BMW Airhead revcounter?

[Voltaire]

Looking for a mechanical tacho for my classsic BMW racer project.The ratio is 2:1, wondering if any other tachos of other bkes are similar?
I think Brit bikes are 4:1.....Japanese??? A big Honda one from a 750/4 would look good.

wazza matter with the stock one?, gut it out of the panel and use a polished spaghetti can (must be Watties) as a surround

I like these myself http://www.srmclassicbikes.com/new-products

edit: quick look and it seems some Harley Ferguson run a 2-1

Wow thats cheap, thanks for the link....bet they only ship " upper 48 Alaska and Hawaii...."

The bike was never a bike....engine on TM, rolling chassis swap meet, other bits off Maxheadroom and Ebay.
