A couple of questions...

Do you run twin throttle cables. I.E. a pull push cable te each carb, or is a single cable to each carb OK?

anyone like to share what jets/needles/setting you use on a 900 engine?

I run a single cable for me but regulation push/pull for customers. ;D

Twin here, sticking full throttle is nasty...

Solo cable requires the return cable to be cut off at the throttle to leave the plastic locating spacer guide thingo to keep the pull cable in place or else it will jam. IME the solo cable done correctly runs smoother, returns better and gives better feedback than the push pull set up. You have to sacrifice the return cable to use the plastic locator to do it safely and correctly.  For liability reasons I leave it stock for customers. You could probably fab up a spacer to do the job but I cut the return off for the opposite locator to hold the pull throttle in position. I'm running a custom Powerbarn 2 into 1 throttle cable set up for my split FCRs.

It has been suggested to me to run a 2 x single cable set up like Dellortos, but I haven't tried it. Read that it works better than a 2 into 1.

The different calibration of oem jets and copies can throw your tuning off. The local importers of both Keihin and Mikuni have cautioned me regarding a flood of unreliable copies.
