Sorry I thought we were talking about the 33's. The air jet has a big influence on off idle take off, I'm going a little larger on my 33's due to poor mileage.

Thankyou all for very useful information, my Sudco/Mikuni book seems to be the same for a lot of those specs. I may try a 117.5 main later but at this point in time I’m going to delve into the linkage recommendations as if idle screw won’t let it it come down there is a setting issue somewhere. Should the pilot used be smaller as stated by WG or have people had success with book specs?
Thanks.   David

If it helps. GD4now correctly mentioned the use of similar cross-over similar slide lifter from the 1976-77 VM26mm used on the KZ900. They are a bit more complex then needed and require a different method for syncing each slide. Also the 2-piece pot zinc pieces can get galled/bound resulting in bind and slide not fully seating. Note the spring between the 2 pieces.     One shown doesn't have the locking set screw plate but it goes under set bolt and adjust screw but only tabs up on set bolt. If someone mis-adjusted/fiddled with the set bolt this too will cause slide not to seat correctly.
