PCV question
Installed PCV, Rinehart slip-ons, and SE air cleaner from Fuel Moto a few weeks ago and was wonering if I should also have the Stage 1 download from the dealer in addition to the PCV. Is it a good idea for a backup to the PCV in addition to raiseing the rev limmiter. I sometimes have a little poping on deceleration so I pulled the plugs and the center electrode looks a little tan but the grounding tip is white, or is this normal?

Call FM about the decel pop. Simply changing the values in the 0% column either leaner or richer should fix it.
Because the Rinehart mufflers are a straight thru design with no sound insulation they can be very sensitive to decel popping. This is however very easy to take care of. I would start by checking for any slight leaks at the muffler joints and seal them if necessary. Then get the bike to operating temp and connect to the PC-V software and check the closed throttle position and make sure it reads 0% at idle. If it needs to be adjusted simply go to "calibrate throttle position" and looking at the voltage values type the "current" value into the "closed" throttle value. (Note: do not reset the throttle position, as you cannot set the openvalue on a DBW bike unless you are on a dyno and you will be calling me for the base values). If the throttle position is good I would recommend adding 10's in the 0% column of fuel maps 1 & 2 from 1750-5000 RPM's which should take care of it. If you need any assistance just give us a call, we are here to help and can walk you right thru it.

I have this exact setup and used the last suggestion from Jamie above re: adding fuel to the 0% column. I added 10s to my 0% column. That fixed all decel popping. Wanting to fine tune it, I then tried 5s. Most popping is still gone, with just an occasional issue. I'll try 7s or 8s next.
