Re: 700 polaris lean condition mid range
I have a '99 700 RMK w/the works (case porting, cylinder porting, SLP pipes, Union Bay head, reeds, bored carbs, etc).
I ran into the same problem you have when I installed my boost bottle. I went from 42 pilot jets to 48s (alt compensator REMOVED).
I am assuming you removed the alt compensator when you starting mod'ing the motor. If you haven't, yank it, it's causing part
of your problem. Once you have removed the ACCS and capped off the ports, install size 42 pilot jets and put the clip in #2 position.
If you're running a boost bottle, you should probably be running about a 48 or 50 pilot jet. If bigger pilot jets don't solve your problem,
you're probably sucking air from somewhere around the carbs. My carbs have been bored to 41mm (which doesn't affect setup as much
as one would think) and I run a size 48 pilot jet, clips in #4 (rich), air screw 1 1/2 turns, and 175/178 mains which runs at 1300 degrees
WOT at 7800 feet. Hope this helps, keihen carbs and porting work awesome together, but they can be real bitch to get dialed in
