stuttering fzs 600

[red98]

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

good point on the fuel pump and filter  ....i bench tested the pump and all seamed fine   could change when its under pressure though  :\ .....filter was clear and again seamed fine.but as they are cheap will probs replace
