Hi Tommy,
Shouldn't it be 35:9 for a solo bike?

Re: Long Engine Warm Up ‘55-‘69

Yes move the slide needle down to #3 position one hole up from the bottom hole and check that the idle jet is correct size
Note: Like any engine it is not a good to start and drive without some warmup

Re: '63 r60 losing power after warmed up

Yes the spark will take the shortest path to ground
I always insert or trim the plug wire not to exceed the bottom of the coil terminal
So the picture I posted with the coil wire inserted past the bottom of the coil terminal would make the gap less than 10mm

Any sparking at the safety gap is not good and would certainly get worse under load and at a higher rpm It is usually caused by a bad plug wire or plug cap which you said have already been replaced? check that the gap is at least 10mm and the the plug wire on the coil is not to long coming out of t...

Re: Where to locate all the rubber parts of the headlight support brackets?

If the hole is clear of any burs then it looks like your replacement part outside diameter is too large
Salis site has dimensions listed and states you should be able to make them from some rubber hose or stock
