dont you think it may be better running it up to temp b4 u set mixture?...i would have thought that just might make a diff?

Re: stuttering fzs 600 - Dead Eye - 12-09-12

Everybody is probably thinking it, but carbs (and engines in general) are still not fully sussed in my mind. So; the mixture screws increase / decrease the amount of fuel that is being drawn by the carbs (or something to that effect) so wouldn't increasing the jet sizes have the same result as turning the mixture screws out? Of course you are still running a standard can and it shouldn't be necessary but...

My other random thought is, what if fuel pressure is low? Could a half faulty pump or filter be restricting the fuel flow and preventing enough from getting through? It's a bit of a twist on the same theme that has been followed with fuel starvation...

So much has been discussed but its like 20 pages back and I don't want to go re-read this entire thread - it would take all night Tongue

Re: stuttering fzs 600 - darrsi - 13-09-12

Still not happy with my bike between 2000-3000rpm, so it's booked in to PDQ Monday week.

It WILL get sorted, albeit the issue of a small fortune, but the man who deals with it is a genius, so i'll report back when it's done and let you know what he found!

It seems to run fine sometimes and other times it feels like its running out of fuel and hesitates about 5000 rpm usually when gassing it to overtake :eek . I find if i hold the throttle open it hesitates then clears. It has a micron race can and standard air filter. Any help appreciated

Mine was the same, would hold back for a second or two and then start pulling. New air and fuel filters fixed it. About £13 and £5 respectively from Wemoto.

Re: stuttering fzs 600 - nickodemon - 13-09-12

Just ordered a fuel filter to see if it helps. Thing is sometimes it runs fine, so i would be more inclined to think its electrical, but for a fiver it's worth a punt.

Re: stuttering fzs 600 - nickodemon - 15-09-12

Replaced fuel filter. Noticed when the fuel ran out the old filter it was orange in colour. I think my problem is rust in fuel tank. When i looked in fuel tank it looks spotless, so it must have rust at the bottom :\

if you take the tank of and remove the tap and fuel guage sender you can flush it out quite easily Big Grin
