    hello everyone! just wanted to know everyones opinion on getting a dyno done. my 2006 fxdli low rider has had all the work done.(vance/hines big radius, power commander, arlen ness big sucker II and a monster baffle installed.) my question is, (and i hope its not asked too many times!) do i need to get a dyno, or should i wait-take it for a ride and see how it goes from there. its still in storage cuz the snow is still flying outside! i just have know idea what to do. the dealer said to wait and see how it runs first before getting it done. any thoughts or comments?? thanks a lot!! bill

    I'd take a ride first. If the power commander was set for your changes you may need only minor adjustments. If putting it on a dyno will put your mind at ease and you don't mind paying to have it done go for it. Just my opinion.

    There is a difference in getting your bike dyno'd and having your bike dyno tuned.


    If it were me, at a minimum I would get the bike dyno'd and make sure that the operator uses the AFR probe to give you a run with both HP and TQ and AFR so you can see if it's really lean.

    I would imagine a good operator will tell you they can improve your power and fuel mileage etc which they probably can.

    Be sure your rear tire is inflated properly, also just watch and see if they check the rear tire pressure, it's a sign of a good operator, some might forget but they should always check pressure.

    After doing this you can determine if you want to tune it, and if it needs it, and then what software or device you wish to use to tune

    SERT
    PCIIIusb

    two of the most popular.

    If the $$ isn't a problem, I'd dyno it. Runs usually are around $70, though that can vary wildly. Even if you only do a straight check run, you'll get a lot of good info that can help you down the road.

    Dyno tuning is real good,too - just make sure you dyno it at roughly the same altitude as your primary riding; i.e., if you live in Denver or Sante Fe you don't want to dyno tune it when your in Galveston or Daytona.

    :cheers:

    i'd go this route first. with the way the weather is it's hard to tell whats up with it till you you get the oportiunity to really run it, at it's normal operating temp. sounds like you're on the right tract, you just need the time and weather to experiment a little. Have fun:devil:
