how do you know when primary is full and what oil do you use

I bought a pair of the Samson Rip Saw pipes for my 2002 FXSTBI from the Big Gun series a long time ago. I also went with the SE air cleaner and had the dealer install the Stage 1 download. I noticed a dramatic decrease in the low end and mid range since putting the pipes on and finally want to correct it. I have also noticed the rear cylinder is running lean (excessive bluing on the rear pipe only) but have heard little "lean pop". I have a few questions. Will I benefit from installing the Dyno Power Commander and mapping it myself to correct these issues (even being inexperienced with mapping, i.e. is it user friendly for someone who has been tinkering with carbs for 10 years)? To correct the loss in the low and mid range, will the performance rings help or would the shortie baffles or...

Hey all, Need a silly question answered. Gonna put apes on my Duece (03') and I'm wondering how long of cables to get and where to measure from and to. Single front disc. Stock CV Carb. Thanks Skully

Rev Tech 100 engine, just over 3500 miles I pulled the plugs to give a look. The spec sheet says the gap shoould be .040" but the plugs were set at .025". It just seems that the .040 is way too large, but I don't see any any difference in performance except at ilde where I get a few more "pops" then usual. Any thoughts?
