I'm not there yet, too many other projects in line, _but_:
Recent gas price spikes make it interesting to consider getting one of my basket case Triumphs left over from a previous life, back on the road. Of course the type of gas we got back in the late 60's early 70's is no longer available except at the airport, and if economy is a big part of the factor, it would be nice to run cheap swill anyway.
So, besides lowering the compression ratio to, what, 8.5? 8.0? does anyone have experience with a _successful_ dual plug set up on 9 stud T120 heads? Is the improvement in antiknock worth the effort? What about head cracking between the plugs? Did you use a pair of Honda dual coils, or? Did you stagger the timing? How? (I used to run single Honda dual coils as the main coils on some of these, the extra spark supposedly helped scavenge on the exhausting cylinder. Mainly at the time they were more available, cheaper, & more reliable. )
Thanks!
