carb identification

[gandolf]

Hi,

Found a carb set that looks really clean. Owner said they were from early 90s but didn't know exactly what year.

How do I find out what CFM these are so I can check jetting? Are there any markings anywhere that indicate?

Thanks

not that I know of. the 454 has chrome tops [but could have been changed] the others have plastic tops [EX/ER 500] you would have to remove the float bows to look at the jets depending on what they are would ascertain which bike they came from and therefore the CFM rate. a picture of the set may help as there are differences to the design of certain fittings. I think.
