TT1 4 Hour Endurance racing

Well yesterday (Wednesday 25th) was the third day of trying to identifying fault, since collecting bike from Focus Events depot Saturday.
Decided yesterday to temporary fit the Sachse ignition system that I had lying around. This was to try` and prove whether the Ignitech PCB trigger was faulty. Well for what ever reason the engine wouldn't run at all, sparks on all three and petrol but nothing. Decided to revert back to ignitech and substitute the Nology coils for some Bosch grey coloured coils
Of course in all this I'd had to reset the rotor, having first found TDC on 1.
When all back together , ran the engine up, expecting it to misfire, oil temp went to 92 degrees (C), the oil temp as always been a reference, the problem could easily be a time issue. Anyway highest temp seen previous had been around 72.
Today Thursday checked the wiring to the DT Deutsch and Ignitech connectors. Found the black earth wire pin (no 16 on 20 pin connector) was only being held by its copper strands, and on pulling appeared to pull out! Remade connection with new connector. Also the trigger wire for No1 appeared to be a loose , on pushing the female pin onto the male end they appeared to be loose. Replaced with a new female pin.
Whether any of this was causing the problem I can not be certain, but as changed. Thanks to Rob Bradbury for lending me a Ignitech Box to try.
 
Further update.
The earth wire from frame to battery , one of the ends was covered in green corrosion after pulling back sheathing.
Took the bike to Castle Combe 10/11th. Completed all sessions entered. Even found time to adjust suspension to improve feel.
Big thanks to Nick Alcock for the support.
Paul Ricard next stop
Tyres ready for Ricard!

Bonne chance, buona fortuna.

The number of times over the years I hear racers turn up at meets and have tiny issues that bite them in the arse they could have fixed with a plate attached and a few test rides around their block. It seems like a smart way to go about it. Way easier that seting up for a track day.

Bruno Cretti, Laverda works racer was killed testing a track Aermacchi on public roads.

A view from history:
"People blamed it on racing driver Jack Sears. Known as “Gentleman Jack”, the first British Saloon Car Champion sparked outrage in 1964 when he chose to test his Le Mans 24 Hours-bound AC Cobra Coupe on a public road.

Teammate to Jim Clark, Sears started his run at the Blue Boar services (now the Watford Gap site) on the M1, just after 4am. Properly dressed in a blazer and tie, the Norfolk farmer would have encountered little traffic as the 4.7-litre AC roared ever onwards towards sunrise.
Britain didn’t possess a circuit that could replicate the famous Mulsanne Straight at the circuit hosting the Le Mans 24 Hours, so a newly-built motorway in Hertfordshire seemed the obvious answer. His Cobra wasn’t equipped with a speedometer and only when Sears returned to the service station did his team reach for their slide rules. The car had clocked 185mph.

Unfortunately, news of the road test leaked, making front page news in the Daily Mirror. The Ministry of Transport ordered an inquiry and 18 months later, on December 22 1965, a 70mph “temporary” limit was imposed on all unregulated roads for the first time.
The new rule effectively created a national speed limit, which was extended four months later by the newly-installed Minister of Transport, Barbara Castle (who couldn’t drive). Two years later, 70mph became law, while the national speed limit on single carriageways was lowered to 60mph in 1974.
Castle had called for a profound change in public attitude to road safety, but what were the factors at play and was Sears really responsible?"
 
Obviously, I wasn't talking about maxing a race car or bike out around your housing estate. But managing a few laps without flattening a battery or running on half the cylinders, or even just starting it. Be good to know it starts and makes power, gets all gears, brakes work, wheels go around, and dont wobble or fall off. I remember years back a 1000k trip to Philip Island resulted in a full rewire in the pits just to start that bike, before 1 track lap was done, better to do that in your own shed and riding it before that 1000k trip would have found that problem.

Totally with you on that philosophy. Not possible in many cases, but sure does iron out many bugs and give you confidence at the same time.

Many a speedway bike was ‘run in’ on a trailer on route to a race meeting after a rebuild. A trimmed down clothes peg between the cable and carby top kept it at high revs and no drive chain…. simples.
