Obviously this isn't a CB but it's under 550cc.
Does anyone know what ratio I should use?
I've tried a trail Tech electronic tacho but it's like a random number generator. I have since heard from a few people that for some reason ( maybe to do with the magneto) that these bikes generate a lot of noise that confuses electronic tachos.

Granted they are not in the best shape but with a little paint they will look good... If you don't like em patience is your friend. These bike are old and sometime take a while a for part to show up. I waited 6 months from my box wire case for my XL500R before one came up.Good luck...
