Motorcycle Repair: Fuel management, dynojet power commander, mounting bolt


Question
Who in your opinion makes the best fuel management set-up? I have a stock 07 Road Glide that I want to put a set of Rinehart true duals and a Stage I air kit on. I'm leaning towards the Vance&Hines Fuel Pak which I understand you can just plug in and go without spending the bucks at the dealer to get it re-mapped. Would this be a good way to go or what would you recommend. It seems everyone at shops and the dealer want to sell me what they stock which is understandable but quality, cost and performance is what I want. What cha think?
Thanx

OK KC, here goes.  There is no "best" fuel processing setup.  All  the big name brands are reliable.  So here is my personal opinion.  First, there is nothing wrong with a unit like a DynoJet Power Commander which acts like a total ECU.  But are you going racing?  Do you need a finely tuneable setup that you are going to change as you go from track to track and deal with different weather conditions, track temperature, and altitude?  Do you need that ability to plug in a laptop or download different mapping configurations from the DynoJet web site?  If you do, fine, it's a good unit and you can put the bike on a dyno and set it up.  But the unit plugs in series with your ECU via a 36 pin socket.  What does that tell you about its complexity and what could go wrong with it.  How about something like a Cobra fuel processor (from Drag Specialties or others) that plugs in series with your injectors and gets the results for a lot less money.  It still has plenty of adjustment for low, mid, and high rpm ranges and eliminates the backfiring and "BLAP-BLAP" exhaust noise you get when you decelerate or snap the throttle closed using something like the Harley Stage I chip.  Instructions are simple and clear.  If you are careful you don't even need to remove the gas tank, just remove the rear mounting bolt and pivot the tank up a little, and take off the air cleaner and backing plate, which you are going to do anyway.  That's how I would go.  If you use the Harley SE Hi-Flow air cleaner setup ($139.95) make sure they give you the most recent one that routes the breather tubes into the air intake (-99B) or use the Arlen Ness style, both are one-piece backing plates. Arlen's might even be cheaper.  The Rineharts are great.  Nice tone.  When you mount the left side pipe make sure you put the exact size spacer between the rear header pipe tab and the mounting bracket to the starter to just fill the gap without squeezing or spreading the tab on the pipe, otherwise the pipe will crack quickly at the tab.  The instructions explain, and they do supply a 1/8" spacer in the kit which usually works.  Do your shopping on the Web, etc.  I've seen Rineharts sell from $600 to $1200.  Air cleaner kits from $89.95 to $149.95 (all using K&N filter),  fuel processors from $200-$500.  The Cobra unit which I like because of it's simplicity (less to break or fail) and tuneability is only $239.95 from Drag.  Takes me 10 minutes to install.  Stay away from chrome billet muffler tips, they bubble and rust quickly.  I like the stock black ones myself.  Remember this is all stuff you can actually do yourself if you are mechanically minded.  Otherwise use a mechanic you trust who has done this before.  Good Luck!
