#1 - Do ALL US SV's have the 2-3 gear ignition retard? I have seen the notes about cutting the red+yellow and the brn+blue wires under the tank, but before I cut, I want to be sure there is some benefit.
#2 - I've seen articles on a 4-degree ignition advancer (offset key). Has anyone done any dyno testing on this mod? How beneficial is it? What is the down side? Will I need to run premium then to prevent early detonation?
#3 - Any suggestion on the best way to remove the undertank foam? I want the end result to be as clean as possible.
OK #4 - I plan to stick with the stock 15 pilot jet, and go 3 turns out on the air screw, than shim the stock needles with 2 shims, install a 140 main, and drill the slides. If I remove the undertank foam, put in tank spacers, and put on a good slip-on, is going to a 140 main jet enough? I'd rather run a little lean and get good gas mileage than go too fat, but I don't have easy access to a dyno to make a dozen runs to dial in, so what is the groups experience???
