AndiG Posted June 3, 2009 Share Posted June 3, 2009 Firstly, hello everyone! This is my first post and already looking for somehelp.....sorry!! I am taking delivery of a 1989 FZR 1000 EXUP tomorrow (always wanted one!) and apart from the exup valve being seized it's really clean! So, to my first question.......where isbest place to find an EXUP valve (servo still fine)?? Also, would a FZR 400 valve work (as there seem to be a few of those about!!). Lastly,.....I've read the spec of the bike and it states the tyre sizes as front - 130/60/17 and rear 170/60/17. Can more commonly available tyre sizes fit....to get more choice?? Thanks very much all......... Link to comment Share on other sites More sharing options...

Hi Andy to the forum there is very little chance of a 400 valve working physical size plays a part in this !!! with care & time you may be able to fix the original valve post back with what the valve is 'doing' Regards Jim Link to comment Share on other sites More sharing options...

Unfortunately, the original valve has been disposed of by the previous owner (my mate Mark!!) and so can't go down the repair route!! Link to comment Share on other sites More sharing options...

Regards Jim Ermmmm........I'm not sure as i've ridden the bike and it goes great?? The servo is still there and working but he has a stainless link pipe and can on the bike. It's a bit "fluffy" below 4k rpm but then pulls great! I'm no mechanic buddy so any info you can give will be greatly appreciated. Thanks again Jim Andi Link to comment Share on other sites More sharing options...

rf9rider Posted June 4, 2009 Share Posted June 4, 2009 The FZR1000 Exup valve is the same as the YZF750. (its the only bike that shares the same exup valve with the FZR1000) The valve cover, pulley wheel and cable bracket are the same on the Thunderace, Early R1`s, YZF750 and FZR1000. It will run sluggish below 4000 rpm without the valve, and its a long/costly job to try and re-jet around the problem. Link to comment Share on other sites More sharing options...

YZF750's & Thunderace's where not born in my day but as the engines are different I would guess that the processor that controls the valve would be different so you may find the hardware to fit (exhaust pipes, valve, cover & cables etc) but finding the correct (or a one that will work) controler may be a bit difficult !

Regards Jim Thanks again guys!! OK...... I've spoken to my mate Mark and basically it will need everthing bar the servo!!! but he reckons getting an aftermarket set of headers will remove the need for the exup valve and cure the low down "fluffyness"!! Is this the case?? If so.....i have a set of xjr headers available and wondered whether these could work????? Thanks again guys...........................

Regards Jim He says he still has the Exup servo fitted, so no problem mate. The CDI/ECU only controls the servo motor, its really not a problem.

You can get a set of stainless aftermarket pipes with no Exup valve, but the FZR will still need a small ammount of tuning. I bought a set for my Thunderace, bolted straight on, no tuning required, but the Ace and FZR have different ammounts of cam overlap. Have a look on Ebay, Sandybikespares is where i got mine from, good people, find there listings and speak to them on the phone first if your not sure.

I'm actually watching a set of headers from them and think i'll go for it!! £200 plus delivery. Can i also ask buddy.......when you say need setting up do you mean a dyno kit, dyno time etc..... i've only had one cardb'd bike and never fettled with it!! Got a PC111 and custom map on my Mille, fuel injected though so unsure where to start getting it sorted if it doesn't run sweet?????

Thanks again mate........................Andi They claim that the headers are a direct replacement with no setting up required, although i`d expect to do a bit of tuning to the carbs. It may just need the carbs setting up or at the worst a different set of jets, although much easier to do this than try to set up your original headers with the valve removed. And on the plus side with the new ones, no more Exup valve to service! Link to comment Share on other sites More sharing options...
