Re: CB550 Cafe
Yeap. . A gentleman in Cal. (Found him on Ebay) takes your core carbs. goes though a complete tear down, cleaned, blasted and baked them to whatever color you want (My customer wanted all black & polished). then re-plate all steel parts zinc, and polished the alum parts, Installed all new internals, Told him the bike setup 4-1 exhaust running open intake velocity, set it up on running bike and syn'ed all four carbs with the correct main and pilot jets then sent them my way - Very pleased !!.
His name is Bob, his ebay ID is "kpruyne",
Couldn't have done it myself any cheaper. . gave me time to work on other things that needed my attention
