Ride it like you stole it

5030tta

It’s good to see our friend Carsten Conrad isn’t shy about using his bike as the maker intended. The eagle-eyed may notice the modern rubber which he prefers having covered around 1500 miles last year, often riding in company with more modern machinery. Averaging 54km/h over a 220km ride on back roads and through small towns hints at some serious throttle abuse.

Perhaps not surprisingly he is now looking for more performance from the motor: “The bike runs good but not yet enough”.  With a new piston, genuine TT90 head fitted with large valves and his own valve guides, the target is now 30hp. I suspect that it won’t end there…

I recently donated my own spare Amac 10MDY to a worthy cause but if anybody has one that they could pass on to replace Carsten’s Amal 27/013, please drop us a line to and we’ll put you in touch.

 

Brough Superior SS100 vs Sunbeam Beggs-Special

Amidst the deluge of PPI mis-selling calls that characterise life in the 2010s it’s a rare pleasure to pick up the phone and find Archie Beggs at the other end. Archie’s generosity of spirit knows no bounds and on this occasion the call would result in the fulfilment of one of this particular schoolboy’s dreams. The call started simply enough with the offer to have a canter on Archie’s 600cc Model 9/9A/90 based special. I already knew that this bike featured an engine from his racing days and so was obviously keen to try it for size. We arranged a mutually convenient time and I was just about to hang-up when Archie landed the sucker-punch : “and while we’re there, maybe we’ll get the Brough out for a spin too”

The day dawned cold and clear as I headed up the Wirral and I gradually became aware of an uneasy sensation in the pit of my stomach. I marked it down to the macro-consumption of the micro-brewed beer the night before. Ploughing onwards on the M53 I put the feeling to one side and instead concentrated on coaxing the last few mph from the little Honda Civic. On arrival we dispensed swiftly enough with conventional pleasantries and were quickly on with the business of the day. First out of the trap was the 600cc Sunbeam Model 9/9A/90 pictured below.

Sunbeam Model 9 9A 90

Nominally of 1932 vintage, the engine in this particular bike features a 600cc piston in conjunction with a Model 90 hairpin-spring head. The motor was put together in Archie’s sand-racing days and the pukka Amal 29/001 M90 carburettor demonstrates a clear sporting intent despite the valanced guards, pillion provision and lighting kit on the rest of the bike.

Also of interest is the fact that this is a single-port head design which some believe to offer better performance than the twin-port versions more usually found on the OHV Sunbeams. Something to do with exhaust gas velocity and back-pressures perhaps? Again Archie’s racing experience is demonstrated as the bike has been fitted with the later and larger Model 95-style front brake. Sunbeam’s Webb-type front forks have a dog-leg kink at the bottom which is required to make space for this improved performance brake.

Having been stood for a while, the bike was a little reluctant to start despite teasing with a few pops and bangs and so a quick shove down the drive was used to bring it to life without problem. I just wasn’t prepared for the civilised exhaust note nor the gentlemanly tickover that the bike settled into after barely a few minutes warming, expecting perhaps a more recalcitrant or cantankerous beasty. Thinking about this on the journey home it was really no surprise that Archie’s bikes always seem to run so well as success on the sand would rarely be achieved with anything other than a perfectly setup motor.

What was it like to ride? Smooth, powerful and comfortable were the overwhelming feelings once the bike was underway. The gears selected as well as any Sunbeam I have ridden i.e. a small crunch into first which then accompanied only careless gear shifts. It really felt like the sort of bike you could spend the day on and easily cover large distances in comfort. The motor pulls strongly in all gears which would make lazy riding a pleasure but once the revs rise it certainly picks up it skirts and becomes an altogether more intense experience. You could feel the extra weight over my own Model 90 for sure but this added to the sure-footed and stable feeling that the bike exhibits.

The uneasy feeling returned when I got back to the garage where the Brough was now waiting its turn to be let out of the stable.

I realised then that I’d never ridden or driven anything that was easily worth more than my house. It clearly wasn’t last night’s beer consumption but apprehension at the consequences of even a minor mishap on such a rare motorcycle. The 1927 Brough Superior SS100 is a true motorcycling icon with the powerful OHV JAP motor providing genuine 100mph performance at a time when few vehicles could manage half that. Little wonder that T.E. Lawrence used a string of SS100 Broughs to get his kicks. A bit of technique is required to start it so this was left to  Kenny Crawford who has ridden the bike at events such as the 1000 Bikes and even competed with it in a few hill climbs. Long and low, the bike barks through the twin Brooklands cans as I gingerly sling a leg over and familiarise myself with the controls. Although Kenny can use the side mounted gear lever with his leg I chose to make do using it as a conventional hand-shift. The bike lunges forward as I release the clutch and takes me up the drive and onto the lane.

DSC_5102

Kenny has told me that they have lowered the gearing  but first gear still feels as tall as the bike is long taking it easily towards 30mph before I reach down and shift into second. There is some weight to the bike of course  but it is carried so low that it is surprisingly easy to flick around as I navigate the estate towards the open lanes. Pedestrians stand, stare and gape as I thunder past clearly recognising that this is no ordinary motorcycle that shatters their suburban idyll. But once the road clears my apprehension evaporates as I realise this is it, the ride of a lifetime. I just have to open the taps and the bike drives forward, hard too. It picks up revs so fast I have to snatch into top way sooner than I expected. We’re now charging along towards a series of bends so I throttle off and let the bike slow to a sensible speed for the first corner. I’ve been warned about the front brake and wasn’t taking any chances late braking.

DSC_5103

I can see no obstacles through a short series of left-right flicks and let the bike off its leash for a few more seconds drunk on the sound, smell, speed and sheer nostalgia of the experience. I probably don’t go any faster than 60mph on this short run but the bike clearly has so much in reserve I don’t doubt GB’s performance claims for the model for a second. I take it steady doing a U-turn on a mini roundabout conscious of the length of the bike and not wanting to stall as I’d need Kenny for sure to get started again. A second run at the series of bends with more confidence this time and we’re really flying by the time I reach suburbia and the 30mph limit. As I slow I realise I can barely feel my fingers with the cold but relish the last few minutes simply posing on this monument to engineering and marketing. After all, GB not only knew how to build a fine motorcycle but understood very well what was needed to sell them too with a multitude of high-profile sporting successes and clients. It is said that Lawrence would pick up a bike from the works on a Friday and return it after the weekend with the tyre worn through to the canvas. And thanks to Archie, I can quite understand why.

Sunbeams at the TT on British Pathe newsreels

A great find by Martin Shelley with this British Pathe newsreel where “Tourist Trophy Thrills – C.J.P. Hodson, riding a Sunbeam, wins… covering 226 miles… made doubly perilous owing to rain soaked roads… in 250 minutes.” I’m sure Dodson was thrilled to have had his name spelt incorrectly!

Also from the same era we have the 1930 Senior TT when I believe my own bike took part with H.J. “Bertie” Bacon on board.

 

 

 

 

New Sunbeam CT gears arrive from Chris Odling

DSC_3115

On return from a weeks holidays in Marrakech last week I was delighted to find a box from Chris Odling containing two lovely new sets of minty-fresh CT wide case gears. These particular cogs are the close-ratio type and are suitable for many of the later Model 9 and Model 90 bikes. I needed two sets as the set in my own ’30 bike are on loan from Archie Beggs and need to be replaced. Being suitable for both the 1928 and 1930 bikes, the second set will sit on the shelf in case I have any more problems.

These gears were made to order by Chris in a small batch of different ratios and widths, so get in touch fast if you think you might be in need of a set now or in the near future as they won’t be around for long.

Marston Sunbeam Northern Run, Kirkby Stephen, Cumbria

I only just arrived in time for the Sunday run-out organised by Geoff Brazendale as part of the Marston Sunbeam Northern Run at Kirkby Stephen, Cumbria. And I do hope you enjoy the rather eloquent comment on proceedings provided by this pair of ‘beams from either side of the Scottish border.

DSC_9577

The run kicked off at 10am from the Fat Lamb at Ravenstonedale and took in 25-30 miles of the excellent local roads. Nobody in our group seemed to know where we were going and so we just found our own way round until coming across some bright spark with a map of the route. The earlier rain had long since past leaving wet roads but the autumn colours along the way were a delight.

Archie Beggs and Kenny Crawford were in fine form on the Model 9 and 90 respectively having also made the run up to the lakes that morning. And it was great to have a fine collection of flat tank models as well as a variety of the later saddle tank.

Sunbeam gears to be re-manufactured

CT gears

Always a hot topic whenever owners meet, the Sunbeam 3-speed crash box gearbox is not perhaps the bike’s crowning glory. Whilst the original Marston gears did last surprisingly well, most are now “long in the tooth” with wear causing all manner of engagement and selection issues.

Stepping up to the plate once more, the redoubtable Chris Odling is planning to produce a small batch of new gears and I, for one, will certainly be purchasing a couple of much needed sets for my own bikes.

Here follows the note received from Chris…

“I have commissioned  new gear sets for Sunbeams. These are for the narrow and wide sliding pinion gearboxes. There will be BT and CT ratios manufactured. All those interested in a set please contact me to place an order. Delivery dates will be announced shortly. It is envisaged that a deposit will be required near the point of completion and following receipt of the gear sets I will ask for the remainder and deliver them. Final cost of a gear set is not written in stone as yet, but expect around £490.00

The number of gear sets presently ordered is 20, of which a few are already allocated. This number can be increased according to interest.

After the sets have been made I envisage a few spares i.e. sliding pinions and lay shafts.”

1930 Sunbeam Model 90 factory racer lives again

I was very pleased to receive a phone call from VMCC OEC and Blackburne Marque Specialist Martin Shelley telling me that John Rooney’s Sunbeam Model 90 was up and running!

1930 Sunbeam Model 90 works race bike

There’s more information about this wonderful and possibly unique machine in an earlier post that you can view here. But since then, Chris Odling has worked his magic on the engine whilst Martin and John have worked on the rest of the bike. The guys have resisted the temptation to “restore” the bike and instead have strived to keep as much of the bike in as-found condition as possible. With original factory finish on many parts and many of the correct factory fasteners this bike could become a Rosetta Stone for the vintage Sunbeam enthusiast.

After evicting the mice and filling a few holes, even the original exhausts that are stamped with IOM ’30 S in reference to the 1930 Senior TT have been repaired and re-fitted.

There’s a short video here where you can see and hear the bike running. It does sound very different to my own 1930 Model 90 and seems to respond quicker to throttle and with less flywheel effect on the overrun.  I just can’t wait to see and hear the bike “in the metal”.

 

Update on spares in the shop

Tax disk/disc holder Tax disk/disc holder

Don’t forget to checkout the Sunbeamland shop where there are a variety of items in stock including a limited number of these vintage tax disc or license disc holders. They are replicas of an original late 1920’s Pennant item that was loaned to me some time ago and would make a great addition to any quality vintage motorcycle i.e your Brough Superior, Sunbeam, Velocette or cammy Norton.

There are also various other vintage motorcycle spares that are left over from various projects that might be useful. For example, we have quite a number of different controls and levers including items from Amal, Amac and Bowden. Decompressors, valve lifters, magneto advance/retard control.. that sort of thing. Have a look round and let me know if there is anything you might be interested in.

There’s not much left in the seat department, so grab a bargain whilst there is anything left in stock. I’ll accept sensible offers on most items just to clear the space.

 

Lucas SS49 MDB /MDB 1 Magdyno

Lucas MDB Magdyno

I have been thinking about lighting kit for the ’28 Model 90 and came across this original Lucas document on the usual auction site. The title is : Running Instructions For The Lucas “MDB” Magdyno Lighting And Ignition Set for Motor-Cycles 1929 Equipment. So, I scanned it and posted it here in case anyone else is interested.

Lucas MDB 1 MDB1 Magdyno Running Instructions 1929

I think I need a Lucas SS49 headlight or headlamp to be correct for the year, there are some very nice replicas available from Vintage Replica if I fail to turn a genuine one up at sensible money.
