Angry zxr 400

[westie]

Ok I just bought my second zxr 400. The last one never made it to the track
This one has indicated it might be keen to get there. The first indication was the muffler. After market and New looking(on an old bike).
The second and most give away the air box looks like swiss cheese with thousands more holes drilled in it!!!!!!
Once started for the first time(bought site unseen) it reved out quicker than you could say yes to a root.....(not australian there's a 't' in there)
I was planning on making it a stunt/street fighter. But what about the track? Any one got any parts for these?

Advice?

I need anything from the steering head forward. ANYTHING?
Especially the throttle cables

Yeah bro,
Race it. The ZXR is a good wee bike for F3. You have a good strong local club scene up there. Get out to Pukekohe and have a chat to some of the organisers and other F3 competitors.

well you have done the exhaust and carbs.. does it have a ram air intake? if not make one up. get a 17" rim with good rubber higher set pegs, get suspention sep up correctly, run it total loss and get some race fearings for it.. the first thing i would do after a ram air intake is to dyno tune it and get it jejetted as its probably running real lean

[westie]

you wont beat me tho so invest in some track time 1.10 is a respectable lap time for that bike at puke

Ha ha. Just did my first track day at taupo on my fireblade. Was great fun but definately need some telling how to do things.
Should nt take much to get the zxr on the road. When is the next puke day for this class?

[FROSTY:Me]

Get thine arse onto the track and do a track day or two.
My experience with ZXR400's says get the brakes sorted and service the suspension.If its a roadie that hasn't been modified you need to remove the speed/rev limiter for pukie or she will stop at 190km/h
You'll be happy for quite a long time with the ground clearance and how she runs

Will do frosty boy.
Cant wait to get me leg over!!!!
I have to replace all the seals in the forks and brakes As they all were damaged in a fiery incident.
Any tips on the brakes, as the forks should be straight forward.

i agree.....
track days rock for practice and getting used to lines.....
and asking lots of questions....

Didnt do many of those things at taupo on the weekend. It would have been funny watching a blade go round the track in really high revs but not going fast. lol So I like the sound of a high pitched squeal. Who doesn't.

So Coffee.... Friday?

With the brakes Yup Order a seal kit then strip both calipers and the master cylinder down. By that I mean all pistons out completely from the calipers. Polish the sides of them till they gleam. Clean out the master cylinder.Fit New seals and use rubberlube when you refit the pistons.
I'd fit braided lines as well.
Seems like a lot of work I know but you won't believe how much better the brakes work
With the back brakes as long as they work ok Id just clean up the pistons and put in new brake fluid.The idea being simply to reduce the drag fromthe back brakes as much as possible but still have effective brakes

personally I don't think running total loss is a must...more trouble than its worth in my opinion (my opinion probably isnt worth much but anyway)

I'd say get on and ride it and worry about the mods when you are being held back by the bike

Thats probably what I'll do. Both ways are good advice..
When the time comes I'll rip it to bits(if it hasn't broken already) and from the ground up make it mean!
Dreams are free huh.

[westie]

Thanks for the advice frosty. Will start to devour the front end tonight then. Should be able to spend all next weeks pocket money before thursday on it.

[Tim 39]

yea like what was being discussed in the pro twins thread, a fast rider on a standard bike is usualy quicker than a slow rider on a fast bike.

spend money on the track time, and just time on the bike (cleaning/bike prep etc)would be my advice

Jeeze boy you talk some shit.
ZXR400s have 17 inchers as stock.They have very good ground clearance as stock -TS had his zorst liftin the rear on his before the pegs were decked.Total loss is a waste of time and effort for the small HP gain.Verses the starting issues ayou will encounter.HOW THE FUCK are you gonna dyno tune a bike with ram air you idiot.
Westy my advice based on a couple of seasons racing zxr400's
Do the shocks n brakes. Give the engine a birthday-Oil Filter, do the shims,do sort out the rev limiter
Fit a set of crash bungs and if the fairings mint yea get a glass fairing
I'd also read the -"Wanna go racing ?" thread and get a spare set of levers -they are the first bit to break in an off.
Go do a couple of trackdays then maybee do the last round of the Vic club series in Clubmans 2 so you aint under any pressure.
I totally agree with young Tim.Ride till the bike is the slowing factor then decide what you're gonna do

Your bike sounds like crap. In fact I think that you should get rid of it asap. I would be happy to take it off your hands and see how she races...honestly I would! Trackdays are a good start mate!
