Whilst at the Stafford show, on October 21st, 2007, I spotted an alternator B31. The price seemed fair, and the bike just looked about right. No problem to add lights and such like, so I promptly bought it.
A set of lights later - which in turn warranted a new alternator, and the "30 bobber" as it had been christened was all set to hit the road.
Just the sort of machine for playing in the snow - and playing in the sunshine. All in all, a pleasing little bike which is great fun to ride.
Ok, so there was a little issue with the bike smoking when leaning on the side stand, but I can live with that. Here we are down by the river, October 2009. If only the bike and myself knew what was about to happen . . . . . .
This is the 30 bobber as of March 2010. As you can see it appears a little damaged. The damaged to the bike was nothing compared to the damage to myself. I now have enough Titanium in my pelvis to build a bike frame - I have a skin graft from my thigh to my shin, and my left foot doesn't work as it should. I still can't walk, or sit upright. All this because some car driver didn't look before making a turn. Be careful out there, they really are out to get you.
I'll update this page as both the bike and myself get fixed . . . my money is on the bike getting better first.
Right, here we are, the beginning of March, 2012 and I've started getting the bits together for repairing the 30 bobber. The main cost was the petrol tank. Despite searching high and low I've been unable to find a two gallon "Catalina" tank with pear shaped badges. I've had to go for the "Gold Star" tank with four inch circular badges. I've decided to buy a toolbox for the left hand side, so that it matches the oil tank on the right. I've got most of the bits for the front forks - the one stanchion was slightly bent. The only other component which was destroyed was the headlight - luckily that was something I already had in the garage. The other damaged parts - mudguards, shocks and seat can be replaced as I go along. So far, it's looking like the bike will be up and running before I am.
Almost three years to the day . . . and like I said, the bike is now better than it was before the accident . . .whereas I ain't. As you can see, the colour has changed and the bike has grown a set of indicators. I didn't bother with renewing the mudguards - the money saved on those went towards the indicators and the cost of the powder coating.
I think this is the bike that had the most use this year. Although it ain't exactly the fastest thing in the world, it rolls along nicely. The performance was decidedly down earlier in the year, in fact the bike would not exceed 52 mph no matter where the throttle was. Try to go any quicker and a rather nasty noise appeared somewhere in the region of the cylinder head.
As you can see above, one of the exhaust valve springs had decided to break. Luckily the smaller spring held and the valve didn't drop into the cylinder. Nothing that a few quid didn't fix.
Due to me getting my new hip fitted in January, the B31 wasn't started for three months - when I did fire it up ( first kick, as it always does ) the ensuing smoke screen was causing birds to fall dead from the skies - well almost. Now seeing as my B33 is fitted with one of these wonderful anti wet sumping valves, I thought I'd spend a few quid and fit one to the B31. Now it doesn't matter how long I leave the bike standing for it does not fill the crankcase with engine oil. . . . .and that's really just about all I've done to this bike apart from put petrol in it and ride it.
The B31 has been out and about quite a bit this year. It tends to be the bike I use when I ain't in any particular hurry. All in all, I do enjoy riding this machine.
Here we are outside the Butler-Henderson cafe at the Great Central Railway
Now whilst returning from a run over Leicestershire way, I noticed the B31 was making a slight knocking noise. I didn't think it was anything too dramatic - at the worst I reckoned it was the small end bush worn. Oh dear - how wrong was I ? I pulled the top end off the engine only to find the big end assembly had gone. Like the D14/4S rebuild, the repair work on the B31 has had to be put to one side awaiting the funds to complete the job. . . . just another one of the many ways this injury has prevented me living life the way I would like to.
The B31 bottom end was rebuilt with the roller assembly from a Yamaha 660 single - the barrel was bored out to take a Triumph Bonneville piston. The knobbly tyres have been replaced with a pair of Dunlop road tyres . . .and the B31 is now rolling along as happily as it has ever done.
Well the B31 has just been getting on with what it does best - rolling along at a steady pace and taking in the scenery. Reliability-wise, I've had no problems at all, which is fine by me.
The B31 had a bit of a problem with the swing arm spindle moving in the frame - then to add insult to injury, it also snapped the chain . . . and before all this, the battery went toes up. All this was soon sorted out, and the bike is now all happy once more.
