Hi has anyone fitted a Tri Spark electronic ignition system to a 1975 Trident T160.
Yes.
Could you let me know what difference it has made and whether you think it is worth changing from Boyer Bransden.
I would expect you to notice an improvement over the Boyer system-especially when starting using the electric starter.
Triple owners who have fitted Tri-Sparks in place of points or other electronic systems are usually full of praise for the Tri-Spark (myself included) and how the Tri-Spark made a noticable improvement to the general running of their triples.
If you are a triple owner (presumably you are) then I suggest you join Triples Online
