    A short video of the TE449 in the real world showing no flameouts, bogging or hanging throttle.

    Riding the type of terrain in this video, going from idle to cracked throttle and back to idle again, will quickly bring about flameout from the standard set-up & the hanging throttle of the faulty second butterfly system will throw you into the trees.
    Having the second butterfly out adds the quick response needed to pop the front up over ruts & roots etc & takes away that 250cc feeling.
    The power is still very easy to control using the supplied power adjusted on the RH handlebar
    (I.e. The throttle):D

    There are other ways of achieving this, but for me, this wins hands down on price alone.

    hey dangermouse - I am considering this mod. I too have had issue with the lack of quick response needed to pop the front wheel up on this TE449 bike. I get the flame outs here and there but otherwise love the bike. These days I'm more into sight seeing and technical skill development than going like hell through the woods at break neck speeds. I've heard of the mod and briefly rode with a guy who did it. I'll be searching for more info, but if possible, could you point me in the right direction with regard to instruction and or info? Thanks.

    Motosportz - i'm educating myself on the topic...just started. I don't even know exactly what ibeats is although I have an idea. Is there a quick, clean post with directions on how to best do this mod?

    I was talking to DM449 and his most excellent mod. :)

    Lots of threads here about it, use the search function and read on. The removal itself is simple. Some tuning might be required after but my bike simply ran better, better response and no dead throttle which is much safer.
