    Refer back to the early pictures, the EXUP valve fell out long ago. It was loose and about as unsiezed as it could get. I can't figure why both the cables were snapped off in that case!

    Looking at the parts book O have ordered new bush / collar bits as well as cables. Looked like it had been non functional for quite some time!

    It all Turned to Shit Today!

    After I came back from Grub and Nasty's the idea was to slip out to the shed and twiddle with the FZR! The only way to get these projects finished is to try and keep em moving by doing a something every week no matter how small!

    The best laid plans of mice and Paul in NZ were short cicuited buy a shrill and girlish 'whats up with the toilet?' coming from the toilet.... Well OK someone IN the toilet - not the actual toilet...

    Anyway - living below the street level we have a sewage pump and a sump that the pump lives in - if the pump stops pumping - about a week late the toilet stops fushing and I go fishing for the pump - it lives on the end of a chain, a pipe and a cable.... The cct breaker had tripped meaning the pump had jammed so up she came - I'm happy it was a cold day!! (ie not a HOT one)

    Phooooaaarrr! PEEEEEEEYOUUUUUU!!!

    The offending idem of femail sanitary equiment was removed, this were flushed, washed and hosed and since I was litterally now covered in shit I cleaned the sump up at the street as well... had to be done! (bleugh)

    Back to the shed - 2 hours gone.....

    Grabbed the end cover and scraped all the knead-it off the cracks. Tapped a few bits straight and removed the paint ready to see if can be repaired! Yurk! Looks GRIM! Check the spare cover - feck - that looks worse!! Oh well - we will see what can be done!

    OK - having halted progress we popped the carbs up on the bench for a look see. The bikes been running rich so I was keen to see if the flots were OK and the float needle was working. I'll check the float height later but this was really an assess the condition and clean up session.

    I started at the top. I wanted to see if the diaphragms that lift the slides and needles were OK. Yup! Amazingly good condition - needles were erm - OKish and all at the same height so it was a good clean and put back together...

    OK - down to the float chambers....

    Only minimal dirt here! Pulled the jets out and blew them through, checked the floats - (looking for cracks) - and the float needles that shut off the fuel when the level is right. (little rubber tipped thingy) Chuckkled a bit because they are nearly identical to the amal ones...

    All OK - so put it all back together and cleaned it all up!

    Came up OK too - well good enough!!

    Nice!

    Except for the poo. Well done on avoiding a plumber's bill.

    hey dude my mate has one. i was at Winja's place one day after i binned it, and he said they do and they make a realy good bike because the 400 frame is aulimun and lighter than the 600's stell frame. but i also got told that the fzr400 and bigger fzr's have a problem with wavey disks, leaking fork seals and crap clutchs. hope that helped you in some way.

    So no clues in the carbs then so far? So why would it have been running rich? Jet sizes OK? Choke stuck on?

    Keep up the good work.
    Cheers

    Carbs weren't installed correctly when Paul got it. There is a suspicion that the inlet rubbers weren't sealing/fitted correctly when Hels had it.

    Wouldn't that make it run lean? Or would the dodgy inlet track cause the fuel to fall out of vapourisation or something?

    Cool photos. I like this thread, I get to feel all the excitement of doing my engine rebuild without the money and stress and bruised fingers

    Paul, it's OK, everybody knows your shit doesn't stink anyway.

    You'd think so, wouldn't you? There are many mysteries in life and this FZR is one of them.

    The best part is surely we're going to have a coming out party when it makes its rebuilt debut?

    To tell you the truth - I don't know what it was running like BUT the evidence indicates it was rich. Thats why, as you mentioned I was keen to look inside the float chambers. Having said that - the exhaust valves on 3 cylinders were not sealing properly so perhaps the 'richness' was plain unburnt fuel being dumped into the exhaust. Certainly, with lower compression the combustion process may not have been working quite as the engineers at Yamaha designed it.

    What I'm hoping to do is pretty well base line all the settings and start with an open mind. Ideally I'd like to replace as many inlet rubber bits as I can as leaks there really screw things up.

    Getting the EXUP valve to either work or remove it will be a big help I think and I have not looked at the air filter yet (I will be replaced regardless).

    Its all fun thus far and I hope entertaining.

    Cheers

    Thanks for the information - looks like there is a bunch of options including a 600 crank into a 400 engine etc etc. Its also expensive because you need to swap the electrics and cooling system as well (make sense). Best option for me is to make what I've got good again - fork seals etc are no worries and discs are discs - they all warp eventually...

    Only some 600 engines are suitable - I had a list someplace but - well I'm not going that way (yet) so i lost it...
