to re-jet the honda the JD Jetting kit comes with five mains and two needles , the chart shows the altitudes and what works best ( most of you already know this stuff , but for those not familiar with the honda ) removing seat and gas tank to get to top of carb is easy enough. its all the hose that are in the way that slows it down . and if you notice in photo the sub frame is all jacked uo in the air , honda said to do that. put in the new needle from JD , red dot warm temp , this is Texas . then it was time for the mains . I chose to install the 162 main jet , it is rated for a higher elevation than central Texas, more for the Moab trip in the future. as the stock needle was a 145 the 162 seems to work just fine , for now. I might re-jet with the recommended jet ,165 at some point , or could do the 170 main they sent ( and with airbox mods , JD says it will run more like the 450R . more than I need I think ) could not have finished this today in my driveway as I have no garage or shop . so Carrot got the job done , I think we both learned something today ( EFI ) is great . this carb thing will work , it has for 100 + years .
