    Low throttle snatch

    Hi
    I own a 2020 cross runner and find the throttle snatching at low speed have been advised to go for a power commander but they are not made for this model year so my question is how can I smooth throttle response. Thanks.

    Fairly typical VFR fuelling I'm afraid. My '08 VTEC suffered the same. I managed to cure most of it though with a combination of the following:

    O2 eliminators
    PAIR delete
    snorkel removal
    flapper valve disconnection
    regular SV balancing

    Sadly, the SV's on the later model Crossies are hard-wired. The manual says they are factory set then not to be touched - used to be a regular thing on all my VFR800s.  :155:

    Assuming proper maintenance, I'm not sure how much a PC, RapidBike tuning module or even an ECU hack will do but may be worth considering if it is bad.

    Best of luck.

    So called throttle snatch on later models is from ecu module recalibrating from hard high speed riding to street traffic I think you will find. My 16 does it from highway then hitting small towns. Nature of the beast & I like it.

    What about the Booster Plug? I don't use one as I have no problem with my 2019 CR but I've heard they're pretty good.

    Apparently it enriches the fuel ratio at lower revs to eliminate the extremely lean mixture problems caused by adherence to the Euro 4+ regulations.
    There are numerous web page reports on the product as well as You Tube videos.

    The results will be interesting. It seems, unlike on most bikes, it is not a straightforward job fitting the plug to the CR because of the location of the AIT sensor.

    I had my Gsxs remapped, bit expensive but ironed out all the euro4/5 running bugs and gave a couple of horsepower too, it was incredibly smooth.
