California professional and backyard builders have now a new reliable and reasonably priced motor option to make their custom ride C.A.R.B. compliant. Ultima just informed me that their carbureted engines can be sold in the State Of California without you risking big fines… and worse. But I have to mention and underscore that in California the use of any after-market engines is for “New Custom Built Motorcycles”, NOT for pre-existing already registered motorcycles. Ultima engines can be purchased in natural, black or polished finish & in their most popular displacements ranging from 100ci to 127ci.
All the certification paperwork has been done for the homebuilder & small volume manufacturers in California. But I also remind you that for any brand of after-market engines the law states specific requirements outlined in the Ultima C.A.R.B. Engine manual, including (but not limited) to hose & carbon canister routing, fuel tank location & capacity, gearing & exhaust back pressure that need to be adhered to during installation. Upon purchase you will also be required to fill out, sign & return an agreement concerning your warranty rights, installation obligations & scheduled maintenance before you can receive your M.S.O. or Compliance label. With your purchase Ultima provides C.A.R.B. Engine Manuals (also available in the company website as a downloadable PDF File). Ultima Products.
