hi i am new to this site and have a few questions regarding my newest trike, 85 tecate 3. the stock carb looks nothing like the one thats on it., it has some stupid flat side on it and the bike simply just wont run right. well my question is will my stock 86 tri Z carburetor work? what is the major difference in mikuni carbs for the old 250's? or if anyone simply has a decent tecate three carb i can buy off them that would be wonderful. thanks guys
