On the carbs, I did find that some of the carb parts that are superseded on the CMSNL site weren't correct. Also the are some JDM replacements for balance / tickover wheels are good. Phil installed some pattern jet kits which seemed good to get the carbs in a good state, ready for a dyno setup. We're waiting for GT to confirm when their dyno is back online.
