I had purchased a rebuild kit from Z-1 for my 71 CB450. In the kit the jets were different sizes but I really only needed the gaskets that were included. I do however need to use the float valve set. The one I took out that I never had problems other than a little leaking was a 2.5 and the floats are supposed to be set at 20mm. The ones they sent were 2.0. My question is can I use these without issue and if so do I need to adjust the float level to compensate for the different size. Thanks.
