Re: Leaking Fazer FZS600 - aquilaalba - 21-12-15
I've attached photo showing pipe leaking coolant, will get some server details later on and will take few more shots tomorrow - and will upload some photos. As for the coolant - on second attempt it started to leak coolant after warmed up, but this can be due to the level being too high still in the expansion tank, will take it to the workshop tomorrow to drain the excess and see if it still leaks.

Trace the small pipe from the filler cap under the fuel tank back to the expansion tank.
That pipe should attach to the bottom of the expansion tank.
The pipe in the picture should go to the top of the expansion tank near its filler cap
It would appear from the picture and what you describe to be connected in reverse.

hope you get it sorted soon mate... intresting handle you got yourself! are you in Devon or Cornwall?
Re: Leaking Fazer FZS600 - aquilaalba - 22-12-15
Now then, there has been some development in issues with my Fazer, now I now for a fact that it is incapable of running daily for now, until the amendments are made...
- unfazed - you were spot on the problem I guess (photo 1), leaky pipe was actually a pipe that other end was connected to the bottom of the expansion tank on the front, it was going up to the top of the frame, bent there and going back down... I suppose it should be connected to the breather nipple on the tank (if I'm reading this correctly) - here's the next question then:
- two nipples on the bottom of the tanks (photo 2) - I presume one should be connected to a pipe running under the bike to release water from little breather / channel on the rim of the tank that catches the rainwater. Other one probably is the breather for the pipe in question - one from the bottom of the expansion tank... Am I right, if so, which one's which?
- the mysterious loose bracket - this is it, pictured (photo 3) - it's the pipe running from the top of the rad to the expansion tank, or at least I think this is what it is.
- latch should be stuck open or closed when not operated? Maybe the lock is shot and someone pulled it tight to keep it open, as it doesn't close at all.
And last issue - I was going to take the Fazer out for a spin, but good lady noticed my rear lights are gone... Bulbs are all fine, wires connected and the odd part - it all lights up when I press the foot brake, no reaction to lights switch or front brake lever. Just to add, just replaced the H1 bulb on the front and it seems someone hacked it as it stays on all the time. There is a slight chance that this triggered the rear cluster problem, as since I had the Fazer this bulb was out, I did not test the rear light, but I think I did test both brake lights and they were functioning... No lights on the tail at present, unless I hit the rear brake...
Re: Leaking Fazer FZS600 - unfazed - 22-12-15
Reroute you Fuel pipe under the square frame cross piece.
Under the fuel pipe in its present location is a 6mm bolt hole for attaching your loose bracket along side a locater hole for the fork part and the pipe attached to the bracket is routed between the back of the two right hand carbs and down the right side of the engine behind the clutch cover. the other end of the bracket attaches to the sirbox with another 6mm bolt
You are missing a little funnel piece see picture, it clips to the to the bracket. The drain holes from the tank drip into this and out the pipe attached to the bracket.
Picture below show most
Re: Leaking Fazer FZS600 - darrsi - 22-12-15
The single filament H1 bulb on the left side is your headlight, that's meant to be on all the time.
For some shit reason the twin filament H4 bulb on the right side is wired for use with either your flasher/pass light button OR high beam only.
The mod that most people do is to make the lower filament stay on all the time as an extra low beam with the H4 bulb.
If the mod hasn't been done then the lower filament of the H4 bulb simply wouldn't ever be used or light up at all.
Re: Leaking Fazer FZS600 - aquilaalba - 24-12-15
Where should the small pipe coming off the bottom of the expansion tank be connected then? It is just hanging at the moment, but surely should be attached somewhere.... This Fazer of mine seems to be bodged in few ways, it has been a write off as I've found out today upon receiving of the logbook... I'm starting to think about giving this one back and getting another one, yet it had a new nose cone, few things done to it, might just get it back straight and carry on - rides fine, managed to tighten up the triple tree main nut so no loose movement in there any more. As for slight misfire at low revs - will change the caps, this should help. Altered the TPS as it was out a bit, this improved it a tat. Now the cooling system and dodgy electrics...
Re: Leaking Fazer FZS600 - darrsi - 24-12-15
Is the bike the right way up, sounds like it's upside down? :lol
Dunno if it's any help but look at section BODYWORK > SIDECOVER
Looking at the photo it may just be a breather pipe, but i'm not 100% on that?
https://www.yamahamotorcyclespares.co.uk/spares/modelImage.asp?modelID=9657&uID=0
The manual may shed a bit of light here as well, but i doubt it for the expansion tank.

Re: Leaking Fazer FZS600 - darrsi - 24-12-15
Yeah that would make total sense, I wasn't quite sure what he meant to be honest.
Re: Leaking Fazer FZS600 - aquilaalba - 26-12-15
What about the other pipe then coming off the top of the expansion tank? It was connected stupid way round - bottom hose was leaking as it would and will be reconnected to the top of the thermostat housing now - this should solve the leak...
How about the top hose - I take it it's only the breather pipe for the expansion tank - is there any connector it attaches to or needs to be placed? I did check both Haynes and other service manuals and there is no routing for these shown... Fingers crossed that should cure it, will check the rear light cluster from scratch with the diagrams printed and that should be ok as well. What scares me is that it shows that some butcher was mending the bike, not sure what else to expect... As said, rides nice, if anything, it bangs into 1st gear a tat too harsh, even though I've cut down on the low revs.
Re: Leaking Fazer FZS600 - darrsi - 26-12-15
If you ever have a blocked up coolant system the expansion tank will fill up and boil like a kettle then dump excess liquid out of that pipe on to the floor.
If you adjust the clutch properly from the bottom end first then tweak it at the lever end that may help when selecting first gear.
Also if you roll the bike forward a few inches then select first it won't be so clunky as well.
Re: Leaking Fazer FZS600 - unfazed - 26-12-15
Pages 12 to 15 of the supplementary service manual give most routing of hoses/pipes/cables.
4 pipes/hoses go down the rear of the clutch cover
Coolant Over flow
Tank Over flow
Carburettor pipes.
Re: Leaking Fazer FZS600 - aquilaalba - 26-12-15
Which manual is it? Did check both that I've got - Haynes and FZS600'98 Service Manual - couldn't find the routing of the pipes... Will get them re-routed and post back. Might just strip the lot and start from scratch rather than finding more and more problems with every step...
Re: Leaking Fazer FZS600 - unfazed - 27-12-15
Download the fzs600 2000 supplementary manual.
There should be a hose guide behind the clutch and close to the stand bracket.
I will get and get a photo tomorrow if I can
Re: Leaking Fazer FZS600 - aquilaalba - 27-12-15
Just found it and yes, it does show it more clearly. Will have to check all the routing, get the clutch adjusted and check compression just in case, as it has that slight misfire on low revs, considering someone put it back wrong, I'm starting to think did it overheat and caused a problem on pot No.1 or is it just cap problem? If it'd be something more substantial though it would be manifested at higher revs and under load and it doesn't so shouldn't be the case, but doesn't hurt to check. Also electrics need looking at, so plenty of things to do before I'll be able to properly run it. Did my Mod 1 on my old Divvy though, now Mod 2 will be most likely on the Divvy as well, I was hoping to use Fazer for both but I need to make sure it's reliable and without any issues first. Thanks for all your help, I'll post an update as soon as I'm at it. Thanks for info on another manual, helps a lot as well.
Re: Leaking Fazer FZS600 - aquilaalba - 31-12-15
Right. As for the lock on the side of the bike (seat) - just needs adjusting I suppose and by not being able to fill the tank last time I tried I've found out that the spare key is not a spare key, but the main one is only for the ignition and other one (genuine) works with seat lock (which is not engaging anyway at present) and tank lock. Next thing - the pipe in question is routed now from bottom of expansion tank to the nipple on the radiator, as should be. Leaking should be gone now. Here's another problem, did look into manuals but can't find such pipe connected - pictured - it was connected from the radiator top (by the cap) nipple to a pipe on top of the carbs??? On the manual it seems that copper pipe sticking out of the carbs unit is not connected to anything, next thing it might be that I was getting coolant in carbs causing misfire.... Jeez... Pipe shown on photos below is the one I disconnected, first photo shows the location of the pipe roughly and next one shows zoomed in view of where the pipe is connected to - other end is not connected at present and I think the whole pipe should just come off altogether.
Happy New Year everyone!
Re: Leaking Fazer FZS600 - unfazed - 31-12-15
That pipe should go to the radiator on the right hand side below the main radiator hose.
Its compatriot from the other side of the carburetors should attach to the Thermostat housing underneath the temperature switch and behind the radiator fan switch.
Re: Leaking Fazer FZS600 - aquilaalba - 07-01-16
Right... All (I guess) is connected right, the pipe going from the top of the expansion tank was going through the unknown (earlier) bracket and past that it was connected to the right side of the radiator. It is now connected as follows: bottom of the expansion tank to the nipple right under the radiator cap on thermostat housing, top pipe of the expansion tank is connected to the mystery bracket found earlier and nowhere else (effectively acting as a breather (which it should be, isn't it), pipe going from the right side of the carbs (small pipe pointing up from the carbs) is connected to a nipple on the right side of the rad and lastly similar upward small pipe from the carbs is connected to the thermostat housing nipple located around temperature switch and fan switch as per unfazed's post. Thanks to all of you who helped me here, glad to have this finally sorted, will test it this week providing the rain gets milder. Next on the agenda is mocked up electrics, but we're getting there. Will readjust the steering triple tree bearing as I bought the appropriate Yamaha (-ish) tool for the torque wrench. Better to get it right before starting to ride on it and mocking it up - it was completely loose, you could feel clunking when applying brake, going over potholes, etc. There are some issues, but all will be addressed. Eventually, anyway...
)) Thanks!
Re: Leaking Fazer FZS600 - aquilaalba - 09-01-16
Just to let you guys know - did all the alterations to the pipework and I can proudly announce that it doesn't leak, rad gets the temperature after some time, so it seems that my cooling issues are sorted. Electrical part next, plus the triple tree bearing tension readjustment. Easy. Thanks again for all your help, I'm afraid you'll hear from me again!
