger Cub gave its first yowl tonight! Engine back in, oil lines and ignition reinstalled, exhaust pipe plumbed. A few hicks with ground but once that was disconnected an easy hoof on the kickstart and a healthy bark. A bit a coughing and spluttering. But hey! “It’s Alive!”

‘Gin ‘n’ Tonic

Gearbox buttoned up this evening. Smooth kicker action and crisp changing ‘clunk’.

Just need to put on the head with adjusted valves then drop it back in the frame. Hopefully get a firing soon!

Open heart surgery…

Ok, so I bit the bullet and opened up the engine. Trying to accomplish this without the guts spilling out. Well the cam pinion gears were synchronized at top dead center, and the valves are now snug with a smidgen of clearance, well ten thou clearance. I could use a fresh splined gear lever spindle…

Valve Job

Well, I think I may have worked out the reason for the Cub woes: the valve retaining collar was of a type with a high rim which interfered with the rocker arm action. I dug out another type which provides excellent clearance. Top photos show two types. Fitted valves back in all looking tickety boo.

It’s Alive! Not!

Not a peep. No bark, non-ignition. Looked at valve timing, ignition set-up; workshop manual settings were followed … And still no chirp. Here it sits in Deans garage with big brother Bonneville sitting nearby.

I took the cylinder head off and perhaps the valve seats have exceeded recess allowance so the rocker arms bind against the valve spring collar perhaps keeping a peep of valve open and hence zero cylinder compression…

Yesterday the Cub emerged from its formative hibernation. Though it didn’t kick-over due to a possible ignition timing issue it sure looked good in the sunlight. It was loaded onto Deans truck – well we’ve seen a bike in the back of the Ranger before…

Pipe Dreams

Oil Bag – with some bracket fabricating tomfoolery the Cubs oil tank is finally attached to the frame. The exhaust pipe slotted into its rightful position snugly ready to pop-pop-pop into action. 

Weather permitting we may be firing it up tomorrow!

Oil Bag 3×3

The Cub – a high exhaust pipe routing is creating a bottleneck just under the oil tank. So some on-line investigating the various oil tank mounting lets me see how to get the engine oil feed and return pipes snugged behind a hot pipe. I think I may have a solution: mount the ‘oil bag’ higher with a tab extender allowing the lubricating gubbins to function.

The Mighty Mini

Race Day. Pack the car we’re off to the track. Well if your car is a classic mini you’d better make sure your Moto is a lightweight one: here they’re toting a Triumph Cub in the boot door. As needs demand!

Did I ever tell you I passed my driving test in a Mini?

Cellar Door

A two word noun that has been declared to be the most beautiful in the English language. Its phonoaesthetic quality was heralded by Edgar Allen Poe as a word whose sound (euphonic) is more sonorous than its meaning. 

Well I need to get my act together soon as the Cub nears assembly completion and needs to escape from its confines through a metaphorical Cellar Door…

Sit your Ass down!


 The single seat for the Cub needed some new padding. The foam under a clean original cover was starting to fossilize. I took said cover and seat pan to the local fabric and upholstery shop Vogue Fabrics and has some fresh plump foam trimmed to size.  
I like the special saw knife used to cut the blocks of foam. Once home I reclipped the piping edged cover back over its new filling and a perch to rest my tush is done.
