stuttering fzs 600

[red98]

I will try the filter back in at the weekend and let you know how I get on.

I just had a thought though. A friend checked the bike out for me a few weeks ago and commented that 1 cylinder was running hotter than the others (down pipe was noticeably hotter from startup). The other three cylinders were running a little rich(petrol smell) I will check the plugs at the weekend to to confirm this. Anyway a lean mixture would get even leaner with a new filter, so I wonder if one cylinder is too lean at high rpm and is causing the stuttering?


assume a carb balance may be the simple answer as in the long term, I cant simply stick the old, clogged filter back in, to force the bike to run rich.


Does this sound plausible though??

ummmmmm .....not sure about that  ......start by swaping the filter...i dont think thats the problem but once swaped you can forget about it  .....balancing the carbs is always a good thing    do you know when it was last done ?
