Can I please get some suggestions and contact info for a person/shop experienced in Zenith-Stromberg race preparation and tuning?
Dying in left hand corners. :(
I understand this is not a new or unusual problem.
Thank you,

Where are you located?
I did this a year or two ago for a Triumph.
There are online CAD tools and instant online-quote, quick-turn prototype machine shops that are part of the solution.
Do you have the attachment drawing for the front end of the Rocket?
