I live at close to sea level, running a Pro Moto exhaust insert, throttle screw trimmed, WR timing, grey wire not disconnected JD Blue Needle in 3rd position and 168 main jet.Pilot about 2 turns. With the exception of very slight popping on decel it runs very good and the plug shows a nice tan color. Temps have been moderate (50 to 80 f) In a few weeks I'm hauling her to Eureka Nevada and riding between 5000-7000 feet in elevation. I dont expect temps to rise above 90 deg. F. What changes should I make as a starting point? Also I noticed a lot of TT'ers are using Zip Ty or other pilot screws, what is the advantage to these aftermarket screws?
