Thanks a lot for the information Albert. As usual you are the only one to give a positive answer to my ideas, all the rest are always don't do this or that, why bother etc. There is always room for improvement, especially on BMs.
I have always found ways to improve on a certain designed machine which is lacking in the modern ways, as is the way with my 1973 TRIUMPH DAYTONA 500: spin-on oil filter, electronic ign with a Honda cbr dual output coil, high output alternator with a Suzuki reg/rectifier, American bd valves and guides,racing type front fork internals and I have to tell you it holds 6.2 pints of oil. A lot more than the g/s, and by the way she has covered more than 200,000 miles with out a break down and that includes many trips around Europe.
Anyway I will proceed with my origional plan and install the oil tank, probably on the top rail of the engine crash bars,
again best regards Albert and safe riding to all the negetive heads, Mike.
