Good morning. I know there is a lot of information on Mikuni Carbs out there and thought I had a handle on it until I got as information from OSD when looking for parts or new carbs
I know the carbs have been rebuilt before and Nick stated they a special series made for the 657x with discontinued needle jet springs which he thinks are 115 grams.
What I have found looks like the spring should be 80 grams for dual carbs and 95 for the single carb.
Is the correct for the BN38 (I) pictured in this post? The springs that came with the rebuild kit from SBT pop at different PSIs and I believe they should be the same PSI.
Any help would be greatly appreciated. Cheers, George
