unrestricting a zxr250

[fadz90]

Hey all, just want to know if there are any quick and cheaper ways to give my bike abit of a boost.

A mate of myn said to get k&n airfitlers and thats does it a lil kick, but yea besides throwing any serious cahs on my machine, any cheaper not cheap! solutions would be useful to know.

cheers all!

Cheap stuff
Slip on
jet kit
air filter

Expensive stuff
Full system
head work
cams

Other to consider
Lighter chain and sprockets
ignition advancer
bigger air box
Reducing weight

As, or more, important
Suspension / handling
Brakes
Rider ability

I'd suggest the best way to get more performance from your 250 is to fine-tune the nut between the seat and the handlebar. Learning to ride will make much more difference to the real-world performance than even doubling the horsepower of your 250.

Changing the air filter will (may .. see note about K&N filters) allow you to draw more air, meaning you can burn more fuel whilst maintaining a stoichiometric ratio. If you changed to a high-flow filter and changed the jetting to flow more fuel, and then added a free-flowing exhaust to get all the burnt gasses out you may well a performance boost of about 6 horsepower; this will probably cost you a grand or so in hardware and another $400 in dyno-tuning expenses. Add another couple of hundred if you need the mechanic to fit them for you too.

Regarding the K&N filter, it is generally accepted that these filters don't flow any additional air, but being cleanable/reusable they provide better value for money. For a true high-flow filter think about a BMC race filter.

Why don't you think about investing $400 in a Superbike School instead.

Save your money Fadz, learn to ride the bike and when you do get you fulls licence buy a 600 that will have more power.

Your not gonna get that much more power for the money your paying for the mods and you will not get that back on re-sale mate trust me

Nothing to Nanna here, tis all been done. Better then I could as well.

Just to add, reduce mechanical losses ie. friction where ever possible.

how to make a 250 go quicker...

1. get on the throttle

2. just lean the kharnt...

these both take time but are fun when u can get the hang of it

What he said.
And add to that going on a diet doesn't matter how much you weigh now, every bit helps
Although I didn't do too bad on the old GPX250 when I weighed 130kg, so ignore me and just listen to Dave#3

[fadz90]

errr
i weigh about 66kgs so that department is good, and also i dont want to be to cocky and learn how to ride to extreme just yet, as a fellow l plater brethern of myn fell of his bike beacuase of this reason. SOOOOOO i'm going to take my time and learn on it

also i was thinking of buying a zx10r but everyone is telling me that a 600 would do the same job, i guess ill just have fun with this bike then worry bout the 1000/600 theory later.

cheers all!

[Blurr]

based on this I am confused why you want more power

Mate, I tried but I can't understand WTF he's on about, teh fcknig diot cnat splle for toeeff
