    It sounds like lot's of us have been installing Air kits and either slip ons or new pipes from various manufacturers. There is definately a wealth of knowlege on these boards when it comes to upgrades and mods and that's awsome!

    I just installed my thunder air kit and Cobra FMS this afternoon, I had just recently done the exhaust mod. I have my FMS set at 2-2-2 as this is what more than a few folks have said is the optimal setting. I haven't had a chance to ride yet as it started to storm just as I was getting things wrapped up so can't comment on the ride. My question is if this is still the best FMS setting with this configuration? I do plan on upgrading to either the slip on or the full exhaust as some point so I know it will change again after that but in the mean time it's a pretty good mod and I don't have enough experience with bike to know what to listen for.

    Many thanks if advance for any help you can give.

    Its not so much what to listen for, its more about what you feel. If the bike pulls hard through the entire RPM range than things are good. If power drops off after 5th gear at wide open throttle than if you want adjust the third pot it will give you more top end speed. Just read the directions and you will under stand. It is alot easier than you think.

    Thanks, sounds like I really just need to ride her and figure it out as I go. Another question. Are the three led's supposed to light up when you turn the key to on or not until after you actually engage the starter? Mine didn't light till I started the bike but did act just like the directions stated with the green led staying lit.

    On the instructions it says when you turn the key on the lights will come on for a few seconds, and go off.

    If this does not happen check to make sure the side stand is up, the bike is in neutral, and the clutch is in and the handle bar switch is set to run.

    If there are still no lights recheck all connections, and make sure your ground is connected correctly.

    2,2,2 should work out good for ya with your current set up. You may have to adjust more for your personal feel. 2,2,2 from what i found has been the best balance between milage and set up. Ride it and get a feel for it. Another thing you can do if when ya ride leave the controller hanging out so you can see it, you will see different pots light up and you do different things under different loads. This will also help ya fine tune to your specific set-up, riding style.

    Thanks for the confirmation, if it ever stops raining here I'm gonna get some miles on her and see how she feels.

    This site is great with loads of knowledgable folks always ready to help, glad I found it.

    I just got back from my first ride with the FMS and New air box. These are my observations:

    • No more popping on decel
    • An overall more powerful feeling throughout the powerband
    • Accelleration is more responsive
    • Less heat on right thigh but now I feel it on the left side
    The bike feels good and performance is better, I think 2-2-2 is a great starting point and I'll have to ride her a few more times before I consider fine tuning.

    Has anyone else noticed the heat issue? I swear I felt no more heat on my right side but now my left thigh is feeling it all. Do you think this could be the Airbox deflecting the heat (downward teardrop design) or could it be an FMS setting?
