My zxr250

[Buddy L]

I just thought
that ill post a video of my bike
make the rest of you cream your pants.:nya:
Its a 1989 zxr250, 50,000kms, all original fairings:gob: and is quite tidy for its age.
Had to take off that muffler to hear what it realy sounds like!
it makes 34hp at the rear wheel, so its still got a little poke left in it.
Had it for the last 2 years, have got my full licence now but not enough money to up grade a 600cc just yet.

[N4CR]

Hahahaahahah you freeeeaaakk o' nature! Funny vid.

Nice one man, I love that sound of a canless inline 4 250... zxr of course. Sounds so fuckin mean, I got a rather gutted can with similar sounds - no packing and entire baffling tube/system taken out it's just an aluminium holder now...

You get alot of looks riding around with the really loud cans on these, everyone thinks it's a race bike or something. don't let the popo see you though ;)

My current can is alot quieter but still screams enough to hear it fine. Nice vid.. cheers.

[paturoa]

is that a proper bike (KDX) at the end?

[Buddy L]

yer that was my old dirt bike "kdx220" picture of bike is my profile.
i now ride a cr125r.
i had to cut the video down from 25mb to only 4mb so i could fit it on the posting, the rest of the movie had me at the drags, and also dirt bikeing at the beach. with music in the back round all that stuff!

[Buddy L]

ill try and post the one at the drags, managed to to a 14 second pass. beat a gsxr1300 to the 60 foot mark. sticking to the big bikes

[vtec]

Was that a 14.0 second pass or somewhere else in the 14's? Always interested to hear real life experience of quarter mile times, so I can keep collating in my head what different bikes are capable of under real world circumstances.

[Switch]

hahahah nice video. And a VERY nice bike :scooter: :first:

[Buddy L]

it was a 14.745s @142.5kph
that was my first time at the drags, haven't been again.
that pass had a reaction time of a snail with 0.876s:blink:
60 foot time was 2.254s
1/8 of a mile was 9.321s
all of that was done with alot of cluch slipping
could get a faster time if wasn't picking my nose at the start line.
if the maths is done right the bike can manage a high 13second pass,

[Brett]

LOL...love the sound of the canless bike...very very nice. Most amusing at the end too.

Question: Does having no rear can...ie no back pressure pose any threat to the motor? Could it cause it to run lean or anything like that?

[Buddy L]

I don't know about the back pressure, it depends what the motor is used for i reckon, maybe for drag racing i dosn't matter as much because you are only fully tit all the way, for track use most bike are tuned with the exuast in mind, and it helps to suck out the burnt gases better than if their was none, probley helps with engine breaking as well.
maybe but don't quote me on that.

[N4CR]

Been covered quite a bit, you shoulllllddd get enough backpressure from headers and resistance alone BUT you will loose your low end almost completely, my empty can makes the bike have all it's power up top, seems a little more but small usable rev range, it is tuned for a slightly more backpressured version of that can. Hardly goes at all with stock on, can't run properly or quick etc.. strangled. Ricky had a moan about being hard to tune with no back pressure so I replied 'WHAT SORT OF POOFTER RIDES DOWN THERE ANYWAY'. He got the message. :lol:

Some back pressure is good, none.. hrrmm in rare cases might get feathered valves. I can't be fucked searching kiwibiker but search 'back pressure' and see what come sup. Or backpressure... meh. Have fun.

Aeroplanes often have headers going straight into the atmosphere, spitfires, cessnas infact most planes have no silencer at all... just a straight pipe. But they don't have .5cm wide valves...

[Buddy L]

I also bunged a video under the off road forums, under Beach Blast if you wanted to have a look. im going to be making more of these little movies, so any feedback back would be good, what to to better next time and so on,
i no that music in the back ground would be god but it fills up to much space, and can only post the 4mb aloud.

your e.t. does not include your reaction time

[texmo]

Ands thats the factory quotes these bikes are almost 20 years old and will be down on power.

[Mr. Peanut]

Yup... :second: stroooooookes :lol:

[gamgee]

haha it sounded like a rotor when it was idling, bwam bwam bwam bwam bwam bwam...

[Buddy L]

Ands thats the factory quotes these bikes are almost 20 years old and will be down on power.

Nar thats the times that i got,
they print out a little slip after each drag down the stip, and hand back to you. including, r/t, 60 foot, 1/8 of a mile, 1/4 of a mile and top speed.
That is also including your r/t, time starts when the light turns green buddy,
ill put up a post when the next "night drag wars" are on, so others can come down and test it out.

[Buddy L]

my bike makes 34hp at the rear wheel as quoted by redbaron's dyno

[R6_kid]

tex and tristan should be able to quote their 250 hp numbers... pretty sure they both had them dyno'd, and both at red baron too.

[N4CR]

35.5?ps i think it was just under 36. Beats all the other 250's 4's in a straight I have ever raced (alot) so ricky did a good job tuning it. and around corners

Apparently the rr's have more PS on average than the zxr's for some reason they still get beaten on the straights, zxr's haev more torque hahahaahH AHaahsahhHA HONDA IS GAY

[Mr. Peanut]

What was that? :nono:

[N4CR]

What was that? :nono:
HONDA IS GAY HAHAHAahahahaAHAHAHAHAAH YOU ARE GAY CUS YOU RIDE ONE LOILZZZLZL

ZXR FOR LIFE PWNDS HONDURRS
