Decided to start a thread for pinstriping techniques. I'm just an amateur who's only done a couple things with simple double-lines using masking tapes, but I'll start.
The best product I worked with was Finesse Pinstriping Masking Tape, which comes in varying thicknesses, spacing, and number of stripes. I also tried a cheap pinstriping tool that had some spacing-adjustable grooved wheels that picked up paint from a small glass hopper to roll onto the painting surface. Bled all over the place with the thin gold leaf enamel. I think it might have worked with a thick paint, like latex, but that's not much help with bikes and I didn't know about it when I did my kayak, which I striped with hand-laid thin masking tape (heavy duty outdoor latex holds up decently well on a wood kayak and even the expensive stuff I used costs a fraction of the price of marine paint and it comes in any color). Hand spacing isn't bad on a consistent surface, but it would be a lot less aggravation to use the pre-spaced tape, especially on something like a bike.
