    When you whack the throttle open, what does it do? Bog? Works ok but no hit?

    We (motosportz) have a 530 kit. This and porting the head would make some big gains.

    You will never have the kick of a 450mx bike with the added compression and larger flywheel on the 510's, but the 530 kit would give more power.

    Maybe look into shaving the flywheel?:excuseme: flywheels the snap killer.

    Any mods so far? Lean out the jetting just a tad, change the gearing?

    Man I have drag raced plenty of 450 MX bikes and haven't lost yet on my 09 TXC510. It's not snappy fast like my 07 Honda 450R was but it's faster. JD has a jet kit for it if you don't mind do some jetting work.

    I recently installed the JD jet kit in my 2010 TXC 450 and it made quite a difference in the throttle response plus I think I'm getter mileage as well.

    Greatly improved? If that's ture I think I will order one up. As good as it is now I can't imagine it getting any better. Thanks for the tip.

    I also got mine from Dan (MotoXotica). It improved the the power completely. Plus made it easier to kick start.

    Get a TC 250 rotor and stator and have the ignition trigger ground to be timed right.

    The rest of these suggestions aren't going to give the bike one tenth the snap this mod will. The flywheels on these bikes are way too heavy and just kill the responsiveness of the engine.

    In my opinion the txc510 works best by simply installing a 35 leak jet to tune the accelerator pump (it is too rich and can cause bog and then a burst of power when it clears, etc.). And delay the accelerator pump so that it doesn't tip into the accelerator pump too early.

    This will allow the accelerator pump to work with the full glory that god intended when you roll it on. But it won't cause an over-rich condition right off the bottom.

    p.s. I think I have spare 35 or 40 leak jet in the garage - send me a PM with your shipping address in dubai and I will send it to you. Depending on local fuel and what you need to properly jet for it - this is probably all you need to be very happy.

    Thanks for the feedback on this. From the above I think I will try the jetting option first.
    I have access to a lathe and workshop so may take the flywheel off and mod it to my own specs to lessen the rotational weight (let me know if this is a bad idea).

    Oregon rider if your up for it I might take up up on your offer :)
    The temps here this time of year are pretty hot 40oc
    Would the temperature have any impact on the type of jet I use?
