So I just got done with the first ride on the 04 firebolt the other day and today I get home and go to start it and it wont. It turns over and I hear the fuel pump kick on but nothing. Im going to check the plugs tomorrow but damn...Ive had the bike less than a week. What would cause this? (if this is even the problem) Bikes only got 7000miles.

if u bought it used, chances are it sat on the showroom floor/garage/shelf for a few months or so.
ur battery is low probably. i would charge it, run all the gas out. fill it up. put about 50 miles on it, and put some wood/plastic under the kick-stand at night. and have the plugs cleaned. |

NGK -DCPR9EIX Iridium First time in my life I have ever changed plugs in anything (motorcycle, car, truck, boat, etc.) and had an extremely noticeable difference (other than changing out fouled plugs of course)

That would be the problem; the plugs are fouled. a wise man once told me "Buells are not built/designed to start up sound cool & look cool, they are built for one thing: RIDING!" don't ever start your Buell unless you are gonna ride it. this will help the life of your plugs tremendously

best bet would be to go with the NGK Iridiums, you will not regret it
don't think I would want to start a cold motor at WOT to clean it out. Put the new plugs in it, take it for a ride, once it gets warm then blast it out make sure you get the 9's (DCPR9EIX) the 9 is the correct heat range plug for our bikes.

| so is it very challenging to remove the plugs or is it just a removal of air box and air box cover | |

| its not very bad at all; just make sure that you have a 3/8" drive extension and swivel (for the rear cylinder). should take about 15 to 20 min. total, at the most. | |
