I've run on E10 apart from a few 'test' fill ups with E5 since it first came in. Can't say that I've noticed any real performance difference apart from a slight reduction in fuel consumption (less than 10%) which is what you would expect. Also no issues with degradation of plastics so far. I do wond...

This has been pretty well covered by gspd but I can't resist the invitation to elaborate... :roll: The coil of the solenoid has a very low electrical resistance... it has to have so it can carry enough current to pull in the solenoid. This means that if you put a bulb in series with a twelve volt ba...

They (diodes) aren't rated in watts and you can't infer a wattage by multiplying amps by volts since the two ratings refer to different conditions. That's why I asked what specific diode you (Rob) would recommend for this application. The few times I've needed diodes for a project, I would simply e...

Rectifier Diodes are rated are rated by voltage and current. The voltage is the reverse voltage that the diode will take before it fails i.e. the blocking voltage), the current is the maximum current the diode will carry in the forward direction. They aren't rated in watts and you can't infer a watt...

Was the relay specifcally sold as suitable for a BMW Rxx/6 model? The flasher circuit is unusual and different to that on most contemporary vehicles including late (post 80) models of the airhead. I'm wondering (based on the packaging) whether this relay is intended for use on a vehicle with a trail...

Not knowing the details of your points booster, I can't really comment but, if it's essentially substituting a semiconductor switch for the points (no matter how triggered)... as you say, the energy dissipated in the igniton system is dependant on the coils rather than the switching method so your ...

There's no getting away from the fact that shorting will increase the HT current many times and while I've used the shorting method on my points booster electronic ignition without any adverse effects it does retain the original points coils which limits the energy being dissipated. Not knowing the...

I would certainly not short the plug leads on electronic ignition although I've done it on points ignition including with my kit built ignition amplifier in place after noting that there are several blocking diodes in the electronic circuit to protect against a back emf and there is a condenser to ...

I would be very reluctant to use plug shorting on any electronic ignition. With the plug lead shorted, there is a very intense and much higher current through the plug lead. This in turn means that the current in the primary of the coil will be higher and that the reverse EMF thorugh the coil could ...

But in any case the they are not the same cam as a type 247 equivalent because the shorter stroke of the type 248 changes the angle of the pushrods which changes the timing. Absolutely right. The effect of changing the angle between the pushrod and the camshaft will move the timing for one 'engine'...
