I have heard (and believe) that as well and that was the direction I was trying to head. The easier / harder part was in actual procurement. I could not find an outlet where I could talk with someone and discuss what calibration parts I wanted shipped with the carbs. Nor was it clear to me which carbs had which, if any, style of pump. Some of the sources that have people working for them can only get the ND but not the NS. I guess they sell mostly to KTMers. I did not want to buy them knowing that I was going to throw away $50 worth of parts in each carb on the day the box arrived. I specifically wanted 38mm instead of 40mm because I like lower RPM performance. Screaming the guts out of an airhead motor is not my brand of fun.

So, Bill at Rocky Point made it easy for me to order the R90S spec carbs with starting calibration that should run long enough to get me into tuning mode. This is going in a new crank-out motor build with Enduralast and EnduraSpark and I wanted a fighting chance to get the machine to light and run long enough to do the initial break-in without the carburetors being totally out of range.

I have enough challenges in this project already, I was never the smartest in my age group.

Rubber mounted should help with reducing heat and vibration to the carbs, mine seem to stay in tune for a reasonable period. Won't work with Pod filters as the carbs will probably fall off too easily.

I have rubber mounted PHM's and I needed to change the spigots. It might matter what model you are starting with? I don't run pods for a number of reasons.

Last I checked, Herdan's could have set you up just as you wished. Rubber mounted PHM's with stock R90S jetting. For less money too!

Story of my life (so far). I appreciate the understanding I have received from this thread.
