hey everyone. i was just wondering if there is any thing that can be done to the fzr250 to give them, a bit more power? thanks
Where abouts are you lacking? You should get your bike tuned by a mechanic who is familiar with FZR's. Straight line speed isn't really important, if you aren't scraping your pegs or ripping up the bottom of your fairings around corners then you don't need a faster bike. Take it on the track and you will experience a thrill far greater than just going 200kmph in a straight line, or accelerating with greater torque.

a 400 engine would be awesome!!!, does anyone know what that would cost? and whats involved? and red paint would be way too powerfull for me...lol
because by buying an fzr400, he still wouldnt be making his fzr250 any faster which was the question he asked in the 1st place!! sorry i had to be a smart arse. id agree that as its only a 250 you shouldnt bother tuning it but if you must id see about fitting bigger injectors in the carbs, a new exhaust system might give you higher output in the high end, but without the exup you'll loose drivability through the low and mid range. you might even find competition spark plug for it, and a better air filter.
What? I agree with the idea of not re-jetting or anything but having the fzr tuned by someone that knows what they are doing can make all the difference. If you get that sorted and still want more power, get a bigger bike. You will just be throwing your money away. Over here you could buy a FZR 400 for the same price as the 250. I know I would love to have one without all the screwing around involved with refitting a new engine in the 250. http://bikepoint.ninemsn.com.au/DesktopDefault.aspx?UsedBikeID=939941&TabID=3424&Alias=bikepointau <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->
Yeah I have to agree theres no much you can do to them to make any real noticable gain. Its not like your racing the thing...so by changing certain parts wont give you that great of gain. Standard things that come to my mind would be: Fitting an aftermarket filter for better flow, Maybe a lighter exhaust if you can get one..but then u miss out on exup..which I dont think does jack s**t on the 250 anyway <!-- s:rofl: --><img src="{SMILIES_PATH}/icon_razz.gif" alt=":rofl:" title="Rofl" /><!-- s:rofl: --> Iridium spark plugs. Thats all I can think atm..and the gains you will get would be very minimum...so theres no much of a point. Maybe try reducing the weight of the bike? If you can drop this by like 10kg...this will not only increase acceleration..but also improve handling. Your best off just getting someone who knows what they are doin..to give the bike a good tune and get it running nicely
One thing i've been thinking of doing since i've got at least another 6 months on the 250, is messing with the sprocket ratios to get more punch off the mark. Going to less teeth on the front sprocket and/or more teeth on the rear would definately give it more acceleration off the mark (at the expense of some top speed which doesn;t really bother me) might even make it possible to wheelie the thing. Anyone done this? At the least, it could liven things up a bit until upgrade time <!-- s --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="" title="Very Happy" /><!-- s --> .
It is a less expensive way to increase acceleration. I would recommend changing the chain at the same time. Now this is just my own personal opinion, but I'd only go up on the rear. The current gear ratio on my bike is 16 teeth on the front, 47 teeth on the rear. This equates to a 2.93 gearing. This is a stock rear and 1 less tooth on the front. Because of smaller front sprocket, the chain has to turn around a smaller circumfrence. It also shortens the height of the chain travel above the swingarm. I'm chainging to a 17/50 which equates to a 2.94, so I'm not really changing the ratio. 17 is stock on the front. The reason I'm doing this, other than the fact that I'm going on a 3,000 mile trip, is I'm getting some odd bumps and "feelings" from the chain as it rides on the chain guide/swingarm protector.
thanks tim. my chain is already pretty much cactus anyway so its an easy decision to replace sprockets/chain all at once. Now the real trick will be to find a non-standard rear sprocket for a 17yr old grey import jap bike - the search begins...
yer i rekon.. i hate tryin to find parts for these bikes... but maby bike biz in parramatta will have em' ill find out this weekend... does anyone know what i'd expect to pay for this?
Bike BIz in Parra just quoted me Chain $120 Front Sprocket $15 Rear Sprocket $42 I presume that was stock ratios. Amanda
17 years old? So you have a non-EXUP FZR? Why not sell it and buy an FZR with EXUP? You would be suprised how much of a difference it makes.
