When it comes to nuts and bolts buying specific Yamaha parts can be expensive...have more fun and save money getting stainless steel bolts of every type on ebay...so far I have replaced most of the visible hex bolts on crankcase covers , handlebars etc with nice SS bolts...cost next to nothing and free postage...if u don't mind waiting a couple of weeks..

Cool..
can u pay by Pay Pal...?     my email

if u let me have ur address I'll post to u

I accidentally bought two throttle cable sets for me Fazer 600...u can have a set for £15 inc. postage...
They are from Germany...marked HIGH TECH STEEL ROPE CABLE......MADE IN EU.

JAYSUS...!
if ur going to all that trouble just get a secondhand set of stainless steel downpipes which will look (and be) a whole lot better....

ARF...finally sorted my carb issues...
First I had a bogging down while tipping along at low revs...open the throttle, and nothing ... for a few secs...then start to accelerate away.... turns out to be a clogged pilot jet...makes sense, since pilot jet is helping at low revs, not just idling, and wasn't working properly, but once main jet kicks in off we go.
Second problem...revs won't fall back to idle when throttle is shut off...NOT pilot jet, although some experts suggest that running too rich causes this problem. I went down that road and tried adjusting pilot screws...no difference except lumpy idling.
Put pilot screws back to factory setting.
NOT throttle cable, i fitted a new one and made sure it was snapping back all the way. NOT a partly open choke circuit.
Other expert points out that shutting the throttle should drop all needles into main jets and close them SMARTLY. If one needle is not falling for some reason (diaphragm damaged/not seated correctly or some tiny obstruction) then there will be a delay in revs falling.
I took off the carbs, and without dismantling them completely opened the tops and made sure the diaphragms were seated correctly and the sliders were working smoothly....BINGO..! Blip the throttle and she revs up and falls back like a good FZS should...took it for a burn and experienced bliss of perfect throttle response....this video was a big help -
thanks for the comments and advice

Thanks for informations and thoughts. I now understand wot pilot screws do. That video with the Italian guy is good... My bike is STILL having throttle shut off delay...when I shut the throttle the revs don't go back to idle SMARTLY.
Changing the pilot adjustment screws didn't make any difference...so back to factory settings. Used WD40 and butane to check for air leaks...negative. Checked my sliders and diaphragms...all looks OK...still no difference. New throttle cables...STILL revs won't drop back after throttle shut off...
Anyone had similar issues......??

They look similar to a set I fitted to my 5DMC...I had a bit of trouble lining up the bracket with the mounting bolt... a bit of force involved but I got them on OK...cargo straps are great for pulling things into line

Thanks for the tips lads....I tested for air leak but all seems OK.
When I think about this it's unlikely that the pilot jets are causing this problem (revs not dropping smartly down when I shut off the throttle).....since pilot jets only supply tickover fuel...
I suppose I will fit new throttle cables...but I'm not all that opti mistic that will solve the prob....?

ARF...!  thanks for the help...I did look up some carbs videos and discovered that the pilot screw is for allowing fuel, not air into the idle circuit...

Bought a couple of cheap Chinese "Projector" spotlights on Ebay...stuck them on the FZS600. OK they are cheap and they look cheap, but WOT a difference...!
Now I can actually ride at night.

PS...you do need to take off the radiator and fan.... G'Dluk
