    lol, a Shady Shrader product.

    Good luck.

    Don't use the tune.

    That's a 3.709" bore. Seems silly to go through the effort of case boring for a non-standard size bore and custom piston. Probably 1250 with a typo.

    I agree. I bet it was a typo.

    Well he told it to me in person so no typo. Just B.S. I figured.

    Especially with no papers. I'd have to say someone who went to that much trouble would most definitely have a record of that much work and it would stay with the bike because resale.

    My AFV is 105.6% without the new tune. It feels okay, there's a little "lumpiness" in the power curve. Basically, it kicks in hard at around 3500 and pulls really well up to around 6500. Then you can feel it drop off from there. I just shift. Off-idle torque is fairly good. I love the way this thing sounds - so tight.

    I'm just curious what his response to my AFV will be - he thought that with the stock pipe 105% was "a bit too high and would indicate a mechanical issue".

    Anyone else have any experience with this? 105.6% with a new pipe seems fine to me.

    - The intake is not leaking - tested that out.
    - It has the airbox "delete mod" that just has the K&N filter under the airbox lid (tank lid).
    - New plugs & wires
    - Exhaust is tight - especially new one. (That mount bothers me but I think I can make that work).


    Other than a tune, what am I missing?

    Others may chime in with much more detailed info, but 105.6 is not extreme to me at all. If you start getting to 110-115 I would be more concerned, especially if you thought you were on the right tune. You opened up the flow of air, and are now running a little lean. I don't know what that pipe does to the powerband, but my XB12 wakes up at 3k and dies off around 6. Does it feel hotter than normal? Did you go from stock pipe to this one? if so I'm surprised you're actually that close on the tune considering both the intake and exhaust are now more free flowing. Get the tune, reset TPS, and go scare some pedestrians.

    Good. You should shift. Redline is 7k.

    Like Ride the Lightning said: 105% is well within a decent tune and the ECM is adjusting easily. If you like the way it runs, I'd leave it alone.

    'Lumpiness in the power curve'. Somethings amiss.

    Maybe, but I ignore all 'butt-dyno' claims. If it's that bad, go to a dyno and see. On paper.

    Yeah it's not that bad - it's just butt-dyno. It's just an observation and not something I'm concerned with. Again, I don't have the new tune from Rev-Mo yet. Things could change with it.
