Re: stuttering fzs 600 - red98 - 18-08-12
gave myself a kick up the back side and got out to the garage......my adapted tool did`nt work as i only have one pair of hands :rolleyes ......so looked at the other one....with slight adjustments with an angle grinder and closing the jaws up in the vice i was able to get one of the valves out
......also tried to get it back in again aswell.....very fiddly with the collets and my fat fingers and the lighting is not too good in the garage but i did manage it 
so will see if i can regrind all the valves on one cylinder tomorrow......fingers crossed
Re: Stuttering fzs 600 - red98 - 19-08-12
Afternoon fazer fettling fanatics......nice day so set up bench in garden and removed all 16 valves
...No horror stories, but I can see why compression was low, all valves are going to need regrinding, cyl 2+3 worse than 1+4 which backs up my compression test figures.Another 90 mins to add to the time taken, not sure what I am up to now. :\
Re: stuttering fzs 600 - red98 - 19-08-12
bit more progress.ive re-ground all the valves on no1 cylinder and re-fitted them
cleaned up well with no pitting ............just another 12 to go :\ ..........another 2 hours to add to the total

Re: stuttering fzs 600 - red98 - 21-08-12
busy at work again now,so not much more done,managed to get out in the garage tonight for an hour and re-ground another 4 valves and re-fitted them
....... getting boring now :\ ........ah well only another 8 to go going to try and do another 4 tomorrow and also measure the shims so i can order them at the same time as ordering the gasket,sounds like a good plan 8) [size=78%] [/size]
Re: stuttering fzs 600 - CRH - 21-08-12

Re: stuttering fzs 600 - red98 - 22-08-12

Re: stuttering fzs 600 - red98 - 22-08-12
easy day at work today so straight out in the garage when i got in.......ground in the last 8 valves
.will re-fit them tomorrow also measured the shims,inlet are ok but all 8 exhaust shims need to go up a size,3 of the old shims i can re-position so i only need 5 new ones....ordered these tonight along with the head gasket from WEMOTO .....£56 delivered...could have got it cheaper but ordering everything from one supplier has saved on postage

hi clive....saw the ebay ad....works out cheaper for me to buy new
but thanks for the tip
Re: stuttering fzs 600 - red98 - 22-08-12
forgot to mention.....another 90 mins to add to the total
Re: stuttering fzs 600 - CRH - 22-08-12
like you say?..may not sort the stutter ...but?...good starting point for getting it right!!!!!!....at least all comp should be pretty equal?...think then mabe mixture screws set to what we said?...then give it a blast???????.....ps?12 1/2 to go!! :rollin
Re: stuttering fzs 600 - red98 - 22-08-12
i wont be that disapointed if this dos`nt solve the stutter :eek ,the bikes been good to me in the ten years ive owned it
,so it deserves a bit of tlc ...but i will know that the engine is in tip top shape 8) ...first thing i shall do when its running is another compression test to see what improvement i`ve got ......will probs adjust the mixture while i`ve got the carbs off as much easier ....i did notice that exhaust valves 3+4 were slightly richer so will be interesting to see what the settings are at the moment .....also need to adjust the plug gap as too wide at moment 12 1/2 to go.......i might just do it....was that a guess or do you know something i dont ?
Re: stuttering fzs 600 - CRH - 22-08-12
.......just going off how long we spent on that busa we did?...but we did do a full engine build?...fkn loved it?..specialy when it fired up and run like a sowing machine!!....think you will notice a hell of a diffrnce, when you do run it again?...there was only one cyl down on the busa and that was a exhaust valve?...but seeing it had done over a 100k we did a full overhaul?...its done 9k now and has never missed a beat!! so!!!!!!!!
Re: stuttering fzs 600 - red98 - 22-08-12
yes a great feeling when it fires up....last engine i done was 2.o m10 bmw ,used three engines and a few new bits to make one good un and that started on the button....sweet as a nut....and a great big smile on my face
Re: stuttering fzs 600 - CRH - 22-08-12
i still do think that we have the answer on that list?.....so hopefully this time you will have the answer you want? :rolleyes
