    hello ladies and gentle men, hope all is well in camp exup.

    i was just wondering have you guys tuned yous fizzers at all and what kind of mods you've tried. i dont have mine yet but when i get it (5 days encounting) il be looking to personalise it a bit and maybe increase performance if possible. im getting braided brake hoses fitted which increases braking performance.

    also if you've done any mods or tuning that DIDNT work id be very interested as i dont want to fcuk up my new machine!!

    thanks boys

    I've never done any on my previous bike. I'll be interested to learn what you have / are planning on doing!

    Haven't done any mods, but my Brother-in-law has given
    me Carb's that have had the idle jets drilled out,suppose to make
    the fzr run leaner just above idle he says, as they tend to
    run rich.

    When I asked Hubby to fit them for me he said,
    "Its going good and does't need them.. yet".

    gday

    just not sure if i was even going to get the fizzer back on the road (done a head gasket)

    i had planned- 4 X air filter pods, new end can (probably whole new exhaust so i dont have to remove it ti change oil- does mean i'll lose exup for torque but gain a few more ponies up top) port & polish head

    i have a 2kr with 3ln motor and 3ln carbs on it (carbs are heaps bigger with bigger jets as std). i was going to dyno it- a must with exhaust and air pod upgrade. too lean otherwise. maybe lay with sprockets to rev higher if i lose exup. sticky tyres. that should get it moving a bit better.

    If you do get it dyno'd, please send me the pics and graphs. I have several folks over on the Brotherhood that would LOVE to see some numbers from a 250. Please?
